[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 first linear transmission member and a second linear transmission member arranged in parallel, and a sheet to which the first linear transmission member and the second linear transmission member are fixed, at least one of the first linear transmission member and the second linear transmission member is provided in plurality, the sheet includes a first portion to which the first linear transmission member is fixed and a second portion to which the second linear transmission member is fixed, the first portion is folded back with respect to the second portion, and an edge of the first portion and an edge of the second portion are fixed on the opposite side to the folded back portion. The sheet is fixed in a folded state between the first portion and the second portion, so that the first linear transmission member fixed to the first portion and the second linear transmission member fixed to the second portion are stacked. This allows linear transmission members fixed to the sheet material to be easily stacked.

[0012] (2) In the wiring member of (1), a third linear transmission member may be further provided parallel to the first linear transmission member and the second linear transmission member, the sheet may further include a third portion provided adjacent to the second portion and opposite to the first portion, and the third linear transmission member may be fixed to the third portion, whereby the third linear transmission member is arranged in a non-stacked state.

[0013] (3) In the wiring member of (2), the third linear transmission member may be branched off from the first linear transmission member and the second linear transmission member on the sheet. Since the third linear transmission member is not stacked on the first linear transmission member and the second linear transmission member, it can be easily branched off from the first linear transmission member and the second linear transmission member.

[0014] (4) In the wiring member of any one of (1) to (3), the first linear transmission member and the second linear transmission member may be fused to the sheet, whereby the first linear transmission member and the second linear transmission member can be fixed directly to the sheet without a separate fixing member.

[0015] (5) In the wiring member of any one of (1) to (4), the first linear transmission member and the second linear transmission member may be surrounded by the first portion and the second portion, whereby the first linear transmission member and the second linear transmission member are protected by the first portion and the second portion.

[0016] (6) In the wiring member according to any one of (1) to (5), the first portion and the second portion may include a radio wave shielding layer, whereby the first portion and the second portion can serve as shielding layers for the first linear transmission member and the second linear transmission member.

[0017] (7) The mounting structure of the wiring member of the present disclosure includes a wiring member including a first linear transmission member and a second linear transmission member arranged in parallel, a sheet to which the first linear transmission member and the second linear transmission member are fixed, and a mounting partner to which the wiring member is attached, and at least one of the first linear transmission member and the second linear transmission member is provided in plurality, the sheet includes a first portion to which the first linear transmission member is fixed and a second portion to which the second linear transmission member is fixed, the mounting partner includes a protrusion, the first portion is folded back with respect to the second portion, and the protrusion is inserted and fixed between an edge of the first portion and an edge of the second portion on the opposite side to the folded back portion. The protrusion fixes the sheet in a folded state between the first portion and the second portion. As a result, the first linear transmission member fixed to the first portion and the second linear transmission member fixed to the second portion are stacked. As a result, the linear transmission members fixed to the sheet material can be easily stacked.

[0018] [Details of the embodiment of the present disclosure] Specific examples of the wiring member and the mounting structure of the wiring member according to 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.

[0019] [Embodiment 1] The wiring member according to embodiment 1 will be described below. Fig. 1 is a schematic plan view showing a wiring member 10 according to embodiment 1. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. Fig. 3 is a schematic plan view showing the wiring member 10 before being folded back.

[0020] The wiring member 10 includes a plurality of linear transmission members 20 and a sheet 40 .

[0021] Each of the multiple linear transmission members 20 is a linear member that transmits electricity or light, etc. For example, the linear transmission member 20 may be a general electric wire having a core wire and a coating around the core wire, or may be a shielded wire, an electric cable, an enamel wire, a nichrome wire, an optical fiber cable, etc. Each linear transmission member 20 has a transmission line main body 21 and a coating layer 22.

[0022] The transmission line body 21 is a part that transmits electricity or light. The transmission line body 21 corresponds to the conductor core of an electric wire, and corresponds to the core and cladding of an optical fiber cable. Each coating layer 22 covers the transmission line body 21. The coating layer 22 is formed by extrusion coating a resin material or the like around the transmission line body 21. 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.

[0023] The linear transmission member 20 that transmits electricity may be any of various signal lines or power lines. A part of the linear transmission member 20 that transmits electricity may be used as an antenna, coil, or the like that sends or receives signals or power to or from space. The linear transmission member 20 may be a single linear object, or may be a composite of multiple linear objects (such as a twisted wire or a cable in which multiple linear objects are assembled and covered with a sheath). When the linear transmission member 20 is a cable, the sheath is also included in the covering layer 22.

[0024] It is assumed that the multiple linear transmission members 20 are members that connect components in a vehicle. The ends of the linear transmission members 20 extend from the seat 40 and are located outside the seat 40. The intermediate portion of the linear transmission member 20, excluding the ends, is disposed on the seat 40. For example, a connector C is provided on the end of the linear transmission member 20. The linear transmission member 20 is connected to the counterpart component by connecting this connector C to a connector provided on the counterpart 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 end of the linear transmission member 20 may be located on the seat 40. The connector housing of the connector C may be fixed to the seat 40.

