[0009] [Description of the embodiments of the present disclosure] First, the 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 base member; and a plurality of linear transmission members arranged side by side on the base member, the plurality of linear transmission members including at least one sheathed linear transmission member and a plurality of bare electric wires, the sheathed linear transmission members being arranged between the plurality of bare electric wires.

[0012] According to the wiring member of (1), since the wiring member includes bare electric wires, the material cost for the coating layer of the bare electric wires can be reduced compared to when coated electric wires are used instead of bare electric wires. Since the coated linear transmission member is disposed between a plurality of bare electric wires, the bare electric wires are prevented from being adjacent to each other, and unintentional short circuits between the bare electric wires can be prevented.

[0013] (2) In the wiring member of (1), the height of the coated linear transmission member from the arrangement surface of the base member may be higher than the height of the bare electric wires from the arrangement surface, so that the coated linear transmission member between the bare electric wires can function as an insulating wall higher than the bare electric wires.

[0014] (3) In the wiring member of (2), the coated linear transmission member may have a transmission line body and a coating layer that covers the transmission line body, and the size of the transmission line body may be equal to or larger than the size of the bare wire in a direction perpendicular to the arrangement surface, thereby making it possible to increase the difference in height between the coated linear transmission member and the bare wire from the arrangement surface of the base member.

[0015] (4) In the wiring member according to any one of (1) to (3), the at least one coated linear transmission member may have a first outer linear transmission member arranged on one outer side of the plurality of linear transmission members arranged in parallel on the base member, and a second outer linear transmission member arranged on the other outer side, thereby making it possible to prevent bare wires from being exposed to the side of the wiring member.

[0016] (5) In the wiring member according to any one of (1) to (4), the plurality of linear transmission members may have intersections at which they cross each other in a plan view, the intersections including at least one of a group consisting of a first intersection at which the bare electric wires cross each other, a second intersection at which the bare electric wires cross the coated linear transmission member, and a third intersection at which the coated linear transmission members cross each other. This increases the degree of freedom of the paths of the plurality of linear transmission members on the base member compared to a case where no intersections are provided.

[0017] (6) In the wiring member of (5), the intersection may include the first intersection of the group, which increases the degree of freedom of the bare wire's path on the base member compared to a case in which the first intersection is not provided.

[0018] (7) The wiring member of (6) may further include an insulating sheet disposed between the bare electric wires that cross each other at the first intersection, whereby the insulating sheet can prevent a short circuit between the bare electric wires at the first intersection.

[0019] (8) In the wiring member of (7), the insulating sheet may be partially provided in a region of the base member that includes the first intersection portion, thereby making it possible to prevent the insulating sheet from becoming large.

[0020] In the wiring member according to (9) or (7) or (8), the insulating sheet may have higher insulating properties than the base member. This allows the insulating sheet to be thinner than the base member, thereby preventing an increase in the thickness of the wiring member.

[0021] (10) In the wiring member of (5), the intersection portion may include the first intersection portion and the second intersection portion of the group, the first bare electric wire intersects with the second bare electric wire and the first and second sheathed linear transmission members on both sides of the second bare electric wire to provide the first intersection portion and the second intersection portion, the heights of the first and second sheathed linear transmission members from the arrangement surface of the base member are higher than the height of the second bare electric wire, and a hollow space may be provided between the bare electric wires that intersect with each other at the first intersection portion. This makes it possible to suppress short-circuiting between the bare electric wires at the first intersection portion without providing an insulating sheet or the like.

[0022] (11) In the wiring member of (5), the intersection may include only the second intersection, only the third intersection, or only the second intersection and the third intersection in the group. This prevents the bare electric wires from being crossed, making it easier to prevent short circuits between the bare electric wires.

[0023] (12) In the wiring member of (5), the intersection may include the first intersection, the second intersection, and the third intersection of the group, thereby increasing the degree of freedom of the paths of the bare wires and the coated linear transmission member on the base member.

[0024] (13) The wiring member according to any one of (1) to (12) may include a first wiring body and a second wiring body stacked on each other, each of the first wiring body and the second wiring body including the base member and the plurality of linear transmission members, and the base member of the first wiring body may be in contact with at least one of the plurality of linear transmission members of the second wiring body. This allows the base member of the first wiring body to be a cover member for the plurality of linear transmission members of the second wiring body.

[0025] (14) In the wiring member of (13), the bare electric wires of the first wiring body and the bare electric wires of the second wiring body may have an intersection where they cross each other, and the base member of the first wiring body may be located between the bare electric wires of the first wiring body and the bare electric wires of the second wiring body at the intersection. This makes it possible to prevent a short circuit between the bare electric wires at the intersection by the base member.

[0026] (15) In the wiring member of (13) or (14), the bare electric wire of the first wiring body and the coated linear transmission member of the second wiring body may overlap each other and extend in the same direction, and the coated linear transmission member of the first wiring body and the bare electric wire of the second wiring body may overlap each other and extend in the same direction, thereby preventing the thickness of the wiring member from increasing.

