[0002] 2. Description of the Related Art Conventionally, bead holding tables and bead holding trays that hold adjacent beads so that they are in contact with each other are known (see Patent Documents 1 and 2). The bead holding stand has a substrate and a holding portion formed in the vertical and horizontal directions of the substrate and holding adjacent beads in a contacting state. The holding portion consists of a through hole formed through the substrate and locking edges formed in at least three places around the periphery of the through hole.

[0003] [Patent Document 1] JP 2015-181915 A [Patent Document 2] Utility Model Registration No. 3132468 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the bead holding bases and bead holding trays described in Patent Documents 1 and 2, the through holes and recesses are arranged in a hexagonal shape, so even if adjacent beads are connected and fixed to each other, the only three-dimensional object that can be created is one in which multiple beads arranged in a hexagonal shape with an outer angle of 60° are monotonously repeated, and the design of the three-dimensional object is poor.

[0005] In view of these points, the present invention aims to provide a plate, a three-dimensional object, and a method for manufacturing a three-dimensional object, which can achieve "improved design of the three-dimensional object" by having a pentagonal hole arrangement portion, etc. [Means for solving the problem]

[0006] The plate 1 of the present invention is a plate that holds and connects multiple adjacent spheres Q, and its first feature is that the holes 2 that hold the spheres Q have a pentagonal hole arrangement portion 3 that is arranged in a pentagonal shape in a planar view.

[0007] A second feature of the plate 1 according to the present invention is that, in addition to the first feature described above, the plate 1 also has a hexagonal hole arrangement portion 4 in which the holes 2 for holding the spheres Q are arranged in a hexagonal shape in a planar view, there is a portion in which the pentagonal hole arrangement portion 3 and the hexagonal hole arrangement portion 4 are adjacent to each other, and the distance 3L between the centers of two adjacent holes 2 in the pentagonal hole arrangement portion 3 is approximately the same as the distance 4L between the centers of two adjacent holes 2 in the hexagonal hole arrangement portion 4.

[0008] A third feature of the plate 1 of the present invention is that, in addition to the first or second feature, it also has a triangular hole arrangement portion 5 in which the holes 2 for holding the spheres Q are arranged in a triangular shape in a planar view, and the distance 5L between the centers of two adjacent holes 2 in the triangular hole arrangement portion 5 is longer than the distance 3L between the centers of two adjacent holes 2 in the pentagonal hole arrangement portion 3.

[0009] Due to these features, by providing a pentagonal hole arrangement section 3 in which holes 2 for holding the spheres Q are arranged in a pentagonal shape in a planar view on plate 1, which holds and connects multiple adjacent spheres Q, unlike Patent Documents 1 and 2, the holes 2 are arranged in a pentagonal shape. Therefore, when adjacent spheres Q are held and connected to each other, the exterior angle is 72°, and the multiple spheres Q arranged in a pentagonal shape form a three-dimensional object 10 with a rich variety, thereby improving the design of the three-dimensional object 10 ("Improved design of three-dimensional object"). Incidentally, the plate 1 according to the present invention can also be called a "sphere connecting plate" since it holds and connects a plurality of adjacent spheres Q to each other.

[0010] Furthermore, by providing a portion where the pentagonal hole arrangement portion 3 and the hexagonal hole arrangement portion 4, whose center-to-center distances 3L and 4L are approximately the same, are adjacent to each other, a three-dimensional object 10 can be created having a portion where a plurality of spheres Q arranged in a pentagonal shape with an exterior angle of 72° and a portion where a plurality of spheres Q arranged in a hexagonal shape with an exterior angle of 60° are adjacent to each other, thereby making it possible to further improve the design.

[0011] Furthermore, by providing triangular hole arrangement portions 5 whose center-to-center distance 5L is longer than the center-to-center distance 3L of the pentagonal hole arrangement portions 3, etc., further "improvement of design" can be achieved.

[0012] The three-dimensional object 10 of the present invention is a three-dimensional object formed by connecting a plurality of spheres Q, and its first feature is that it has a pentagonal sphere connection part 13 where the spheres Q are connected in a pentagonal arrangement.

[0013] Due to this feature, by having a pentagonal sphere connection part 13 in which the spheres Q are arranged and connected in a pentagonal shape, unlike the cases in which the bead holding stand or bead holding tray of Patent Documents 1 and 2 is used, the pentagonal sphere connection part 13 connects multiple spheres Q in a pentagonal shape with an exterior angle of 72°, resulting in a three-dimensional object 10 with a rich variety and improving the design of the three-dimensional object 10 ("Improved design of three-dimensional object"). Incidentally, the three-dimensional object 10 according to the present invention can also be called a "sphere-connected three-dimensional object" since it is configured by connecting a plurality of spheres Q.

[0014] The manufacturing method of a three-dimensional object 10 according to the present invention is a manufacturing method of a three-dimensional object formed by connecting a plurality of spheres Q, and the three-dimensional object has a pentagonal sphere connection portion 13 in which the spheres Q are connected in a pentagonal shape, and a pentagonal sphere connecting process P is provided in which the plurality of spheres Q are connected at the pentagonal sphere connection portion 13 using a pentagonal hole arrangement portion 3 in which holes 2 for holding the spheres Q in a plate 1 that holds and connects the plurality of adjacent spheres Q are arranged in a pentagonal shape in a planar view.

[0015] Due to this feature, by providing a pentagonal sphere connecting process P in which multiple spheres Q are connected at the pentagonal sphere connecting section 13 using the pentagonal hole arrangement section 3 of the plate 1, unlike the case in which a three-dimensional object is manufactured using a bead holding stand or bead holding tray as in Patent Documents 1 and 2, at the pentagonal sphere connecting section 13 connected in the pentagonal sphere connecting process P, the multiple spheres Q are connected in a pentagonal shape with an exterior angle of 72°, resulting in a three-dimensional object 10 with a rich variety and improving the design of the three-dimensional object 10 ("Improved design of three-dimensional object"). The manufacturing method of the three-dimensional object 10 according to the present invention can also be called a "manufacturing method of a sphere-connected three-dimensional object" since it is a manufacturing method of a three-dimensional object formed by connecting a plurality of spheres Q. Effect of the Invention

[0016] According to the plate, three-dimensional object, and method for manufacturing a three-dimensional object of the present invention, it is possible to realize "improved design of the three-dimensional object" by providing a pentagonal hole arrangement portion, etc. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. <Overall composition of Plate 1> As shown in FIGS. 1 and 2, a plate 1 according to the present invention holds and connects a plurality of adjacent spheres Q to each other. The plate 1 has holes 2 and a pentagonal hole arrangement portion 3, which will be described later. The plate 1 may have a hexagonal hole arrangement portion 4 or a triangular hole arrangement portion 5, which will be described later.

