[0003] Japanese Patent Application Laid-Open No. 2023-076479

[0004] Here, it is required to keep the wiring body in a state where another flat member is overlapped.

[0005] Therefore, an object of the present disclosure is to maintain another flat member superimposed on a wiring body.

[0006] The wiring member of the present disclosure comprises a wiring body including a first sheet and a linear transmission member fixed to the first sheet, and a flat body including a second sheet, wherein a through hole is formed in the second sheet, the linear transmission member has a fixed region and a clamping region, the fixed region is fixed to the first sheet via the through hole, and at least a portion of the second sheet is clamped between the clamping region and the first sheet.

[0007] According to the present disclosure, it is possible to maintain another flat member superimposed on the wiring body.

FIG. 3 is a cross-sectional view taken along line III-III in FIG. 1. FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 1. FIG. 5 is a plan view showing the wiring member. FIG. 6 is a cross-sectional view showing a wiring member according to a modified example. FIG. 7 is a cross-sectional view showing a wiring member according to another modified example.

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described.

[0010] The wiring member of the present disclosure is as follows.

[0011] (1) A wiring member comprising: a wiring body including a first sheet and a linear transmission member fixed to the first sheet; and a flat body including a second sheet, wherein a through hole is formed in the second sheet; the linear transmission member has a fixed region and a clamping region; the fixed region is fixed to the first sheet via the through hole; and at least a portion of the second sheet is sandwiched between the clamping region and the first sheet.

[0012] By fixing the fixing region of the linear transmission member to the first sheet via the through hole, at least a portion of the second sheet is sandwiched between the clamping region of the linear transmission member and the first sheet, thereby fixing the flat body to the wiring body.

[0013] (2) In the wiring member of (1), the surface material of the linear transmission member may have a property such that the peel strength due to fusion to the first sheet is greater than the peel strength due to fusion to the second sheet.

[0014] This allows the linear transmission member to be firmly fixed to the first sheet, which in turn allows the second sheet to be firmly fixed to the wiring body.

[0015] (3) A wiring member according to (1) or (2), wherein the wiring body is a first wiring body including the first sheet and a first linear transmission member as the linear transmission member, and the flat body may be a second wiring body including the second sheet and a second linear transmission member fixed to the second sheet.

[0016] This allows the first wiring body and the second wiring body to be stacked.

[0017] (4) In the wiring member of (3), the second linear transmission member may be located on the same side of the second sheet as the first linear transmission member.

[0018] This allows the first linear transmission member and the second linear transmission member to be disposed on the same side of the second sheet, which contributes to making the wiring member thinner.

[0019] (5) In the wiring member of (3) or (4), the surface material of the second linear transmission member may have a property such that the peel strength due to fusion to the second sheet is greater than the peel strength due to fusion to the first sheet.

[0020] This allows the second linear transmission member to be firmly fixed to the second sheet.

[0021] (6) In the wiring member of (5), the surface material of the first linear transmission member may have a property such that the peel strength due to fusion to the first sheet is greater than the peel strength due to fusion to the second sheet.

[0022] This allows the first linear transmission member to be firmly fixed to the first sheet, and the second linear transmission member to be firmly fixed to the second sheet. Furthermore, by firmly fixing the first linear transmission member to the first sheet via the through-hole, the second sheet of the second wiring body is kept firmly stacked on the first wiring body. Therefore, even if the coating materials of the outermost layers of the first and second linear transmission members are different, each linear transmission member can be firmly fixed to the sheet, and the wiring bodies can be kept stacked.

[0023] (7) In any one of the wiring members (3) to (6), the surface material of the first linear transmission member and the material of the fixing surface of the first sheet may be a first resin material, the surface material of the second linear transmission member and the material of the fixing surface of the second sheet may be a second resin material, and the softening point of the second resin material may be higher than the softening point of the first resin material.

[0024] This makes it easier to fusion-fix the first linear transmission member to the first sheet via the through hole while suppressing softening of the peripheral edge portion of the second sheet around the through hole.

[0025] (8) In the wiring member of (7), the first resin material may be polyvinyl chloride, and the second resin material may be polyolefin.

[0026] This makes it easier to firmly integrate the first linear transmission member, the surface of which is made of polyvinyl chloride, and the second linear transmission member, the surface of which is made of polyolefin.