[0027] [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 equivalent to the claims.

[0028] [Embodiment 1] Hereinafter, a description will be given of the wiring member 10 according to embodiment 1. Fig. 1 is a plan view showing the wiring member 10 according to embodiment 1. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1.

[0029] The wiring member 10 includes a base member 20 and a plurality of linear transmission members 30. The base member 20 is formed into a flat shape overall. The plurality of linear transmission members 30 are linear members that transmit electricity, light, or the like. The plurality of linear transmission members 30 are arranged side by side on the base member 20. By fixing the plurality of linear transmission members 30 to the base member 20, the wiring member 10 is maintained in a flat shape.

[0030] The base member 20 is formed in a sheet shape. The base member 20 keeps the multiple linear transmission members 30 aligned. Regarding the material constituting the base member 20, here, the base member 20 is formed of a resin material. The material constituting the base member 20 may be a material other than resin, such as a metal or an inorganic material.

[0031] The structure of the base member 20 may be a single-layer structure or a multi-layer structure of two or more layers. The layer structure of the base member 20 is not particularly limited. For example, the base member 20 may have a layer constituted by a sheet having a uniform solid cross section (also called a non-foamed sheet or solid sheet). For example, the base member 20 may have a layer constituted by a foamed sheet or the like. For example, the base member 20 may have a layer constituted by a fibrous sheet such as a knitted fabric, a woven fabric, or a nonwoven fabric.

[0032] The base member 20 may be a soft member. For example, the base member 20 may have flexibility capable of following the bending of the linear transmission member 30. The wiring member 10 may be capable of bending in the thickness direction (bending such that the fold is along the main surface of the base member 20).

[0033] The multiple linear transmission members 30 include at least one coated linear transmission member 31 and multiple bare electric wires 36. The coated linear transmission member 31 transmits electricity, light, etc. The bare electric wires 36 transmit electricity.

[0034] The bare electric wire 36 is an electric wire that is not provided with an insulating coating layer 33 that covers the periphery of the conductor. In the example shown in Fig. 1 and Fig. 2, the bare electric wire 36 is a stranded wire in which multiple elemental wires 37 are twisted together. In the twisted wire, the multiple elemental wires 37 are joined together to form one conductive path. The bare electric wire 36 may be composed of a single elemental wire 37.

[0035] The coated linear transmission member 31 has a transmission line body 32 and a coating layer 33 that covers the periphery of the transmission line body 32. The transmission line body 32 is a portion that transmits electricity or light. For example, in the coated electric wire 31, the conductor core wire corresponds to the transmission line body 32, and in the optical fiber, the core and the clad correspond to the transmission line body 32. Here, the coated linear transmission member 31 is a coated electric wire 31 having a conductor core wire 32 and an insulating coating layer 33 that covers the periphery of the conductor core wire 32. In the example shown in FIG. 2, the coated electric wire 31 is a general coated electric wire that does not have a shield layer or the like around the insulating coating layer 33. The coated electric wire 31 may be a shielded wire that has a shield layer around the insulating coating layer 33. The coated linear transmission member 31 may be an enameled wire, a nichrome wire (heating wire), an optical fiber, or the like.

[0036] The coated linear transmission member 31 is a single linear object with one transmission path. The coated linear transmission member 31 may be a composite of a plurality of linear objects each having a different transmission path (such as a twisted wire or a cable in which a plurality of linear objects are assembled and covered with a sheath).

[0037] The linear transmission member 30 that transmits electricity may be any of various signal lines and various power lines. A part of the linear transmission member 30 that transmits electricity may be used as an antenna, a coil, or the like that transmits a signal or power to or receives it from space.

[0038] A sheathed linear transmission member 31 is arranged between multiple bare electric wires 36. The space between the parallel bare electric wires 36 is defined as an arrangement space. The number of arrangement spaces is the number of parallel bare electric wires 36 minus one. The number of arrangement spaces may be one or more. The sheathed linear transmission member 31 is arranged in the arrangement space so that the bare electric wires 36 are not adjacent to each other. When there are multiple arrangement spaces, a sheathed linear transmission member 31 is arranged in each arrangement space. The number of sheathed linear transmission members 31 is the same as or greater than the number of arrangement spaces.

[0039] Here, only one sheathed linear transmission member 31 is arranged in one arrangement space. The bare electric wires 36 and the sheathed linear transmission member 31 are arranged alternately between the bare electric wire 36 on one outer side along the parallel direction and the bare electric wire 36 on the other outer side along the parallel direction. This makes it possible to increase the ratio of bare electric wires 36 to the multiple linear transmission members 30. Note that multiple sheathed linear transmission members 31 may be arranged in one arrangement space, and the sheathed linear transmission members 31 may be adjacent to each other.