[0019] The shape of plate 1 in a plan view is not particularly limited, but may be, for example, approximately square, approximately rectangular, or other shapes such as approximately hexagonal, approximately triangular, or approximately pentagonal, and the corners of plate 1 may be rounded or chamfered (corners may be cut off). The size of plate 1 is not particularly limited, but for example, if plate 1 is approximately square in a plan view, the length of each side may be 3 cm or more and 30 cm or less, preferably 4 cm or more and 25 cm or less, and more preferably 5 cm or more and 20 cm or less (e.g., approximately 10 cm). When viewed from the side, plate 1 may be a single flat plate, or each side (end) of plate 1 may have an upright portion that is erected at an angle of approximately 90° or the like (in other words, plate 1 may be configured in a tray shape). The thickness of the plate 1 is not particularly limited, and may be, for example, 0.1 mm to 10.0 mm, preferably 0.2 mm to 8.0 mm, and more preferably 0.5 mm to 5.0 mm (eg, about 1.0 mm).

[0020] <hole 2> As shown in FIGS. 1 and 2, the hole 2 is for holding a sphere Q. The hole 2 may be a through hole or may have a bottom. The shape of the hole 2 in a plan view is not particularly limited, and may be, for example, a substantially circular shape, or may be a substantially square shape, a substantially regular hexagonal shape, a substantially regular triangular shape, a substantially regular pentagonal shape, or the like. The size of hole 2 is not particularly limited, but for example, when hole 2 is approximately circular in a planar view, diameter 2D of hole 2 may be 1 mm or more and 10 mm or less, more preferably 2 mm or more and 8 mm or less, and even more preferably 3 mm or more and 6 mm or less (4 mm, 5 mm, etc.). To explain the diameter 2D of the hole 2 in more detail, when the hole 2 is a through hole, the diameter 2D of the hole 2 will be smaller than the diameter QD of the sphere Q; otherwise, when the hole 2 has a bottom, the diameter 2D of the hole 2 may be smaller than, approximately the same as, or larger than the diameter QD of the sphere Q. The shape of hole 2 in a side cross-sectional view is not particularly limited, and when hole 2 is a through hole, it may be, for example, approximately rectangular or square, or the diameter 2D of hole 2 may change in the through-hole direction (for example, the diameter 2D of hole 2 may be larger or smaller halfway through the through-hole direction), and when hole 2 has a bottom, it may be, for example, approximately rectangular, square, or arc-shaped.

[0021] Regarding the depth of hole 2, when hole 2 is a through hole, the depth of hole 2 (i.e., the length in the through direction) is approximately the same as the thickness of plate 1, and when hole 2 is bottomed, the depth of hole 2 is smaller (shallower) than the thickness of plate 1, and the value is not particularly limited, and may be, for example, 0.1 mm or more and 9.0 mm or less, preferably 0.2 mm or more and 7.0 mm or less, and more preferably 0.5 mm or more and 4.0 mm or less. A plurality of holes 2 are provided in one plate 1, and the number is not particularly limited, but may be, for example, 10 to 4000, preferably 50 to 2000, and more preferably 100 to 1000 (e.g., 543).

[0022] <Pentagonal hole arrangement section 3, distance between hole centers 3L> As shown in FIGS. 1 and 2, the pentagonal hole arrangement portion 3 is a portion that holds the spheres Q and in which the above-mentioned holes 2 are arranged in a pentagonal shape in a plan view. In this invention, "arranged in a pentagonal shape when viewed from above" includes not only a case where the elements are arranged in a strictly regular pentagonal shape, but also a case where the elements are arranged in a pentagonal shape with each side being a different length (a pentagonal shape that is not a regular pentagon) and a case where the elements are arranged in a pentagonal shape with each exterior angle different from 72° (again, a pentagonal shape that is not a regular pentagon). The number of pentagonal hole arrangements 3 in one plate 1 is not particularly limited, but may be, for example, 1 to 50, preferably 2 to 40, and more preferably 3 to 30 (e.g., 14). The pentagonal hole arrangement portions 3 may be provided in one plate 1 at predetermined intervals substantially along the vertical or horizontal direction thereof.

[0023] As shown in Figures 1 and 2, the distance 3L between the centers of two adjacent holes 2 in a pentagonal hole arrangement portion 3 (the distance between the hole centers corresponding to the sides of the pentagon of the pentagonal hole arrangement portion 3) is not particularly limited, and may be, for example, 2 mm or more and 10 mm or less, more preferably 3 mm or more and 8 mm or less, and even more preferably 4 mm or more and 6 mm or less (e.g., approximately 5 mm). The center-to-center distance 3L in the pentagonal hole arrangement portion 3 may be substantially the same as the diameter QD of the sphere Q (3L≈QD).

[0024] <Hexagonal hole arrangement section 4, distance between hole centers 4L, etc.> As shown in FIGS. 1 and 2, the hexagonal hole arrangement portion 4 is a portion in which the above-mentioned holes 2, which hold the spheres Q, are arranged in a hexagonal shape in a plan view. In this invention, "arranged in a hexagonal shape when viewed from above" includes not only a case where the elements are arranged in a strictly regular hexagonal shape, but also a case where the elements are arranged in a hexagonal shape with each side having a different length (a hexagonal shape that is not a regular hexagon) and a case where the elements are arranged in a hexagonal shape with each exterior angle slightly different from 60° (again, a hexagonal shape that is not a regular hexagon). The number of hexagonal hole arrangement portions 4 in one plate 1 is not particularly limited, and may be, for example, 1 to 1000, preferably 10 to 800, and more preferably 100 to 600 (e.g., 389). Furthermore, the number of hexagonal hole arrangement portions 4 in one plate 1 may be more than the number of pentagonal hole arrangement portions 3 described above, but may also be approximately the same as or less than the number of pentagonal hole arrangement portions 3. The hexagonal hole arrangement portion 4 may be continuously present in a portion in which many holes 2 are arranged in a staggered (alternate) pattern in one plate 1, in which case the hole 2 is present in an approximately central position surrounded by each of the hexagonal hole arrangement portions 4. Alternatively, the hexagonal hole arrangement portions 4 may be provided separately at predetermined intervals in one plate 1 substantially along the vertical or horizontal direction thereof.