[0025] The plurality of linear transmission members 20 include a first linear transmission member 20A and a second linear transmission member 20B. At least one of the first linear transmission member 20A and the second linear transmission member 20B is provided in plurality. Here, both the first linear transmission member 20A and the second linear transmission member 20B are provided in plurality. Note that some linear transmission members 20 are omitted in Figs. 1 and 3. The first linear transmission member 20A and the second linear transmission member 20B are parallel to each other in at least a portion of the section on the sheet 40. In the example shown in Fig. 1, the parallel section of the first linear transmission member 20A and the second linear transmission member 20B covers the entire section arranged on the sheet 40. The first linear transmission member 20A and the second linear transmission member 20B are fixed to different areas on the sheet 40.

[0026] The sheet 40 includes a first portion 41 and a second portion 42. The first linear transmission member 20A is fixed to the first portion 41. The second linear transmission member 20B is fixed to the second portion 42. The first portion 41 is folded back onto the second portion 42 in at least a portion of the parallel section of the first linear transmission member 20A and the second linear transmission member 20B. An edge of the first portion 41 and an edge of the second portion 42 are fixed on the side opposite the folded back portion.

[0027] The first linear transmission member 20A and the second linear transmission member 20B are surrounded by the first portion 41 and the second portion 42. In other words, the sheet 40 is folded back so that the surface to which the linear transmission member 20 is fixed faces inward and the surface opposite to the surface to which the linear transmission member 20 is fixed faces outward.

[0028] The first linear transmission member 20A and the second linear transmission member 20B do not have to be surrounded by the first portion 41 and the second portion 42. In other words, the sheet 40 may be folded back so that the surface opposite to the surface to which the linear transmission member 20 is fixed faces inward and the surface to which the linear transmission member 20 is fixed faces outward. In this case, the first portion 41 and the second portion 42 can be in contact with each other over their entire surfaces. The first portion 41 and the second portion 42 may be fixed over their entire surfaces.

[0029] Here, the multiple linear transmission members 20 further include a third linear transmission member 20C. The number of third linear transmission members 20C needs to be at least one, and may be one or multiple. The third linear transmission member 20C is fixed to a different area of ​​the sheet 40 from the first linear transmission member 20A and the second linear transmission member 20B. The sheet 40 further includes a third portion 43. The third portion 43 is provided adjacent to the second portion 42 and opposite to the first portion 41. The third linear transmission member 20C is fixed to the third portion 43.

[0030] The third linear transmission member 20C is also parallel to the first linear transmission member 20A and the second linear transmission member 20B in at least a part of the parallel section. Here, the third linear transmission member 20C branches off from the first linear transmission member 20A and the second linear transmission member 20B on the sheet 40. Therefore, here, the third linear transmission member 20C is parallel to the first linear transmission member 20A and the second linear transmission member 20B in a part of the parallel section, and is not parallel to them in the other part. Here, the path of the linear transmission member 20 includes a branching portion 24. The branching portion 24 is a portion where the third linear transmission member 20C branches off so as to extend in a different direction from the first linear transmission member 20A and the second linear transmission member 20B.

[0031] Here, the shape of the sheet 40 is formed to follow the path of the linear transmission member 20. The sheet 40 has a branched portion in accordance with the branched path of the linear transmission member 20. The sheet 40 may be formed into one large rectangular shape, or the like.

[0032] The dimension from the folded portion between the first portion 41 and the second portion 42 to the edge of the first portion 41 is the width dimension of the first portion 41. The dimension from the folded portion between the first portion 41 and the second portion 42 to the edge of the second portion 42 is the width dimension of the second portion 42. The width dimension of the first portion 41 is approximately the same as the width dimension of the second portion 42. Therefore, when the first portion 41 is in a state in which it is spread in a plane, the second portion 42 is also in a state in which it is spread in a plane. The width dimension of the first portion 41 may be larger or smaller than the width dimension of the second portion 42. In this case, when the one of the first portion 41 and the second portion 42 with the smaller width dimension is in a state in which it is spread in a plane, the middle part of the one with the larger width dimension is bent (for example, curved) so as to move away from the one with the smaller width dimension.

[0033] The first linear transmission members 20A are parallel to each other with a gap between them. The gap between the first linear transmission members 20A is smaller than the diameter of the first linear transmission members 20A. The gap between the first linear transmission members 20A may be the same as or larger than the diameter of the first linear transmission members 20A. The same applies to the gap between the second linear transmission members 20B and between the third linear transmission members 20C.