[0027] (9) In the wiring member according to any one of (1) to (8), the through hole may be wider than the portion of the fixing region that is fixed to the first sheet.

[0028] In this case, since the through-hole is large, it is easy to securely fix the wiring member to the first sheet.

[0029] (10) In the wiring member of any one of (1) to (9), the second sheet may include a nonwoven layer in which a plurality of fibers are entangled, and the through holes may be larger than the gaps between the plurality of fibers.

[0030] This allows the first linear transmission member to be firmly fixed to the sheet by utilizing the through holes that are larger than the gaps between the multiple fibers.

[0031] [Details of the embodiment of the present disclosure] Specific examples of the wiring member of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0032] [Embodiment] <Overall Configuration of Wiring Member> A wiring member according to an embodiment will now be described. Fig. 1 is a perspective view showing a wiring member 10. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1, Fig. 3 is a cross-sectional view taken along line III-III in Fig. 1, and Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 1. Fig. 5 is a plan view showing the wiring member 10.

[0033] The wiring member 10 includes a first wiring body 20 and a second wiring body 30. The number of wiring bodies included in the wiring member is arbitrary. The wiring member may include three or more wiring bodies.

[0034] The first wiring body 20 includes a first sheet 22 and a first linear transmission member 26. The first sheet 22 is a sheet-like member. The first linear transmission member 26 is a linear medium that transmits electricity or light. By fixing the first linear transmission member 26 to the first sheet 22, the first linear transmission member 26 is held along a fixed path on the first sheet 22.

[0035] When the first wiring body 20 includes a plurality of first linear transmission members 26, the plurality of first linear transmission members 26 are maintained in a parallel state on the first sheet 22. Note that the number of first linear transmission members 26 included in the first wiring body 20 is arbitrary.

[0036] The first linear transmission member 26 is a linear member that transmits electricity, light, or the like. It is assumed that the first linear transmission member 26 is a member that connects components in a vehicle. The first linear transmission member 26 includes a transmission line main body 27 and a coating layer 28. The transmission line main body 27 is a transmission path that transmits electricity or light. For example, if the first linear transmission member 26 is an electric wire, the transmission line main body 27 is a conductor core wire. The conductor core wire is composed of one or more element wires. The element wires are formed from copper, copper alloy, aluminum, aluminum alloy, or the like. Furthermore, if the first linear transmission member 26 is an optical fiber, the transmission line main body 27 is composed of a core and cladding. The coating layer 28 is a layer that covers the transmission line main body 27. For example, if the first linear transmission member 26 is an electric wire, the coating layer 28 is an insulating coating. The coating layer 28 is composed of, for example, a resin material. The resin material that constitutes the coating layer 28 is not particularly limited and can be set as appropriate. The first linear transmission member 26 may be, for example, a general electric wire having a core wire and a coating layer surrounding the core wire, or may be a shielded wire, a twisted wire, an enameled wire, a nichrome wire, an optical fiber, or the like.

[0037] The first linear transmission member 26 that transmits electricity may be any of various signal lines and power lines. A part of the first linear transmission member 26 that transmits electricity may be used as an antenna, a coil, or the like that sends or receives a signal or power to or from space.

[0038] The first linear transmission member 26 may also be a single-core wire. A single-core wire is a single linear object. A single-core wire is a linear transmission member with one transmission path. The first linear transmission member 26 may also be a multi-core wire. A multi-core wire is a composite of multiple linear objects. A multi-core wire is a linear transmission member with multiple transmission paths. A multi-core wire may be, for example, a twisted wire, a cable in which multiple linear objects are assembled and covered with a sheath, or the like.

[0039] For example, a connector may be provided at an end of the first linear transmission member 26. The first linear transmission member 26 is connected to a mating connector via the connector.

[0040] The first sheet 22 is not particularly limited in material, structure, etc., as long as it is capable of fixing the first linear transmission member 26. Regarding the material constituting the first sheet 22, here, the first sheet 22 is formed of a resin material. The material constituting the first sheet 22 may be a material other than resin, such as a metal or an inorganic substance. Furthermore, the first sheet 22 may have a multi-layer structure including a resin layer and a non-resin layer, such as a metal layer. In this embodiment, the description will be made on the assumption that the first sheet 22 is a single resin layer.