[0025] As shown in Figures 1 and 2, the distance 4L between the centers of two adjacent holes 2 in a hexagonal hole arrangement portion 4 (the distance between the hole centers corresponding to the sides of the hexagon of the hexagonal hole arrangement portion 4) is not particularly limited, and may be, for example, 2 mm or more and 10 mm or less, more preferably 3 mm or more and 8 mm or less, and even more preferably 4 mm or more and 6 mm or less (e.g., about 5 mm). The center-to-center distance 4L in the hexagonal hole arrangement portion 4 may also be approximately the same as the diameter QD of the sphere Q (4L ≒ QD); in other words, it can be said that the center-to-center distance 4L in the hexagonal hole arrangement portion 4 is approximately the same as the center-to-center distance 3L in the above-mentioned pentagonal hole arrangement portion 3 (4L ≒ 3L). The hexagonal hole arrangement portion 4 may have a portion adjacent to the above-mentioned pentagonal hole arrangement portion 3 (in other words, the plate 1 may be provided with a pentagonal-hexagonal hole arrangement portion 6 in which the pentagonal hole arrangement portion 3 and the hexagonal hole arrangement portion 4 are adjacent to each other), and the hexagonal hole arrangement portion 4 may share at least some of the holes 2 with the pentagonal hole arrangement portion 3 (in one pentagonal-hexagonal hole arrangement portion 6, at least some of the holes 2 may be included in the pentagonal hole arrangement portion 3 and also in the hexagonal hole arrangement portion 4). The number of holes 2 shared by the hexagonal hole arrangement portion 4 and the pentagonal hole arrangement portion 3 is not particularly limited, and may be one or two, for example.

[0026] <Triangular hole arrangement section 5, distance between hole centers 5L, etc.> As shown in FIGS. 1 and 2, the triangular hole arrangement portion 5 is a portion that holds the sphere Q and in which the above-mentioned holes 2 are arranged in a triangular shape in a plan view. In this invention, "arranged in a triangular shape when viewed in a plane" does not only mean an arrangement in a strictly equilateral triangle, but also a arrangement in a triangle shape where each side is of different length (a triangular shape that is not an equilateral triangle), or a triangle where each exterior angle is different from 120° (again, a triangular shape that is not an equilateral triangle). The number of triangular hole arrangement portions 5 in one plate 1 is not particularly limited, and may be, for example, 1 to 50, preferably 2 to 40, and more preferably 3 to 30 (e.g., 14). Furthermore, the number of triangular hole arrangement portions 5 in one plate 1 may be approximately the same as the number of pentagonal hole arrangement portions 3 described above, but may be less or more. Furthermore, the number of triangular hole arrangement portions 5 in one plate 1 may be less than the number of hexagonal hole arrangement portions 4 described above, but may be approximately the same as or more than the number of hexagonal hole arrangement portions 4. The triangular hole arrangements 5 may be provided on one plate 1 at predetermined intervals substantially along the vertical or horizontal direction thereof.

[0027] As shown in Figures 1 and 2, the distance 5L between the centers of two adjacent holes 2 in a triangular hole arrangement portion 5 (the distance between the hole centers corresponding to the sides of the hexagon in the triangular hole arrangement portion 5) is not particularly limited, and may be, for example, 3 mm or more and 15 mm or less, more preferably 4 mm or more and 12 mm or less, and even more preferably 5 mm or more and 9 mm or less (e.g., approximately 7.5 mm). Furthermore, the center-to-center distance 5L in the triangular hole arrangement portion 5 may be longer than the diameter QD of the sphere Q (5L>QD), in other words, it may be longer than the center-to-center distance 3L in the pentagonal hole arrangement portion 3 or the center-to-center distance 4L in the hexagonal hole arrangement portion 4 (5L>3L≒4L).

[0028] The triangular hole arrangement portion 5 may have a portion 7 adjacent to the above-mentioned pentagonal hole arrangement portion 3 (in other words, the plate 1 may be provided with a triangular-pentagonal hole arrangement portion 7 in which the triangular hole arrangement portion 5 and the pentagonal hole arrangement portion 3 are adjacent to each other), and the triangular hole arrangement portion 5 may share at least some of the holes 2 with the pentagonal hole arrangement portion 3 (in one triangular-pentagonal hole arrangement portion 7, at least some of the holes 2 may be included in the triangular hole arrangement portion 5 and also in the pentagonal hole arrangement portion 3). The number of holes 2 shared by the triangular hole arrangement portion 5 and the pentagonal hole arrangement portion 3 may be, for example, one.

[0029] <3D object 10> As shown in FIGS. 3 and 4, the three-dimensional object 10 is composed of a number of spheres Q connected together. The three-dimensional object 10 has a pentagonal sphere connection portion 13, which will be described later. The three-dimensional object 10 may have hexagonal sphere connection parts 14 or triangular pyramid sphere connection parts 15, which will be described later. In addition, the three-dimensional object 10 may have pentagonal / hexagonal sphere connection parts 16, which will be described later.

[0030] The shape of the three-dimensional object 10 is not particularly limited, but it may be, for example, a three-dimensional object showing a molecular structure formed by regarding one sphere Q as one atom, or, more specifically, it may be a polymer compound having a pentagonal sphere connection part 13 described later that can be regarded as a ring arrangement (heterocycle), a biopolymer compound such as deoxyribonucleic acid (DNA), polypeptide, polysaccharide, or a synthetic polymer compound. Note that the transparent rod-shaped body that supports the three-dimensional object 10 is located at the upper left of FIG. 3. The number of spheres Q connected (used) in one three-dimensional object 10 is not particularly limited, but may be, for example, 10 to 1,000,000, preferably 100 to 500,000, and more preferably 1,000 to 100,000. In addition, in the three-dimensional object 10, the connections between the spheres Q may be made by dissolving the spheres Q themselves and connecting (adhering) the spheres Q to each other, or alternatively, the spheres Q may be connected to each other with an adhesive.

[0031] <Pentagonal sphere joint 13> 3 and 4(a), the pentagonal sphere connection part 13 is a part where the spheres Q are connected in a pentagonal shape. In the pentagonal sphere connection part 13, of the five spheres Q connected in a pentagonal shape, two spheres Q adjacent to each other on the sides of the pentagon are directly connected (on the other hand, there is no sphere Q in the approximate center surrounded by the pentagonal sphere connection part 13, and the pentagonal sphere connection part 13 is in the shape of a ring). In the present invention, "connected in a pentagonal shape" does not only refer to a connection in a strictly regular pentagonal shape, but also includes a connection in a pentagonal shape whose sides are of different lengths (a pentagonal shape that is not a regular pentagon) and a pentagonal shape whose exterior angles are different from 72° (again, a pentagonal shape that is not a regular pentagon). The number of pentagonal sphere connecting parts 13 in one three-dimensional object 10 is not particularly limited, but may be, for example, 1 to 1000, preferably 5 to 800, and more preferably 10 to 500.