[0040] The sheathed linear transmission member 31 has a first outer linear transmission member 31L arranged on one outer side of the multiple linear transmission members 30 arranged in parallel on the base member 20, and a second outer linear transmission member 31R arranged on the other outer side. Therefore, here, the sheathed linear transmission members 31 are arranged on both sides of all the parallel bare electric wires 36. The number of sheathed linear transmission members 31 is one or more more than the number of bare electric wires 36 and two or more more than the number of arrangement spaces.

[0041] Here, the height of the coated linear transmission member 31 from the arrangement surface 23 of the base member 20 is higher than the height of the bare electric wire 36 from the arrangement surface 23. In the example shown in FIG. 2, the coated linear transmission member 31 and the bare electric wire 36 are so-called round electric wires having a circular cross section. Therefore, the height of the coated linear transmission member 31 and the bare electric wire 36 from the arrangement surface 23 is approximately the same as the thickness (diameter) of the coated linear transmission member 31 and the bare electric wire 36. The coated linear transmission member 31 is thicker than the bare electric wire 36, which causes the height difference. Note that the coated linear transmission member 31 or the bare electric wire 36 may be other than a round electric wire. For example, when the coated linear transmission member 31 is a so-called rectangular electric wire having a rectangular cross section, when the long side portion is arranged on the arrangement surface 23, the height of the coated linear transmission member 31 from the arrangement surface 23 is approximately the same as the length of the rectangular electric wire in the short side direction.

[0042] Here, the dimension of the transmission line main body 32 is equal to or larger than the dimension of the bare electric wire 36 in the direction perpendicular to the arrangement surface 23. In the example shown in Fig. 2, the coated linear transmission member 31 and the bare electric wire 36 are round electric wires, and therefore the thickness of the transmission line main body 32 is equal to or larger than the thickness of the bare electric wire 36, resulting in the dimensional difference in the direction perpendicular to the arrangement surface 23. As a result, the height of the coated linear transmission member 31 from the arrangement surface 23 is higher than the height of the bare electric wire 36 from the arrangement surface 23 by at least the thickness of the coating layer 33.

[0043] The wiring member 10 may include electric wires that are used as signal lines and electric wires that are used as power lines. In the wiring member 10, all bare electric wires 36 may be signal lines. In the wiring member 10, all electric wires that are used as signal lines may be bare electric wires 36. In the wiring member 10, some of the electric wires that are used as signal lines may be bare electric wires 36, and the other parts may be covered electric wires 31. In the wiring member 10, all electric wires that are used as power lines may be covered electric wires 31.

[0044] The wiring member 10 may include a plurality of electric wires having different conductor sizes. In the present disclosure, the smallest conductor size among the plurality of conductor sizes is referred to as a first conductor size, and the next smallest conductor size after the first conductor size is referred to as a second conductor size. The bare electric wires 36 may be composed of only electric wires of the first conductor size, and the electric wires of the second conductor size and larger conductor sizes may be referred to as covered electric wires 31. All electric wires of the first conductor size may be referred to as bare electric wires 36. Some of the electric wires of the first conductor size may be referred to as bare electric wires 36, and the other parts may be referred to as covered electric wires 31.

[0045] The multiple linear transmission members 30 are members that connect components in a vehicle. For example, a connector 40 is provided at the end of the linear transmission member 30. The connector 40 is connected to a mating connector provided on a mating component, thereby connecting the linear transmission member 30 to the mating component. In other words, the wiring member 10 is used as a wiring member 10 that electrically (or optically) connects various components in a vehicle or the like. The connector 40 may be fixed to the base member 20. The end of the linear transmission member 30 may extend outside the base member 20, and the connector 40 may be provided away from the base member 20.

[0046] The connector 40 may include a terminal 41 and a connector housing 46. The terminal 41 has a first connection portion 42 connected to a mating terminal in a mating connector and a second connection portion 43 connected to the linear transmission member 30. The configuration of the first connection portion 42 can be set appropriately, and may be, for example, a male terminal structure or a female terminal structure. The terminal 41 may include a terminal 41A for the insulated electric wire 31 and a terminal 41B for the bare electric wire 36, the shapes of the second connection portions 43 of which are different from each other. The second connection portion 43A in the terminal 41A for the insulated electric wire 31 has a wire barrel 44 crimped to the conductor core wire and an insulation barrel 45 crimped to the insulating coating layer 33. The second connection portion 43B in the terminal 41B for the bare electric wire 36 has the wire barrel 44 but does not have the insulation barrel 45.

[0047] 1, the covered electric wires 31 and the bare electric wires 36 are connected to the same connector 40. The same covered electric wires 31 and bare electric wires 36 may be connected to different connectors 40. In the example shown in FIG. 1, the arrangement of the covered electric wires 31 and the bare electric wires 36 in the connector 40 and the arrangement of the covered electric wires 31 and the bare electric wires 36 in the base member 20 are the same. The arrangement of the covered electric wires 31 and the bare electric wires 36 in the connector 40 and the arrangement of the covered electric wires 31 and the bare electric wires 36 in the base member 20 may be different from each other.