[0041] The first sheet 22 may be a nonwoven sheet in which multiple fibers are intertwined without being woven or knitted, a foamed sheet, or a mesh-like sheet. The first sheet 22 may be a sheet having a uniform solid cross section (also called a non-foamed sheet or solid sheet). The first sheet 22 may be a knitted or woven fabric.

[0042] The paths of the first linear transmission members 26 are set depending on the positions of the components to which they are connected, etc. By fixing the multiple first linear transmission members 26 to the first sheet 22, the multiple first linear transmission members 26 are maintained in a state along wiring paths that correspond to the positions of the components to which they are connected, etc. The paths of the multiple first linear transmission members 26 may be configured by a combination of straight paths and curved paths.

[0043] Here, the plurality of first linear transmission members 26 extend linearly along the same path. The plurality of first linear transmission members may be fixed to the first sheet in a manner in which some of the first linear transmission members branch off from the other first linear transmission members. The first sheet may also be formed in a branched shape according to the branching paths of the plurality of first linear transmission members.

[0044] The first sheet 22 and the first linear transmission member 26 may be fixed to each other directly at the contact area. Direct fixation at the contact area means that the first sheet 22 and the first linear transmission member 26 are fixed to each other directly without using a separate adhesive or the like.

[0045] When such a state of direct fixation of the contact regions is formed, the resin may be melted by, for example, heat or a solvent. That is, the state of direct fixation of the contact regions may be a state of direct fixation of the contact regions by heat or a state of direct fixation of the contact regions by a solvent. Preferably, the state of direct fixation of the contact regions is a state of direct fixation of the contact regions by heat.

[0046] The means for achieving the state of direct fixation at the contact sites is not particularly limited, and known means such as fusion can be used. For example, when the state of direct fixation at the contact sites is achieved by heat fusion, various fusion means can be used, such as ultrasonic fusion, heat and pressure fusion, hot air fusion, and high-frequency fusion. Furthermore, when the state of direct fixation at the contact sites is achieved by these means, the first sheet 22 and the first linear transmission member 26 are directly fixed at the contact sites by that means. Specifically, for example, when the state of direct fixation at the contact sites is achieved by ultrasonic fusion, the first sheet 22 and the first linear transmission member 26 are directly fixed at the contact sites by ultrasonic fusion. Therefore, the above-mentioned fusion fixation is one form of direct fixation at the contact sites.

[0047] Here, the outermost layer of the first linear transmission member 26 and the first sheet 22 are fused together. The outermost layer of the first linear transmission member 26 is a covering layer 28 located at the outermost periphery. The covering layer 28 is made of a material that can be fused to the fusion target surface of the first sheet 22. The resin material that makes up the covering layer 28 may be the same type as the resin material that makes up the fusion target surface of the first sheet 22. If the first sheet 22 has a multi-layer structure, the fusion target surface of the first sheet 22 is the outward surface of the layer that is exposed on the side to which the first linear transmission member 26 is fused.

[0048] The first linear transmission member 26 and the first sheet 22 may be fixed intermittently or continuously along the extension direction of the first linear transmission member 26. For example, in the extension direction of the first linear transmission member 26, the fixing portion 23a of the first linear transmission member 26 relative to the first sheet 22 may be formed at the same position as the fixing portion 33a of the second linear transmission member 36 relative to the second sheet 32, or may be formed at a different position.

[0049] The second wiring body 30 includes a second sheet 32 ​​and a second linear transmission member 36. The second sheet 32 ​​is a sheet-like member similar to the first sheet 22. The second linear transmission member 36 is a linear medium that transmits electricity or light similar to the first linear transmission member 26. The second linear transmission member 36 includes, for example, a transmission line main body 37 and a covering layer 38.

[0050] Similar to the first wiring body 20, the second linear transmission member 36 is fixed to the second sheet 32. The fixing target may be directly fixed to the contact portion.

[0051] <Configuration for maintaining the first wiring body and the second wiring body in a stacked state> The following configuration is employed to maintain the first wiring body 20 and the second wiring body 30 in a stacked state.

[0052] First, the through-holes 33 are formed in the second sheet 32. The through-holes 33 are holes that penetrate the second sheet 32 ​​in the thickness direction.

[0053] The first linear transmission member 26 has a fixing region 23 and a clamping region 24 .