[0032] <Hexagonal sphere connection part 14 etc.> 3, the hexagonal sphere connection part 14 is a part where the spheres Q are connected in a hexagonal shape. Note that, in the hexagonal sphere connection part 14, of the six spheres Q connected in a hexagonal shape, two spheres Q adjacent to each other on the sides of the hexagon are directly connected (on the other hand, there is no sphere Q in the approximate center surrounded by the hexagonal sphere connection part 14, and the hexagonal sphere connection part 14 is also annular). In the present invention, "connected in a hexagonal shape" does not only refer to a case where the connection is made in a strictly regular hexagonal shape, but also includes a case where the connection is made in a hexagonal shape whose sides have different lengths (a hexagonal shape that is not a regular hexagon) and a case where the connection is made in a hexagonal shape whose exterior angles are different from 60° (again, a hexagonal shape that is not a regular hexagon). The number of hexagonal sphere connecting parts 14 in one three-dimensional object 10 is not particularly limited, and may be, for example, 1 to 1000, preferably 5 to 800, and more preferably 10 to 500. Furthermore, the number of hexagonal sphere connecting parts 14 in one three-dimensional object 10 may be less than the number of pentagonal sphere connecting parts 13 described above, but may also be approximately the same as or greater than the number of pentagonal sphere connecting parts 13.

[0033] The hexagonal sphere connecting portion 14 may have a portion 16 adjacent to the pentagonal sphere connecting portion 13 described above (in other words, the three-dimensional object 10 may have a pentagonal-hexagonal sphere connecting portion 16 where the pentagonal sphere connecting portion 13 and the hexagonal sphere connecting portion 14 are adjacent to each other), and the hexagonal sphere connecting portion 14 may share at least a portion of the spheres Q with the pentagonal sphere connecting portion 13 (in one pentagonal-hexagonal sphere connecting portion 16, at least a portion of the spheres Q may be included in both the pentagonal sphere connecting portion 13 and the hexagonal sphere connecting portion 14). The number of spheres Q shared by the hexagonal sphere connection portion 14 and the pentagonal sphere connection portion 13 is not particularly limited, and may be one or two, for example.

[0034] <Triangular pyramid sphere connection part 15 etc.> 3 and 4(b), the triangular pyramid sphere connection part 15 is a part where the spheres Q are connected in a triangular pyramid (tetrahedron) shape. Note that in the triangular pyramid sphere connection part 15, of the five spheres Q connected in a triangular pyramid shape, the four spheres Q corresponding to each vertex are directly connected to one sphere Q located approximately in the center, but the four spheres Q corresponding to each vertex are not directly connected to each other. In the present invention, "connected in a triangular pyramid shape" does not only refer to a connection in a strictly regular triangular pyramid shape, but also includes a connection in a triangular pyramid shape in which the sides are of different lengths (a triangular pyramid shape that is not a regular triangular pyramid) and a connection in which the exterior angles are different from 120° (again, a triangular pyramid shape that is not a regular triangular pyramid). The number of triangular pyramidal sphere connecting parts 15 in one three-dimensional object 10 is not particularly limited, and may be, for example, 1 to 1000, preferably 5 to 800, and more preferably 10 to 500. The number of triangular pyramidal sphere connecting parts 15 in one three-dimensional object 10 may be less than the number of the pentagonal sphere connecting parts 13 described above, or may be approximately the same as or greater than the number of the pentagonal sphere connecting parts 13. The number of triangular pyramidal sphere connecting parts 15 in one three-dimensional object 10 may be approximately the same as the number of the hexagonal sphere connecting parts 14 described above, or may be less than or greater than the number of the hexagonal sphere connecting parts 14.

[0035] The triangular pyramidal sphere connecting portions 15 may have a portion adjacent to the above-mentioned pentagonal sphere connecting portions 13 (in other words, the three-dimensional object 10 may have triangular pyramidal-pentagonal sphere connecting portions 17 in which the triangular pyramidal sphere connecting portions 15 and the pentagonal sphere connecting portions 13 are adjacent to each other), and the triangular pyramidal sphere connecting portions 15 may share at least a portion of the spheres Q with the pentagonal sphere connecting portions 13 (in one triangular pyramidal-pentagonal sphere connecting portion 17, at least a portion of the spheres Q may be included in the triangular pyramidal sphere connecting portion 15 and also in the pentagonal sphere connecting portion 13), or conversely, they may not share the spheres Q (in one triangular pyramidal-pentagonal sphere connecting portion 17, there may not be a sphere Q that is included in the triangular pyramidal sphere connecting portion 15 and also in the pentagonal sphere connecting portion 13). When a sphere Q is shared between a triangular pyramidal sphere connection part 15 and a pentagonal sphere connection part 13, the number of the shared spheres Q may be one, etc. Furthermore, the triangular pyramidal sphere connection part 15 and the pentagonal sphere connection part 13 in the triangular pyramidal-pentagonal sphere connection part 17 may be in a twisted state (a state in which the plane where the spheres Q corresponding to the three vertices of the triangular pyramidal sphere connection part 15 are in contact and the plane where the five spheres Q of the pentagonal sphere connection part 13 are in contact are not the same plane).

[0036] <Method of manufacturing three-dimensional object 10> As shown in FIGS. 5 to 7, the above-described method for manufacturing the three-dimensional object 10 (hereinafter, also referred to as "the manufacturing method") includes at least a pentagonal sphere connecting step P, which will be described later. In addition to the pentagonal sphere connecting step P, the manufacturing method may also include a hexagonal sphere connecting step P1-2, a triangular pyramidal sphere connecting step P1-3, an entire connecting step P2, and the like, which will be described later. If the manufacturing method includes a hexagonal sphere connecting process P1-2 etc. in addition to the pentagonal sphere connecting process P, the pentagonal sphere connecting process P is a process that can be carried out in parallel with the hexagonal sphere connecting process P1-2 and the triangular pyramidal sphere connecting process P1-3, and the pentagonal sphere connecting process is designated by the symbol P1-1. Here, in the manufacturing method, if it comprises the pentagonal sphere connecting step P1-1 and the whole connecting step P2, it is considered as the first embodiment, if it comprises the pentagonal sphere connecting step P1-1, the hexagonal sphere connecting step P1-2 and the whole connecting step P2, it is considered as the second embodiment (the pentagonal sphere connecting step P1-1 and the hexagonal sphere connecting step P1-2 can be performed in any order, such as in parallel or in any order, but in FIG. 5(b), the pentagonal sphere connecting step P1-1 is shown in the order of the hexagonal sphere connecting step P1-2), if it comprises the pentagonal sphere connecting step P1-1, the triangular pyramidal sphere connecting step P1-3 and the whole connecting step P2, it is considered as the third embodiment (the pentagonal sphere connecting step P1-1 and ...2 can be performed in any order, such as in parallel or in any order). For step P1-3, the order in which one is performed first or in parallel does not matter, but in FIG. 5(c) they are shown in the order of pentagonal sphere connecting step P1-1 → triangular pyramidal sphere connecting step P1-3), and when it includes the pentagonal sphere connecting step P1-1, the hexagonal sphere connecting step P1-2, the triangular pyramidal sphere connecting step P1-3 and the whole connecting step P2, this is considered to be the fourth embodiment (the order in which the pentagonal sphere connecting step P1-1, the hexagonal sphere connecting step P1-2 and the triangular pyramidal sphere connecting step P1-3 are shown in the order of pentagonal sphere connecting step P1-1 → hexagonal sphere connecting step P1-2 → triangular pyramidal sphere connecting step P1-3 does not matter, but in FIG. 5(d) they are shown in the order of pentagonal sphere connecting step P1-1 → hexagonal sphere connecting step P1-2 → triangular pyramidal sphere connecting step P1-3).