[0048] The paths of the multiple linear transmission members 30 are set according to the positions of the components to which they are connected. By fixing the multiple linear transmission members 30 to the base member 20, the multiple linear transmission members 30 are maintained along wiring paths according to the positions of the components to which they are connected. The multiple linear transmission members 30 may be fixed to the base member 20 in a manner in which branch portions branch off from a trunk portion. It is sufficient that the wiring member 10 has a portion in which the multiple linear transmission members 30 are parallel to each other.

[0049] The linear transmission member 30 only needs to be fixed to the base member 20, and the fixing structure of the linear transmission member 30 to the base member 20 is not particularly limited. For example, the linear transmission member 30 is fixed to the base member 20. Such a fixing manner may be fixing at a contact portion, fixing at a non-contact portion, or a combination of both. Here, fixing at a contact portion means that the linear transmission member 30 and the base member 20 are fixed by being attached to each other at the contact portion. Fixing at a non-contact portion means a fixing manner other than fixing at a contact portion, and for example, a sewing thread 51, a cover, an adhesive tape, or the like holds the linear transmission member 30 toward the base member 20 or sandwiches the linear transmission member 30 and the base member 20 to maintain the state.

[0050] In the example shown in Figures 1 and 2, the fixed portion 50 between the linear transmission member 30 and the base member 20 is fixed in a non-contacting manner. In the example shown in Figures 1 and 2, the linear transmission member 30 and the base member 20 are fixed by a sewing thread 51. That is, the fixed portion 50 is formed by the sewing thread 51. The pitch of the sewing thread 51 can be set as appropriate. In the example shown in Figure 1, the pitch of the sewing thread 51 of the bare electric wire 36 is the same as the pitch of the sewing thread 51 of the covered electric wire 31. The pitch of the sewing thread 51 of the bare electric wire 36 and the pitch of the sewing thread 51 of the covered electric wire 31 may be different from each other.

[0051] <First modified example of fixing manner between linear transmission member 30 and base member 20> 3 is a cross-sectional view showing a first modified example of the fixing mode between the linear transmission member 30 and the base member 20. In the description of this modified example, the same components as those described so far are given the same reference numerals and the description thereof is omitted. The same applies to the following embodiments and modified examples.

[0052] In the example shown in FIG. 3, the fixing portion 50A between the linear transmission member 30 and the base member 20 is in a state of contact-site fixing. The manner of contact-site fixing may be indirect contact-site fixing, direct contact-site fixing, or both may be used in different regions. Here, indirect contact-site fixing means that the linear transmission member 30 and the base member 20 are indirectly attached and fixed to each other via an adhesive, a pressure-sensitive adhesive, a double-sided adhesive tape, or the like provided between them. Direct contact-site fixing means that the linear transmission member 30 and the base member 20 are directly attached and fixed to each other without using a separate adhesive or the like. In direct contact-site fixing, for example, it is considered that the resin contained in at least one of the linear transmission member 30 and the base member 20 is melted to stick and fix them to each other.

[0053] When the state of directly fixing the contact parts is formed, the resin may be melted by, for example, heat or a solvent. That is, the state of directly fixing the contact parts may be a state of directly fixing the contact parts by heat or a state of directly fixing the contact parts by a solvent. Preferably, the state of directly fixing the contact parts by heat is used.

[0054] At this time, the means for forming the state of direct fixation of the contact parts is not particularly limited, and known means such as welding, fusion, and welding can be used. For example, when forming the state of direct fixation of the contact parts by heat through welding, various welding means such as ultrasonic welding, heat and pressure welding, hot air welding, and high frequency welding can be adopted. Furthermore, when the state of direct fixation of the contact parts is formed by these means, the linear transmission member 30 and the base member 20 are in a state of direct fixation of the contact parts by that means. Specifically, for example, when the state of direct fixation of the contact parts is formed by ultrasonic welding, the linear transmission member 30 and the base member 20 are in a state of direct fixation of the contact parts by ultrasonic welding. In the example shown in FIG. 3, the linear transmission member 30 and the base member 20 are in a state of direct fixation of the contact parts.

[0055] When the linear transmission member 30 and the base member 20 are in a state of being directly fixed at the contact portion, the base member 20 may have a two-layer structure including a first layer 21 and a second layer 22. The first layer 21 is a fixing layer. The linear transmission member 30 is directly fixed to the fixing layer at the contact portion. The fixing layer includes a resin material, preferably a thermoplastic resin material. The resin material of the fixing layer softens and is directly fixed to the fixing partner at the contact portion. The type of such resin material is not particularly limited, and polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc. can be used. It is preferable that the covering layer 33 also has the same resin material as the fixing layer. One surface of the first layer 21 is one main surface of the base member 20.