[0054] The fixing region 23 is a portion of the first linear transmission member 26 that is fixed to the first sheet 22 in the extension direction of the first linear transmission member 26. The portion of the fixing region 23 that is fixed to the first sheet 22 is a fixing portion 23a. In other words, a circumferential portion of the covering layer 28 of the fixing region 23 faces the first sheet 22. In this facing portion, at least one of the covering layer 28 and the first sheet 22 is melted and bonded to each other. The portion of the fixing region 23 where the covering layer 28 and the first sheet 22 are bonded to each other is the fixing portion 23a. The fixing region 23 is formed over a partial range in the extension direction of the first linear transmission member 26.

[0055] The clamping region 24 is set in a partial range of the first linear transmission member 26 excluding the fixed region 23. For example, the clamping region 24 is set in the ranges on both sides of the fixed region 23 in the extension direction of the first linear transmission member 26.

[0056] As described above, the through hole 33 is formed in the second sheet 32. The first sheet 22 is overlaid on the second sheet 32 ​​so as to close the lower opening of the through hole 33. The first linear transmission member 26 is disposed above the second sheet 32 ​​so as to cross the upper opening of the through hole 33. The first sheet 22 is disposed on one side of the second sheet 32 ​​(the lower side in FIGS. 1 to 4 ), and the first linear transmission member 26 is disposed on the other side of the second sheet 32 ​​(the upper side in FIGS. 1 to 4 ).

[0057] The fixing region 23 of the first linear transmission member 26 is fixed to the first sheet 22 via the through hole 33. The fixing portion 23a is disposed within the through hole 33.

[0058] The clamping region 24 is located on the second sheet 32, away from the through-hole 33. The clamping region is located on the opposite side of the second sheet 32 ​​from the first sheet 22 (upper side in FIGS. 1 to 4 ). Therefore, at least a portion of the second sheet 32 ​​is sandwiched between the clamping region 24 and the first sheet 22. If the clamping regions 24 are located on both sides of the fixing region 23, the second sheet 32 ​​can be sandwiched between the clamping region 24 and the first sheet 22 in the regions on both sides of the fixing region 23.

[0059] For example, when the entire wiring member 10 is viewed in a plan view, it may have a first path region R1 in which the first linear transmission member 26 is laid and a second path region R2 in which the second linear transmission member 36 is laid. Furthermore, the first sheet 22 has a region that extends into each of the first path region R1 and the second path region R2, and the second sheet 32 ​​has a region that extends into each of the first path region R1 and the second path region R2. For example, the first sheet 22 and the second sheet 32 ​​may be formed to have the same shape and size.

[0060] Then, the region of the second sheet 32 ​​that extends into the first path region R1 is superimposed on the region of the first sheet 22 that extends into the first path region R1. Furthermore, the region of the second sheet 32 ​​that extends into the second path region R2 is superimposed on the region of the first sheet 22 that extends into the second path region R2.

[0061] Furthermore, a partial through-hole 33 is formed in the second sheet 32 ​​in a region extending into the first path region R1. The first sheet 22 is exposed in the through-hole 33, and the first linear transmission member 26 is disposed so as to cross the through-hole 33. Therefore, the first sheet 22 located below the second sheet 32 ​​and the first linear transmission member 26 located above the second sheet 32 ​​can face each other and come into direct contact with each other via the through-hole 33. Therefore, with the first sheet 22 and the first linear transmission member 26 in direct contact at the through-hole 33, energy for melting and fixing is applied, for example. This causes the first sheet 22 and the first linear transmission member 26 to be fixed in direct contact at their respective portions.

[0062] Further, near the fixed portion 23a, the second sheet 32 ​​is sandwiched between the first sheet 22 and the sandwiching region 24. This keeps the first sheet 22 and the second sheet 32 ​​in a stacked state.

[0063] A plurality of through holes 33 and fixing portions 23a utilizing the through holes 33 are formed in accordance with the fixing positions of the first linear transmission member 26 relative to the first sheet 22. This allows the first linear transmission member 26 to be held along a predetermined path relative to the stack of the first sheet 22 and the second sheet 32.

[0064] The second linear transmission member 36 is fixed in direct contact with a portion of the second sheet 32 ​​on the opposite side of the first sheet 22. Therefore, the second linear transmission member 36 is also held along a predetermined path relative to the stack of the first sheet 22 and the second sheet 32.