[0037] In each of the connection steps P1-1 to P1-3 and P2 of the manufacturing method described later, the connection between the spheres Q may be performed by dissolving the spheres Q themselves by pouring a solvent such as water on them, and connecting (adhering) the spheres Q to each other (FIG. 3 and FIG. 4(b) show that the spheres Q themselves have been dissolved), or alternatively, the spheres Q may be connected to each other with an adhesive. In each of the connection steps P1-1 to P1-3 and P2, tweezers for holding the spheres Q, a device for supplying the spheres Q one by one, a spray for spraying a solvent such as water, or the like may be used. Furthermore, in each of the connection steps P1-1 to P1-3 and P2 of the manufacturing method described later, the spheres Q may be dried (left) in a connected state, and the drying time (left-standing time) is not particularly limited, but may be, for example, 5 minutes or more and 10 hours or less, preferably 10 minutes or more and 5 hours or less, and more preferably 30 minutes or more and 3 hours or less (e.g., 1 hour). In addition, in this manufacturing method, such drying (leaving) may be a separate process from each of the connecting steps P1-1 to 3 and P2 (i.e., a drying process (leaving) process), and such a drying process may be performed immediately after each of the connecting steps P1-1 to 3 and P2, or between each of the connecting steps P1-1 to 3 and P2.

[0038] <Pentagonal sphere connection process P (P1-1)> As shown in Figures 5 and 6, the pentagonal sphere connecting process P (P1-1) is a process of connecting multiple spheres Q at the pentagonal sphere connecting portion 13 of the above-mentioned three-dimensional object 10 using the pentagonal hole arrangement portion 3 of the above-mentioned plate 1. In the present invention, "using the pentagonal hole arrangement portion 3 of the plate 1" means that while each sphere Q in the pentagonal sphere connection portion 13 is held in each hole 2 in the pentagonal hole arrangement portion 3 of the plate 1, a connection is made between two adjacent spheres Q on the pentagonal sides of the pentagonal hole arrangement portion 3 by, for example, melting the sphere Q itself. In this pentagonal sphere connecting process P1-1(P), the relationship between the diameter QD of the sphere Q, the diameter 2D of the hole 2 in the pentagonal hole arrangement portion 3, and the distance 3L between the centers of two adjacent holes 2 on the pentagonal sides of the pentagonal hole arrangement portion 3 is not particularly limited, but may be, for example, 3L ≒ QD > 2D.

[0039] <Hexagonal sphere connection process P1-2 etc.> As shown in FIG. 5, the hexagonal sphere connecting process P1-2 is a process of connecting a plurality of spheres Q at the hexagonal sphere connecting portion 14 of the three-dimensional object 10 described above using the hexagonal hole arrangement portion 4 of the plate 1 described above. In the present invention, "using the hexagonal hole arrangement portion 4 of the plate 1" means that while each sphere Q in the hexagonal sphere connection portion 14 is held in each hole 2 in the hexagonal hole arrangement portion 4 of the plate 1, a connection is made between two adjacent spheres Q on the hexagonal sides of the hexagonal hole arrangement portion 4 by, for example, melting the spheres Q themselves. In this hexagonal sphere connecting process P1-2, the relationship between the diameter QD of the sphere Q, the diameter 2D of the hole 2 in the hexagonal hole arrangement portion 4, and the distance 4L between the centers of two adjacent holes 2 on the hexagonal sides of the hexagonal hole arrangement portion 4 is not particularly limited, but may be, for example, 4L ≒ QD > 2D.

[0040] Furthermore, this manufacturing method may also include a pentagonal-hexagonal sphere connecting process P1-12 in which a pentagonal-hexagonal hole arrangement portion 6 in which a pentagonal hole arrangement portion 3 and a hexagonal hole arrangement portion 4 are adjacent to each other in the above-mentioned plate 1 is used to connect a plurality of spheres Q at a pentagonal-hexagonal sphere connection portion 16 in which a pentagonal sphere connection portion 13 and a hexagonal sphere connection portion 14 are adjacent to each other in the above-mentioned three-dimensional object 10. In the present invention, "using the pentagonal-hexagonal hole arrangement portion 6 of the plate 1" means that while each sphere Q in the pentagonal-hexagonal sphere connection portion 16 is held in each hole 2 in the pentagonal-hexagonal hole arrangement portion 6 of the plate 1, a connection is made between two adjacent spheres Q of the multiple spheres Q in the pentagonal-hexagonal sphere connection portion 16 along the sides of the pentagon or hexagon of the pentagonal-hexagonal sphere connection portion 16 by, for example, melting the sphere Q itself. In this pentagonal-hexagonal sphere connecting process P1-12, the relationship between the diameter QD of the sphere Q, the diameter 2D of the hole 2 in the pentagonal-hexagonal hole arrangement portion 6, and the distances 3L and 4L between the centers of two adjacent holes 2 on the sides of the pentagon or hexagon in the pentagonal-hexagonal hole arrangement portion 6 is not particularly limited, but may be, for example, QD ≒ 3L ≒ 4L > 2D.