[0056] The second layer 22 is an additional layer. The second layer 22 is formed of a different material or has a different structure from the fixed layer. The second layer 22 enhances the function of the fixed layer or adds a function not present in the fixed layer to the base member 20. The material constituting the second layer 22 may be a metal, an inorganic material, or the like in addition to the materials described for the fixed layer above. One surface of the second layer 22 is the other main surface of the base member 20.

[0057] The first layer 21 and the second layer 22 are fixed together while the other surface of the first layer 21 and the other surface of the second layer 22 are in contact with each other. The manner in which the first layer 21 and the second layer 22 are fixed together is not particularly limited, but it is preferable that they are fixed together by direct or indirect fixing at the contacting portions. For example, if at least one of the first layer 21 and the second layer 22 is a sheet having voids on the surface, such as a fiber material sheet or a foam sheet, a resin material or an adhesive can be inserted into the voids to fix them together. This produces a so-called anchor effect, and the first layer 21 and the second layer 22 are firmly fixed together.

[0058] Here, the first layer 21 is described as a solid sheet made of resin, and the second layer 22 is described as a fibrous material sheet. Here, the first layer 21 and the second layer 22 are described as being directly fixed to each other at their contacting portions. That is, the resin of the first layer 21 penetrates between the fibers of the second layer 22 while in a fluid state, and is then hardened. This maintains the state in which the resin of the first layer 21 penetrates between the fibers of the second layer 22, and the first layer 21 and the second layer 22 are firmly fixed to each other.

[0059] The first layer 21 and the second layer 22 may be formed to have the same size (same planar shape). One of the first layer 21 and the second layer 22 may be formed larger than the other. The first layer 21 and the second layer 22 are fixed to each other over their entire contact areas. The first layer 21 and the second layer 22 may be fixed to each other over only a portion of their contact areas. For example, the first layer 21 may be a solid sheet made of a soft resin such as soft PVC, and the second layer 22 may be a nonwoven fabric made of PET, so that the base member 20 is a soft member.

[0060] In the case of direct fixing at the contact area, it is preferable that the coating layer 33 of the coated linear transmission member 31 and the first layer 21 contain the same resin as a main component. This allows both the coating layer 33 and the first layer 21 of the coated linear transmission member 31 to soften and bond with the other resin. In addition, in the case of direct fixing at the contact area, the resin of the first layer 21 softens and bonds to the twisted wire. In the example shown in FIG. 3, the bare electric wire 36 is not twisted wire but is made of a single wire 37. The twisted wire may be fixed to the base member 20 at the contact area.

[0061] In the case of fixing at the contact portions, each of the multiple linear transmission members 30 may be fixed in a series over the entire length of the base member 20. Each of the multiple linear transmission members 30 may be fixed to the base member 20 at multiple locations spaced apart along the length of the base member 20. The multiple linear transmission members 30 may be fixed at the contact portions of the base member 20 at the same position along the length of the base member 20. The multiple linear transmission members 30 may be fixed at the contact portions of the base member 20 at different positions along the length of the base member 20. In one linear transmission member 30, the intervals between the multiple fixing points may be the same or different.

[0062] <Second modified example of the fixing manner between the linear transmission member 30 and the base member 20> FIG. 4 is a cross-sectional view showing a second modified example of the manner in which the linear transmission member 30 and the base member 20 are fixed to each other.

[0063] In the example shown in FIG. 4, the fixing manner between the bare electric wire 36 and the base member 20 is different from the fixing manner between the coated linear transmission member 31 and the base member 20. The bare electric wire 36 is provided with a fixing portion 50 fixed by non-contacting fixing, and the coated linear transmission member 31 is provided with a fixing portion 50A fixed by contacting fixing. The fixing portion 50 of the bare electric wire 36 is fixed to the base member 20 by a sewing thread 51, as in the example shown in FIG. 2. The fixing portion 50A of the coated linear transmission member 31 is directly fixed to the base member 20 at a contacting portion, as in the example shown in FIG. 3. However, the combination of the fixing portion of the coated linear transmission member 31 and the fixing portion of the bare electric wire 36 can be set as appropriate.

[0064] <Effects of the First Embodiment> According to the wiring member 10 configured as above, since the wiring member 10 includes the bare electric wire 36, the material cost can be reduced by the covering layer 33 of the bare electric wire 36, compared to the case where the covered electric wire 31 is provided instead of the bare electric wire 36. Since the covered linear transmission member 31 is arranged between the bare electric wires 36, the bare electric wires 36 are prevented from being adjacent to each other, and unintended short circuits between the bare electric wires 36 can be prevented. In addition, since there is no covering layer of the bare electric wires 36, the width dimension (the distance between the first outer linear transmission member 31L and the second outer linear transmission member 31R) when the multiple linear transmission members 30 are arranged can be reduced compared to the case where a covered electric wire is used instead of the bare electric wires 36. As a result, the width dimension of the base member 20 can be reduced, and the material cost can be reduced by this amount.