[0065] As described above, the second linear transmission member 36 is located on the same side of the second sheet 32 ​​as the first linear transmission member 26. This makes it easy to arrange both the first linear transmission member 26 and the second linear transmission member 36 side by side on one plane of the first sheet 22. This makes it easier to make the wiring member 10 thinner than when the first linear transmission member and the second linear transmission member are arranged at different positions in the thickness direction of the laminate.

[0066] <Regarding Peel Strength and Resin Material> As described above, sandwiching the second sheet 32 ​​between the first sheet 22 and the first linear transmission member 26 maintains the second sheet 32 ​​in a laminated state relative to the first sheet 22. This maintains the first wiring body 20 and the second wiring body 30 in a laminated state. Therefore, it is preferable that the first linear transmission member 26 be fixed as firmly as possible to the first sheet 22. For example, it is preferable that the surface material of the first linear transmission member 26 has a property such that the peel strength due to fusion with the first sheet 22 is greater than the peel strength due to fusion with the second sheet 32.

[0067] The peel strength may be evaluated as follows. For example, the linear transmission member and sheet of a comparison combination are fused under the same conditions. For example, the linear transmission member and sheet of a comparison combination are ultrasonically fused under the same pressure, pressure time, and vibration conditions. Then, the linear transmission member and sheet of a comparison combination are subjected to the same type of peel test (for example, a test conforming to any test specified in JIS K6854) to evaluate the peel strength. For example, a 180° peel test is performed in which the linear transmission member is folded 180° relative to the sheet and pulled, or a T-peel test is performed in which the sheet and the linear transmission member are pulled in opposite perpendicular directions relative to the fused surfaces. By performing the same type of test on the linear transmission member and sheet of a comparison combination, the magnitude of the peel strength is evaluated.

[0068] The second linear transmission member 36 is fixed to the second sheet 32. For this reason, it is preferable that the coating layer 38, which is the surface material of the second linear transmission member 36, has a property such that the peel strength due to fusion to the second sheet 32 ​​is greater than the peel strength due to fusion to the first sheet 22.

[0069] Such a difference in peel strength can be brought about by the combination of the constituent material of the fixed surfaces of the sheets 22, 32 and the surface material of the linear transmission members 26, 36.

[0070] For example, if the surface layer of the coating layer 28, which is the surface material of the first linear transmission member 26, and the material of the fixing surface of the first sheet 22 are the first resin material, it is easy to firmly fusion-fix the first linear transmission member 26 to the first sheet 22.

[0071] In addition, the surface material of the first linear transmission member 26 and the material of the fixed surface of the first sheet 22 being the first resin material means that the main component of the surface material of the first linear transmission member 26 and the main component of the material of the fixed surface of the first sheet 22 are the same as the main component of the first resin material.

[0072] Furthermore, for example, if the material of the surface layer of the coating layer 38, which is the surface material of the second linear transmission member 36, and the material of the fixing surface of the second sheet 32 ​​are the second resin material, it is easy to firmly fusion-fix the second linear transmission member 36 to the second sheet 32.

[0073] Here, the surface material of the second linear transmission member 36 and the material of the fixed surface of the second sheet 32 ​​being the second resin material means that the main component of the surface material of the second linear transmission member 36 and the main component of the material of the fixed surface of the second sheet 32 ​​are the same as the main component of the second resin material.

[0074] The types of the first resin material and the second resin material are not particularly limited, but may be, for example, polyvinyl chloride, polyolefin, PET (polyethylene terephthalate), or fluororesin. The types of the first resin material and the second resin material may be distinguished by their main components. For example, when a resin material is referred to as polyvinyl chloride, it refers to a resin whose main component is polyvinyl chloride, and when a resin material is referred to as polyolefin, it refers to a resin whose main component is polyolefin. The polyolefin may be PE (polyethylene) or PP (polypropylene).

[0075] The second sheet 32 ​​is sandwiched and fixed between the first sheet 22 and the first linear transmission member 26, and the second linear transmission member 36 is fixed to the second sheet 32. Therefore, when the covering layer 28 of the first linear transmission member 26 and the covering layer 38 of the second linear transmission member 36 are made of different resin materials, it is easy to integrate the two into the same wiring member 10.

[0076] Furthermore, when the first linear transmission member 26 is fusion-fixed to the first sheet 22, it is preferable to minimize the influence of heat and the like on the second sheet 32. Therefore, it is preferable to set the softening point of the second resin material higher than the softening point of the first resin material.