[0041] <Triangular pyramid sphere connection process P1-3 etc.> As shown in Figures 5 and 7, the triangular pyramidal sphere connecting process P1-3 is a process of connecting multiple spheres Q at the triangular pyramidal sphere connecting portion 15 of the above-mentioned three-dimensional object 10 using the triangular hole arrangement portion 5 of the above-mentioned plate 1. In the present invention, "using the triangular hole arrangement portion 5 of the plate 1" means that each sphere Q in the triangular pyramidal sphere connection portion 15 is held in each hole 2 in the triangular hole arrangement portion 5 of the plate 1, and another sphere Q is placed and held approximately in the center of the three held spheres Q, and then the sphere Q itself is melted, for example, to connect the spheres Q at the three vertices of the multiple spheres Q in the triangular pyramidal sphere connection portion 15 with one approximately central sphere Q (see the three black spheres Q and one white sphere Q in Figure 7). Furthermore, in the triangular pyramidal sphere connecting process P1-3, while (or after) connecting the spheres Q corresponding to the three vertices of the multiple spheres Q in the triangular pyramidal sphere connecting portion 15 to one approximately central sphere Q, a connection may be made between the sphere Q corresponding to the fourth vertex and one approximately central sphere Q. In this triangular pyramidal sphere connecting step P1-3, the relationship between the diameter QD of the sphere Q, the diameter 2D of the hole 2 in the triangular hole arrangement section 5, and the distance 5L between the centers of two adjacent holes 2 on the sides of the triangle in the triangular hole arrangement section 5 is not particularly limited, and may be, for example, 5L>QD>2D. Note that in the triangular pyramidal sphere connecting step P1-3, when connecting the spheres Q at the three vertices and one approximately central sphere Q as shown in Fig. 7, the upper limit of 5L is "{(QD / 2) x √3} x 2", which is the limit at which the spheres Q at each vertex and the approximately central sphere Q can reach each other. For example, when QD = 5 mm and 2D = 4 mm, the upper limit of 5L is about 8.6 mm.

[0042] Furthermore, this manufacturing method may also include a triangular pyramid-pentagonal sphere connecting process P1-13 in which a triangular-pentagonal sphere connection portion 17 in which a triangular hole arrangement portion 5 and a pentagonal hole arrangement portion 3 are adjacent to each other in the above-mentioned plate 1 is used to connect a plurality of spheres Q at a triangular pyramid-pentagonal sphere connection portion 17 in which a triangular pyramid-sphere connection portion 15 and a pentagonal sphere connection portion 13 are adjacent to each other in the above-mentioned three-dimensional object 10. In the present invention, "using the triangular-pentagonal hole arrangement portion 7 of the plate 1" means that each sphere Q in the triangular pyramid-pentagonal sphere connection portion 17 is held in each hole 2 in the triangular-pentagonal hole arrangement portion 7 of the plate 1, or another sphere Q is placed and held approximately in the center of the three held spheres Q, and the sphere Q itself is melted, etc., to connect between the three spheres Q corresponding to each vertex of the triangular pyramid-pentagonal sphere connection portion 15 and the one sphere Q located approximately in the center, among the multiple spheres Q in the triangular pyramid-pentagonal sphere connection portion 17, or between two adjacent spheres Q on the sides of the pentagon of the pentagonal sphere connection portion 13. In this triangular pyramid / pentagonal sphere connecting process P1-13, the relationship between the diameter QD of the sphere Q, the diameter 2D of the hole 2 in the triangular / pentagonal hole arrangement portion 7, and the distances 5L and 3L between the centers of two adjacent holes 2 on the sides of the triangle or pentagon in the triangular / pentagonal hole arrangement portion 7 is not particularly limited, but may be, for example, 5L>QD≒3L>2D.

[0043] <Overall connection process P2> As shown in FIG. 5, the overall connecting process P2 is a process for connecting together the pentagonal sphere connecting portions 13, hexagonal sphere connecting portions 14, triangular pyramidal sphere connecting portions 15, etc., which were connected in the above-mentioned pentagonal sphere connecting process P (P1-1), hexagonal sphere connecting process P1-2, triangular pyramidal sphere connecting process P1-3, etc. When connecting the pentagonal sphere connecting parts 13 etc. to each other in the overall connecting step P2, the pentagonal sphere connecting parts 13 etc. may be in a twisted state, and in this case, it is not necessary to use the plate 1 for connection. Additionally, in the overall connecting step P2, one or more spheres Q may be connected to the pentagonal sphere connecting portion 13 or the like, or one or more spheres Q may be connected to each other.

[0044] When connecting one or more spheres Q to the pentagonal sphere connection part 13 etc. in the overall connecting step P2, the pentagonal sphere connecting step P1-1 etc. may use the pentagonal hole arrangement part 3 of the plate 1 to connect the multiple spheres Q at the pentagonal sphere connection part 13 etc., and then connect the one or more spheres Q to the pentagonal sphere connection part 13 etc. using one or more adjacent holes 2 among the holes 2 of the hexagonal hole arrangement part 4 etc. adjacent to the pentagonal hole arrangement part 3 etc. In this case, it can be said that the strength of the connection between the pentagonal sphere connection part 13 etc. and the one or more spheres Q is improved compared to when the plate 1 is not used. Furthermore, when connecting one or more spheres Q to each other in the overall connecting step P2, any one hole 2 or any adjacent holes 2 among the holes 2 in the hexagonal hole arrangement portion 4 of the plate 1 may be used to connect one or more spheres Q to each other. In this case, it can also be said that the strength of the connection between one or more spheres Q is improved compared to when the plate 1 is not used. In the overall connecting process P2, the connection of pentagonal sphere connecting portions 13 etc. to one or more spheres Q, and the connection of one or more spheres Q to each other may be performed once or multiple times.

[0045] <Other> The present invention is not limited to the above-described embodiment. The individual components of the plate 1, the three-dimensional object 10, the manufacturing method of the three-dimensional object 10, and the overall structure, shape, dimensions, etc. can be appropriately changed in accordance with the spirit of the present invention. The plate 1 does not have to have a hexagonal hole arrangement portion 4 or a triangular hole arrangement portion 5, and even if the plate 1 has a hexagonal hole arrangement portion 4 or a triangular hole arrangement portion 5, the plate 1 does not have to have adjacent portions such as a pentagonal-hexagonal hole arrangement portion 6 or a triangular-pentagonal hole arrangement portion 7. In addition, the plate 1 may have a portion where the triangular hole arrangement portion 5 is adjacent to a hexagonal hole arrangement portion 4 (in other words, the plate 1 may have a triangular-hexagonal hole arrangement portion where the triangular hole arrangement portion 5 and the hexagonal hole arrangement portion 4 are adjacent to each other), and in this case, the triangular hole arrangement portion 5 may share at least some of the holes 2 with the hexagonal hole arrangement portion 4 (in one triangular-hexagonal hole arrangement portion, at least some of the holes 2 may be included in the triangular hole arrangement portion 5 and also in the hexagonal hole arrangement portion 4). The number of holes 2 shared by the triangular hole arrangement portion 5 and the hexagonal hole arrangement portion 4 is not particularly limited, and may be one or two, for example.