[0065] In addition, the height of the sheathed linear transmission member 31 from the arrangement surface 23 is higher than the height of the bare electric wires 36 from the arrangement surface 23. This allows the sheathed linear transmission member 31 between the bare electric wires 36 to function as an insulating wall higher than the bare electric wires 36. This makes it possible for conductive dust or dirt to straddle the sheathed linear transmission member 31 and the bare electric wires 36 on one side of the sheathed linear transmission member 31, and the dust or dirt is less likely to come into contact with the bare electric wires 36 on the other side of the sheathed linear transmission member 31.

[0066] In addition, in a direction perpendicular to the arrangement surface 23, the dimension of the transmission line body 32 of the coated linear transmission member 31 is equal to or larger than the dimension of the bare electric wire 36. This makes it possible to increase the difference in height between the coated linear transmission member 31 and the bare electric wire 36 from the arrangement surface 23.

[0067] At least one coated linear transmission member 31 has a first outer linear transmission member 31L arranged on one outer side of the multiple linear transmission members 30 arranged in parallel on the base member 20, and a second outer linear transmission member 31R arranged on the other outer side. This makes it possible to prevent the bare wires 36 from being exposed to the side of the wiring member 10.

[0068] [Embodiment 2] A description will be given of a wiring member according to embodiment 2. Fig. 5 is a plan view showing a wiring member 110 according to embodiment 2. Fig. 6 is a cross-sectional view taken along line VI-VI in Fig. 5.

[0069] The wiring member 110 has an intersection where a plurality of linear transmission members 30 cross each other in a plan view. In the present disclosure, an intersection where bare electric wires 36 cross each other is referred to as a first intersection 60. In addition, in the present disclosure, an intersection where bare electric wires 36 cross each other and coated linear transmission member 31 cross each other is referred to as a second intersection 61. The second intersection 61 may include a second intersection 61L where bare electric wires 36 are located closer to the base member 20 (lower side) than coated linear transmission member 31, and a second intersection 61U where coated linear transmission member 31 is located closer to the base member 20 (lower side) than bare electric wires 36. In the second intersection 61U, bare electric wires 36 are located farther from the base member 20 (upper side) than coated electric wires 31. In addition, in the present disclosure, an intersection where coated linear transmission members 31 cross each other is referred to as a third intersection 62. The intersections in the wiring member 110 include at least one of a group consisting of a first intersection 60, a second intersection 61, and a third intersection 62. In the example shown in FIG.

[0070] In the example shown in Fig. 5, the bare electric wire 36A intersects with the bare electric wire 36B and the covered electric wire 31B. Also, the covered electric wire 31A intersects with the bare electric wire 36B and the covered electric wire 31B. The intersection of the bare electric wire 36A and the bare electric wire 36B is a first intersection 60. The intersection of the bare electric wire 36A and the covered electric wire 31B is a second intersection 61U, and the intersection of the covered electric wire 31A and the bare electric wire 36B is a second intersection 61L. The intersection of the covered electric wire 31A and the covered electric wire 31B is a third intersection 62.

[0071] As shown in FIG. 6, the bare electric wire 36A crosses the bare electric wire 36B and the covered electric wire 31B on both sides of the bare electric wire 36B to provide a first intersection 60 and a second intersection 61U. The height of the covered electric wire 31B from the arrangement surface 23 of the base member 20 is higher than the height of the bare electric wire 36B. At the second intersections 61U on both sides of the first intersection 60, the bare electric wire 36A is supported in contact with the covered electric wire 31B. At the first intersection 60, the bare electric wire 36A is supported above the bare electric wire 36B with a gap therebetween. At the first intersection 60, the bare electric wires 36A and B that cross each other are not in contact with each other. In addition, there is a hollow space between the bare electric wires 36A and B. In this way, even if the bare electric wires 36A, B cross each other, as long as they do not come into contact with each other and can be kept spaced apart enough to insulate them from each other, it is not necessary to provide an insulating sheet 70 or the like between the bare electric wires 36A, B.

[0072] In the example shown in Fig. 5, the intersections are provided so that the linear transmission members 30 branch off from each other. Specifically, the bare electric wire 36A and the covered electric wire 31B cross the bare electric wire 36B and the covered electric wire 31B to branch off from the bare electric wire 36B and the covered electric wire 31B. The bare electric wire 36A and the covered electric wire 31A are parallel to the bare electric wire 36B and the covered electric wire 31B on one end side of the intersection. The bare electric wire 36A and the covered electric wire 31A extend in a different direction from the bare electric wire 36B and the covered electric wire 31B on the other end side of the intersection. The intersections may be provided to change the arrangement of the linear transmission members 30 in the parallel direction.

[0073] In this embodiment, the linear transmission member 30 is not folded back together with the base member 20 to form the intersection. At least one of the pair of linear transmission members 30 constituting the intersection changes its path on the base member 20 individually with respect to the base member 20 without being folded back together with the base member 20.