[0077] For this purpose, for example, the first resin material may be polyvinyl chloride and the second resin material may be polyolefin.

[0078] <Size of Through Hole> The size of the through hole 33 is arbitrary, but it is preferable that the through hole 33 is larger than the fixing portion 23a.

[0079] In this embodiment, the through-hole 33 is formed in a square shape.

[0080] The length L2 of the through hole 33 in the extension direction of the first linear transmission member 26 is greater than the length L1 of the fixed portion 23a (see FIG. 4). For example, the length L2 may be 10 mm or more. For example, the length L2 may be 100 mm or less, or may be 50 mm or less.

[0081] Furthermore, the width W2 of the through hole 33 in a direction perpendicular to the extension direction of the first linear transmission member 26 is larger than the width W1 of the fixing portion 23a (see FIG. 2 ). In this embodiment, the width W2 of the through hole 33 is larger than the parallel arrangement width of the multiple (here, three) second linear transmission members 36. Therefore, the multiple (here, three) first linear transmission members 26 cross one through hole 33. The respective fixing regions 23 of the multiple (here, three) first linear transmission members 26 are fixed to the first sheet 22 via one through hole 33. Therefore, the multiple (here, three) fixing portions 23a are positioned parallel to one another within one through hole 33.

[0082] The width W2 of the through hole 33 may be equal to or greater than the welding and fixing width. In the case of ultrasonic welding, the welding and fixing width is the width of a horn used for ultrasonic welding. The width of the horn is considered to be the width that leaves a mark when the horn is pressed against the first sheet 22.

[0083] As described above, if the through hole 33 is larger than the fixing portion 23a, for example, when the first linear transmission member 26 and the first sheet 22 are sandwiched between a horn and tip for ultrasonic fusion, the sandwiched portion can be easily positioned within the through hole 33. This allows the first linear transmission member 26 and the first sheet 22 to be fused and fixed more reliably within the through hole 33.

[0084] 6, assuming that the second sheet 132 includes a nonwoven layer in which a plurality of fibers f are entangled, the through holes 33 are larger than the gaps between the plurality of fibers f. This makes it easier for the first sheet 22 and the first linear transmission member 26 to be firmly fixed together over a large area.

[0085] The size of the through hole 33 does not necessarily have to be large enough to allow multiple first linear transmission members 26 to traverse it. As shown in Fig. 7 , the through hole 233 may be large enough to allow one first linear transmission member 26 to traverse it. In this case, a through hole 233 may be formed corresponding to each of the multiple first linear transmission members 26. Then, the multiple first linear transmission members 26 may be fixed to the first sheet 22 via separate through holes 233.

[0086] <Effects, etc.> With the wiring member 10 configured as described above, when the fixing region 23 of the first linear transmission member 26 is fixed to the first sheet 22 via the through hole 33, at least a portion of the second sheet 32 ​​is sandwiched between the clamping region 24 of the first linear transmission member 26 and the first sheet 22. This fixes the second wiring body 30 to the first wiring body 20.

[0087] Furthermore, the surface material of the first linear transmission member 26 has a property such that the peel strength due to fusion to the first sheet 22 is greater than the peel strength due to fusion to the second sheet 32. Therefore, the first linear transmission member 26 is firmly fixed to the first sheet 22. Therefore, the second sheet is firmly sandwiched and fixed to the first wiring body 20.

[0088] Furthermore, the first wiring body 20 includes a first sheet 22 and a first linear transmission member 26, and the second wiring body 30 includes a second sheet 32 ​​and a second linear transmission member 36. Therefore, the first wiring body 20 and the second wiring body 30, each having the linear transmission member 26 (or 36) fixed thereto, can be easily and securely stacked.

[0089] Furthermore, if the second linear transmission member 36 is positioned on the same side as the first linear transmission member 26 with respect to the second sheet 32, it becomes easier to arrange the first linear transmission member 26 and the second linear transmission member 36 together on the same surface, which contributes to making the wiring member 10 thinner.

[0090] Furthermore, if the surface material of the second linear transmission member 36 has a property such that the peel strength due to fusion to the second sheet 32 ​​is greater than the peel strength due to fusion to the first sheet 22, the second linear transmission member 36 will be firmly fixed to the second sheet 32.