[0046] In addition to the pentagonal hole arrangement portion 3, hexagonal hole arrangement portion 4, triangular hole arrangement portion 5, etc., the plate 1 may have a square hole arrangement portion in which the holes 2 for holding the spheres Q are arranged in a square shape when viewed in a plan view, a heptagonal hole arrangement portion in which the holes are arranged in a heptagonal shape, an octagonal hole arrangement portion in which the holes are arranged in an octagonal shape, or a hole arrangement portion in which the holes are arranged in a nonagon or more shape, and these hole arrangement portions may or may not be adjacent to each other. When the plate 1 has adjacent portions such as pentagonal / hexagonal hole arrangement portions 6, the adjacent hole arrangement portions (such as the pentagonal hole arrangement portion 3 and the hexagonal hole arrangement portion 4) do not have to share holes 2 (there is no hole 2 that is included in one hole arrangement portion and also in the other hole arrangement portion). Furthermore, the distance between the centers of two adjacent holes 2 in a square hole arrangement section may be longer than the distance 3L between the centers of two adjacent holes 2 in a pentagonal hole arrangement section 3, and the distance between the centers of two adjacent holes 2 in a heptagonal hole arrangement section, an octagonal hole arrangement section, or a hole arrangement section arranged in a nonagon or more shape may be approximately the same as the distance 3L between the centers of two adjacent holes 2 in the pentagonal hole arrangement section 3. Furthermore, when the hexagonal hole arrangement portion 4 is continuously present in a portion of a single plate 1 in which many holes 2 are arranged in a staggered pattern, the entire continuously present hexagonal hole arrangement portion 4 can also be said to be a staggered portion 4'.

[0047] Plate 1 may have upright portions on each side (each end) at an angle of approximately 90° or the like (i.e., plate 1 may have a tray-like configuration), in which case the thickness of plate 1 may be, for example, 1 mm or more and 10 mm or less, preferably 2 mm or more and 8 mm or less, and more preferably 3 mm or more and 6 mm (e.g., approximately 5.0 mm). The erection direction of the erect portion of the plate 1 may be, for example, the opening direction (or the front surface side) of the above-mentioned hole 2 if it has a bottom, or conversely, the direction in which the bottomed hole 2 does not open (the back surface side). The back side of plate 1 may have raised streaks, and the planar shape of the streaks may be, for example, two diagonal lines or an approximately circular shape centered on the intersection of the two diagonal streaks, provided that the planar shape of plate 1 is approximately square. The material of plate 1 is not particularly limited, and may be, for example, a synthetic resin such as polystyrene (PS) resin, polyolefin resin such as acrylonitrile-butadiene-styrene copolymer (ABS) resin, polypropylene (PP) resin, polyethylene (PE) resin, polyacetal (POM) resin, polyamide (PA) resin, polycarbonate (PC) resin, or wood, paper, metal, or a combination of these. The color of the plate 1 is not particularly limited, and may be gray, black, white, red, blue, yellow, or the like, or may be translucent, transparent, or opaque.

[0048] The three-dimensional object 10 does not have to have a hexagonal sphere connecting portion 14 or a triangular pyramidal sphere connecting portion 15, and even if the three-dimensional object 10 has a hexagonal sphere connecting portion 14 or a triangular pyramidal sphere connecting portion 15, the three-dimensional object 10 does not have to have the adjacent portions such as a pentagonal-hexagonal sphere connecting portion 16 or a triangular pyramidal-pentagonal sphere connecting portion 17. In addition, the three-dimensional object 10 may have a portion where a triangular pyramidal sphere connection portion 15 is adjacent to a hexagonal sphere connection portion 14 (in other words, the three-dimensional object 10 may have a triangular pyramidal-hexagonal sphere connection portion where a triangular pyramidal sphere connection portion 15 and a hexagonal sphere connection portion 14 are adjacent to each other), and in this case, the triangular pyramidal sphere connection portion 15 may share at least a portion of the spheres Q with the hexagonal sphere connection portion 14 (in one triangular pyramidal-hexagonal sphere connection portion, at least a portion of the spheres Q may be included in the triangular pyramidal sphere connection portion 15 and also in the hexagonal sphere connection portion 14). The number of spheres Q shared by the triangular pyramidal sphere connection portion 15 and the hexagonal sphere connection portion 14 is not particularly limited, and may be one or two, for example.

[0049] In addition to the pentagonal sphere connection parts 13, hexagonal sphere connection parts 14, triangular pyramidal sphere connection parts 15, etc., the three-dimensional object 10 may have square sphere connection parts where the spheres Q are connected in a square shape, heptagonal sphere connection parts where the spheres are connected in a heptagonal shape, octagonal sphere connection parts where the spheres are connected in an octagonal shape, or sphere connection parts where the spheres are connected in a nonagon or more shape, and these sphere connection parts may or may not be adjacent to each other. When a three-dimensional object 10 has adjacent portions such as pentagonal and hexagonal sphere connection parts 16, adjacent sphere connection parts (such as pentagonal sphere connection part 13 and hexagonal sphere connection part 14) do not have to share a sphere Q (there is no sphere Q that is included in one sphere connection part and also in the other sphere connection part).

[0050] In the manufacturing method of the three-dimensional object 10, the connections between the spheres Q in each of the above-mentioned connection steps P1-1 to P1-3 and P2 may be made by inserting an approximately linear or rod-shaped body into each sphere Q to connect them, or in the case of annular sphere connection parts such as the pentagonal sphere connection part 13 and the hexagonal sphere connection part 14, a single approximately linear or string-shaped body may be inserted in a ring shape to connect all the spheres in each sphere connection part. In addition, when connecting the spheres Q with an adhesive, the material of the adhesive is not particularly limited, but may be, for example, an epoxy adhesive, an instant adhesive (cyanoacrylate adhesive), a silicone adhesive, etc. This manufacturing method does not have to include the hexagonal sphere connecting step P1-2 or the triangular pyramidal sphere connecting step P1-3. Even if the manufacturing method includes the hexagonal sphere connecting step P1-2 or the triangular pyramidal sphere connecting step P1-3, the manufacturing method does not have to include the pentagonal-hexagonal sphere connecting step P1-12 for connecting multiple spheres Q at adjacent pentagonal-hexagonal sphere connecting portion 16, or the triangular pyramidal-pentagonal sphere connecting step P1-13 for connecting multiple spheres Q at adjacent triangular pyramidal-pentagonal sphere connecting portion 17.