[0074] [First Modification of the Second Embodiment] Fig. 7 is a plan view showing a first modified example of the wiring member 110 according to embodiment 2. Fig. 8 is a cross-sectional view taken along line VIII-VIII in Fig. 7.

[0075] The wiring member 110A shown in FIG. 7 includes an insulating sheet 70 disposed at the first intersection 60 between the bare wires 36 that intersect with each other.

[0076] The insulating sheet 70 is partially provided in a region including the first intersection 60 with respect to the base member 20. In the example shown in FIG. 7, this region includes the second intersection 61 adjacent to the first intersection 60. This region also includes the second intersection 61U where the bare electric wire 36 forming the first intersection 60 intersects with the covered electric wire 31 adjacent to the first intersection 60. This region also includes the second intersection 61L and the third intersection 62 where the covered electric wire 31A parallel to the bare electric wire 36 forming the first intersection 60 intersects with the bare electric wire 36B and the covered electric wire 31B. The region where the insulating sheet 70 is provided may include only the first intersection 60 without including the second intersection 61 and the third intersection 62. The region where the insulating sheet 70 is provided may include only the first intersection 60 and the second intersection 61L without including the second intersection 61U and the third intersection 62. The region in which the insulating sheet 70 is provided may not include the second intersection portion 61L and the third intersection portion 62, but may include only the first intersection portion 60 and the second intersection portion 61U.

[0077] The insulating sheet 70 may have higher insulating properties than the base member 20. For example, the nonwoven fabric of the base member 20 is made of PET, and the insulating sheet 70 is made of a nonwoven fabric containing aramid fiber or glass fiber, so that the insulating sheet 70 can have higher insulating properties than the base member 20.

[0078] [Second Modification of the Second Embodiment] Fig. 9 is a plan view showing a second modified example of the wiring member 110 according to the embodiment 2. Fig. 10 is a cross-sectional view taken along the line XX in Fig. 9.

[0079] The intersection portion may be configured not to include the first intersection portion 60. The intersection portion of the wiring member 110B according to the second modified example does not include the first intersection portion 60, and includes only the second intersection portion 61 and the third intersection portion 62. The intersection portion may not include the first intersection portion 60 and the third intersection portion 62, and includes only the second intersection portion 61. The intersection portion may not include the first intersection portion 60 and the second intersection portion 61, and includes only the third intersection portion 62.

[0080] <Effects of the Second Embodiment and its Modifications> The wiring members 110, 110A, and 110B according to the second embodiment and its modifications can also provide the same effects as the wiring member 10 according to the first embodiment.

[0081] Furthermore, the wiring members 110, 110A, and 110B have intersections where multiple linear transmission members 30 intersect with each other in a planar view, thereby increasing the freedom of the paths of the multiple linear transmission members 30 on the base member 20 compared to when no intersections are provided.

[0082] Moreover, in the wiring members 110 and 110A, the intersection includes the first intersection 60. This increases the degree of freedom of the path of the bare wires 36 on the base member 20 compared to a case in which the first intersection 60 is not provided.

[0083] Moreover, according to the wiring members 110 and 110A, the intersection portion includes a first intersection portion 60, a second intersection portion 61, and a third intersection portion 62. This increases the degree of freedom of the paths of the bare wires 36 and the coated linear transmission members 31 on the base member 20.

[0084] Furthermore, in the wiring member 110, the height of the covered electric wires 31B on both sides of the bare electric wire 36B from the arrangement surface 23 is greater than the height of the bare electric wire 36B from the arrangement surface 23, and a hollow space is formed between the mutually intersecting bare electric wires 36A, 36B at the first intersection 60. This makes it possible to prevent a short circuit between the bare electric wires 36A, 36B at the first intersection 60 without providing an insulating sheet 70 or the like.

[0085] Furthermore, in the wiring member 110A, the insulating sheet 70 can prevent the bare wires 36 from shorting out at the first intersection 60.

[0086] Furthermore, in the wiring member 110A, the insulating sheet 70 is provided partially in a region including the first intersection portion 60 with respect to the base member 20, so that the insulating sheet 70 can be prevented from becoming large.

[0087] Furthermore, in the wiring member 110A, since the insulating sheet 70 has higher insulation properties than the base member 20, the insulating sheet 70 can be made thinner than the base member 20, and an increase in the thickness of the wiring member 10 can be suppressed.

[0088] Furthermore, the wiring member 110B prevents the bare electric wires 36 from intersecting with each other, making it easier to prevent the bare electric wires 36 from shorting each other.

[0089] [Embodiment 3] A description will be given of a wiring member according to embodiment 3. Fig. 11 is a plan view showing a wiring member 210 according to embodiment 3. Fig. 12 is a cross-sectional view taken along line XII-XII in Fig. 11.