[0091] In the wiring member 10, the above property and the property that the surface material of the first linear transmission member 26 has a peel strength due to fusion to the first sheet 22 that is greater than the peel strength due to fusion to the second sheet 32 ​​are combined, so that even if the outermost layer coating materials of the first linear transmission member 26 and the second linear transmission member 36 are different, each linear transmission member 26, 36 can be firmly fixed to the sheets 22, 32 and each wiring body 20, 30 can be maintained in a stacked state.

[0092] For example, the wiring member 10 may include a mixture of first linear transmission members 26 and second linear transmission members 36 having coating layers 28, 38 made of different resin materials. In this case, if a sheet suitable for fixing the first linear transmission member 26 is prepared, it may be difficult to fix the second linear transmission member 36 to the sheet. Therefore, a first sheet 22 suitable for fixing the first linear transmission member 26 and a second sheet 32 ​​suitable for fixing the second linear transmission member 36 are prepared. By fixing the first linear transmission member 26 to the first sheet 22, the first linear transmission member 26 can be held flat on the first sheet 22 along a predetermined path. Furthermore, by fixing the second linear transmission member 36 to the second sheet 32, the second linear transmission member 36 can be held flat on the second sheet 32 ​​along a predetermined path.

[0093] Next, consider maintaining a stacked state of the first wiring body 20 and the second wiring body 30. However, it may be difficult to fix the first sheet 22, which is suitable for fixing the first linear transmission member 26, and the second sheet 32, which is suitable for fixing the second linear transmission member 36, to each other due to the incompatibility of the resin materials.

[0094] Therefore, at least a portion of the second sheet 32 ​​is sandwiched between the sandwiching region 24 of the first linear transmission member 26 and the first sheet 22, and the second wiring body 30 is fixed to the first wiring body 20. This keeps the first wiring body 20 and the second wiring body 30 in a stacked state.

[0095] Therefore, the wiring member 10 can be easily manufactured by laminating the linear transmission members 26, 36, in which the coating layers 28, 38 are made of a mixture of multiple types of resin materials, in a flat form.

[0096] Furthermore, the surface material of the first linear transmission member 26 and the material of the fixing surface of the first sheet 22 are a first resin material, and the surface material of the second linear transmission member 36 and the material of the fixing surface of the second sheet 32 ​​are a second resin material. In this case, if the softening point of the second resin material is higher than the softening point of the first resin material, it is easy to fusion-fix the first linear transmission member 26 to the first sheet 22 via the through hole 33 while suppressing softening of the peripheral portion of the second sheet 32 ​​around the through hole 33.

[0097] Furthermore, if the first resin material is polyvinyl chloride and the second resin material is polyolefin, it becomes easier to firmly integrate the first linear transmission member 26, whose surface material is polyvinyl chloride, and the second linear transmission member 36, whose surface material is polyolefin.

[0098] Furthermore, if the through-hole 33 is wider than the fixing portion 23a, it is easy to sandwich and fix the first sheet 22 and the first linear transmission member 26 with a fusion fixing member within the through-hole 33. This makes it easy to firmly fix the first linear transmission member 26 to the first sheet 22.

[0099] Furthermore, if the through holes 33 are larger than the gaps between the multiple fibers f, the first linear transmission member 26 can be firmly fixed to the first sheet 22 by utilizing the through holes 33 that are larger than the gaps.

[0100] [Modification] In the above embodiment, a flat body including the second sheet 32 ​​may be used instead of the second wiring body 30. In other words, the flat body fixed to the first wiring body 20 in a superposed state may be a flat body that does not include a linear transmission member.

[0101] In the above embodiment, the linear transmission member may be fixed at a different position relative to the first sheet. For example, another linear transmission member may be fixed to the surface of the first sheet opposite to the second sheet.

[0102] Furthermore, the position of the linear transmission member 36 fixed to the second sheet is not limited to the above example. Instead of or in addition to the linear transmission member fixed to the second sheet on the side opposite to the first sheet, the linear transmission member may be fixed to the surface of the second sheet facing the first sheet.

[0103] In addition, in the above embodiment, the first linear transmission member and the second linear transmission member 36 may intersect in a plan view. Furthermore, the size and shape of the through-holes are not limited to the above example. When the sheet is a mesh sheet, the through-holes may be mesh-like. The fixing portion that fixes the linear transmission member to the sheet may expand to fill the through-holes.

[0104] The configurations described in the above embodiment and modifications can be combined as appropriate as long as they are not mutually contradictory.