[0051] In addition, the manufacturing method may include a triangular-hexagonal sphere connection step of connecting a plurality of spheres Q at a triangular-hexagonal sphere connection portion in which a triangular pyramidal sphere connection portion 15 and a hexagonal sphere connection portion 14 are adjacent to each other in the above-mentioned three-dimensional object 10, using a triangular-hexagonal hole arrangement portion in which a triangular hole arrangement portion 5 and a hexagonal hole arrangement portion 4 are adjacent to each other in the above-mentioned plate 1. In the present invention, "using the triangular / hexagonal hole arrangement portion of plate 1" means that each sphere Q in the triangular pyramid-hexagonal sphere connection portion is held in each hole 2 in the triangular / hexagonal hole arrangement portion of plate 1, or another sphere Q is placed and held approximately in the center of the three held spheres Q, and the sphere Q itself is melted, etc., to connect between the three spheres Q corresponding to each vertex of the triangular pyramid-hexagonal sphere connection portion 15 and the one sphere Q located approximately in the center, or between two adjacent spheres Q on the hexagonal sides of the hexagonal sphere connection portion 14, among the multiple spheres Q in the triangular pyramid-hexagonal sphere connection portion. In this triangular pyramid / hexagonal sphere connecting process, the relationship between the diameter QD of the sphere Q, the diameter 2D of the hole 2 in the triangular / hexagonal hole arrangement portion, and the distances 5L and 4L between the centers of two adjacent holes 2 on the sides of the triangle or hexagon in the triangular / hexagonal hole arrangement portion is not particularly limited, but may be, for example, 5L>QD≒4L>2D.

[0052] In addition to the pentagonal sphere connecting step P1-1, the hexagonal sphere connecting step P1-2, the triangular pyramidal sphere connecting step P1-3, etc., when the plate 1 has a square hole arrangement portion in which the holes 2 for holding the spheres Q are arranged in a square shape in a plan view, a heptagonal hole arrangement portion arranged in a heptagonal shape, an octagonal hole arrangement portion arranged in an octagonal shape, or a hole arrangement portion arranged in a nonagon or more shape, the manufacturing method may include a square sphere connecting step, a heptagonal sphere connecting step, an octagonal sphere connecting step, and a nonagon or more sphere connecting step in which the spheres Q are connected in a square shape, a heptagonal sphere connecting portion connected in a heptagonal shape, an octagonal sphere connecting portion connected in an octagonal shape, or a sphere connecting portion connected in a nonagon or more shape, by using these square hole arrangement portions of the plate 1. In addition, the manufacturing method may include a sphere connecting step in which a portion of plate 1 where each hole arrangement portion is adjacent is used to connect multiple spheres Q in a portion where each sphere connection portion is adjacent, or conversely, it may not include such a step. If the manufacturing method includes a sphere connecting step in which the hole arrangement portions of plate 1 are adjacent to each other to connect a plurality of spheres Q at adjacent portions of the sphere connection portions, the step connects a plurality of spheres Q, and adjacent sphere connection portions (such as pentagonal sphere connection portion 13 and hexagonal sphere connection portion 14) do not have to share a sphere Q (there is no sphere Q that is included in one sphere connection portion and also in the other sphere connection portion). In addition to the first to fourth embodiments described above, the manufacturing method may also include performing at least the pentagonal sphere connecting step P1-1 and the entire connecting step P2 once, and then performing each of the sphere connecting steps P1-1 to P1-3 again, and then performing the entire connecting step P2. In this way, each of the connecting steps P1-1 to P1-3 and P2 may be performed once or multiple times. The plate 1 and the three-dimensional object 10 described above, and the sphere Q related to the manufacturing method thereof will be explained in detail below.

[0053] <Sphere Q> As shown in Figures 1 to 7, the sphere Q is held in the hole 2 of the plate 1 described above, and the three-dimensional object 10 described above is composed of multiple objects, and in the manufacturing method for the three-dimensional object 10 described above, the multiple objects are connected using the plate 1. The shape of the sphere Q need not necessarily be strictly spherical, but may be approximately spherical, or may be approximately ellipsoidal having a major axis and a minor axis, or may have irregularities on the surface of the sphere Q. The diameter of the sphere Q is not particularly limited, but for example, if the sphere Q is spherical, it may be 2 mm or more and 10 mm or less, more preferably 3 mm or more and 8 mm or less, and even more preferably 4 mm or more and 6 mm or less (such as about 5 mm). The diameter of the sphere Q may be approximately the same as the distance 3L between the centers of two adjacent holes 2 on a pentagonal side of the pentagonal hole arrangement portion 3 of the plate 1 described above, or the distance 4L between the centers of two adjacent holes 2 on a hexagonal side of the hexagonal hole arrangement portion 4 (QD ≒ 3L ≒ 4L), or may be smaller than the distance 5L between the centers of two adjacent holes 2 on a triangular side of the triangular hole arrangement portion 5 (QD < 5L). Furthermore, the diameters QD of the multiple spheres Q connected in one three-dimensional object 10 may be uniform, or conversely, they may not be uniform (for example, in a triangular pyramid sphere connection part 15, among the five spheres Q connected in a triangular pyramid shape, the diameter QD of one sphere Q located approximately in the center may be larger than the diameters QD of the four spheres Q corresponding to each vertex).

[0054] The material of the sphere Q is not particularly limited, but may be, for example, polyvinyl alcohol (PVAL) resin. In this case, the sphere Q itself can be dissolved by spraying water on it, etc., and the spheres Q can be brought into contact with each other, and then dried (left alone) for a predetermined period of time to connect (bond) the spheres Q to each other. Other examples of the material that may be used include polyacrylamide (PAA) resin, carboxymethyl cellulose (CMC) resin, resol-type polyphenol (PF) resin, polyethylene oxide (PEO) resin, etc. Alternatively, the sphere Q may be a sphere whose entire surface is coated with a resin insoluble in a solvent such as water or an organic solvent, and the like, with an adhesive that is soluble in a solvent such as water or an organic solvent. The color of the sphere Q is not particularly limited, and may be gray, white, red, blue, yellow, or the like, or may be translucent, transparent, or opaque. [Industrial Applicability]

It can also be used to produce synthetic polymer compounds, miniatures composed of multiple connected spheres, models, and the like, regardless of shape. The three-dimensional object of the present invention and the three-dimensional object manufactured by the manufacturing method of the present invention can be used as a three-dimensional object exhibiting a molecular structure in which one sphere is regarded as one atom, in particular as a polymer compound having a cyclic arrangement such as a heterocycle, a biopolymer compound such as deoxyribonucleic acid (DNA), a polypeptide, or a polysaccharide, or as a synthetic polymer compound, or as a miniature or model made up of multiple connected spheres, regardless of shape.