[0090] The wiring member 210 includes a first wiring body 11 and a second wiring body 12 stacked on each other. Each of the first wiring body 11 and the second wiring body 12 includes a base member 20 and a plurality of linear transmission members 30. The base member 20 of the first wiring body 11 is in contact with at least one of the plurality of linear transmission members 30 of the second wiring body 12. In the stacked portion of the first wiring body 11 and the second wiring body 12, in the example shown in FIG. 12, the coated electric wires 31 overlap each other and the bare electric wires 36 overlap each other. In the example shown in FIG. 12, the base member 20 of the first wiring body 11 is in contact with the coated electric wire 31 of the second wiring body 12. The base member 20 of the first wiring body 11 may have higher insulation than the base member 20 of the second wiring body 12. The nonwoven fabric of the base member 20 of the first wiring body 11 may be configured similarly to the nonwoven fabric of the insulating sheet 70.

[0091] The first wiring body 11 and the second wiring body 12 are laminated in portions extending along the same path. In the example shown in FIG. 11, the first wiring body 11 and the second wiring body 12 are branched midway, and the laminated state is eliminated. The wiring member 210 is provided with a laminated extending portion in which the first wiring body 11 and the second wiring body 12 are laminated and extend along the same path, and an individual extending portion in which the first wiring body 11 and the second wiring body 12 extend individually without being laminated. The first wiring body 11 and the second wiring body 12 may remain laminated from one end to the other end without branching midway. The wiring member 210 may not be provided with an individual extending portion.

[0092] The wiring member 210 has an intersection portion where the bare electric wires 36 of the first wiring body 11 and the bare electric wires 36 of the second wiring body 12 intersect with each other. As shown in Fig. 11, here, when the first wiring body 11 bends and branches off from a common path with the second wiring body 12, the bare electric wires 36 of the first wiring body 11 and the bare electric wires 36 of the second wiring body 12 intersect with each other to provide a first intersection portion 60. At the first intersection portion 60, the base member 20 of the first wiring body 11 is located between the bare electric wires 36 of the first wiring body 11 and the bare electric wires 36 of the second wiring body 12.

[0093] [First Modification of the Third Embodiment] FIG. 13 is a cross-sectional view showing a first modified example of the wiring member 210 according to the third embodiment.

[0094] In the wiring member 210A according to the first modification, the bare electric wire 36 of the first wiring body 11 and the covered linear transmission member 31 of the second wiring body 12 overlap each other and extend in the same direction, and the covered linear transmission member 31 of the first wiring body 11 and the bare electric wire 36 of the second wiring body 12 overlap each other and extend in the same direction. In the example shown in Fig. 13, the first wiring body 11 is deformed so that the covered electric wire 31 of the first wiring body 11 enters the space above the bare electric wire 36 of the second wiring body 12 and between the covered electric wires 31.

[0095] <Effects of the Third Embodiment and its Modifications> The wiring members 210 and 210A according to the third embodiment and its modified example can also provide the same effect as the wiring member 10 according to the first embodiment. In particular, since there is no covering layer on the bare electric wires 36, the width dimension (the distance between the first outer linear transmission member 31L and the second outer linear transmission member 31R) when multiple linear transmission members 30 are arranged can be made smaller than when a covered electric wire is used instead of the bare electric wires 36. This increases the number of multiple linear transmission members that can be arranged side by side on one base member having a predetermined width. This can reduce the number of layers in the laminated portion, compared to when a covered electric wire is used instead of the bare electric wires 36, and can reduce the material cost accordingly.

[0096] Furthermore, according to the wiring members 210 and 210A, the base member 20 of the first wiring body 11 can be used as a cover member for the multiple linear transmission members 30 of the second wiring body 12.

[0097] Furthermore, according to the wiring member 210, at the intersection where the bare electric wires 36 of the first wiring body 11 and the bare electric wires 36 of the second wiring body 12 intersect, the base member 20 of the first wiring body 11 is located between the bare electric wires 36 of the first wiring body 11 and the bare electric wires 36 of the second wiring body 12. This makes it possible for the base member 20 to suppress short circuits between the bare electric wires 36 at the intersection where the bare electric wires 36 intersect.

[0098] Furthermore, in the wiring member 210A, the coated linear transmission member 31 and the bare wires 36 overlap between different wiring bodies, so that the thickness of the wiring member 10 can be prevented from increasing.

[0099] [Note] In the above wiring members 10, 110, 110A, and 110B, a cover member that covers the linear transmission member 30 from the opposite side to the base member 20 is not provided. In the wiring members 10, 110, 110A, and 110B, a cover member that covers the linear transmission member 30 from the opposite side to the base member 20 may be provided. The same applies to the first wiring body 11 in the laminated portion of the above wiring member 210. Such a cover member may be fixed to the base member 20 without being fixed to the linear transmission member 30. The cover member may be in contact with the linear transmission member 30, or may not be fixed thereto.

[0100] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually inconsistent. [Explanation of symbols]