[0034] In the wiring member 10, a part of the second linear transmission member 20B enters into the gap between the first linear transmission members 20A. The center of the second linear transmission member 20B is located between the centers of the first linear transmission members 20A. A part of the first linear transmission member 20A enters into the gap between the second linear transmission members 20B. The center of the first linear transmission member 20A is located between the centers of the second linear transmission members 20B. This makes it possible to keep the height of the stacked portion low. However, it is not necessary that a part of the second linear transmission member 20B enters into the gap between the first linear transmission members 20A in the wiring member 10. It is also not necessary that a part of the first linear transmission member 20A enters into the gap between the second linear transmission members 20B.

[0035] 3, the first linear transmission member 20A1 and the second linear transmission member 20B1 are located at the boundary between the first linear transmission member 20A and the second linear transmission member 20B. Before the first portion 41 and the second portion 42 are folded back, the distance between the first linear transmission member 20A1 and the second linear transmission member 20B1 is greater than the distance between the first linear transmission members 20A and the distance between the second linear transmission members 20B. The distance between the first linear transmission member 20A1 and the second linear transmission member 20B1 may be equal to or smaller than the distance between the first linear transmission members 20A and the distance between the second linear transmission members 20B.

[0036] 3, the second linear transmission member 20B2 and the third linear transmission member 20C1 are located at the boundary between the second linear transmission member 20B and the third linear transmission member 20C. The distance between the second linear transmission member 20B2 and the third linear transmission member 20C1 is larger than the distance between the second linear transmission members 20B and the distance between the third linear transmission members 20C. The distance between the second linear transmission member 20B2 and the third linear transmission member 20C1 may be equal to or smaller than the distance between the second linear transmission members 20B and the distance between the third linear transmission members 20C.

[0037] In each drawing, the portion of the sheet 40 where the first portion 41 and the first linear transmission member 20A are fixed is shown as a fixed portion FP1. Similarly, the portion of the sheet 40 where the second portion 42 and the second linear transmission member 20B are fixed is shown as a fixed portion FP2. The portion of the sheet 40 where the third portion 43 and the third linear transmission member 20C are fixed is shown as a fixed portion FP3. The portion of the sheet 40 where the first portion 41 and the second portion 42 are fixed is shown as a fixed portion FP4.

[0038] The fixed portions FP1, FP2, and FP3 are provided at intervals along the extension direction of the linear transmission member 20. The fixed portion FP4 is provided continuously along the extension direction of the linear transmission member 20. The fixed portions FP1, FP2, and FP3 may be provided continuously along the extension direction of the linear transmission member 20. The fixed portion FP4 may be provided at intervals along the extension direction of the linear transmission member 20.

[0039] Here, the first linear transmission member 20A and the second linear transmission member 20B are fused to the sheet 40. The third linear transmission member 20C is also fused to the sheet 40. The first portion 41 and the second portion 42 are also fused. Therefore, the fixed portions FP1, FP2, FP3, and FP4 are all fused portions.

[0040] The means for forming such a fused state is not particularly limited, and various fusion means such as ultrasonic fusion, heat and pressure fusion, hot air fusion, high frequency fusion, etc. can be used. When a fused state is formed by these means, the fused part is in a fused and fixed state by that means. Specifically, for example, when the fused part is formed by ultrasonic fusion, the fused part becomes an ultrasonic fused part.

[0041] 2, the sheet 40 includes a fusion layer 47. Here, the sheet 40 has a two-layer structure of the fusion layer 47 and an additional layer 48. The fusion layer 47 contacts the linear transmission member 20. The fusion layer 47 is fused to the outermost covering layer 22 of the linear transmission member 20. The sheet 40 may have a one-layer structure or a three or more layer structure.

[0042] One surface of the fusion layer 47 is the surface that contacts the linear transmission member 20. The fusion layer 47 contains a resin material, preferably a thermoplastic resin material. The resin material of the fusion layer 47 softens and is fused to the fusion partner. The type of such resin material is not particularly limited, and PVC, PE, PP, PET, etc. can be used. The resin material of the fusion layer 47 is preferably the same as the resin material of the coating layer 22.

[0043] The fixed portion FP1 is a portion where the coating layer 22 of the first linear transmission member 20A and the fusion layer 47 are fused to each other. The fixed portion FP2 is a portion where the coating layer 22 of the second linear transmission member 20B and the fusion layer 47 are fused to each other. The fixed portion FP3 is a portion where the coating layer 22 of the third linear transmission member 20C and the fusion layer 47 are fused to each other.

[0044] The structure of the fusion layer 47 is not particularly limited. For example, the fusion layer 47 may be a sheet having a uniform solid cross section (also called a non-foamed sheet or solid sheet). For example, the fusion layer 47 may be a foamed sheet or the like. For example, the fusion layer 47 may be a fibrous sheet such as a knitted fabric, a woven fabric, or a nonwoven fabric.

[0045] The additional layer 48 may be formed of a different material or have a different structure from the fusion layer 47. The additional layer 48 enhances the function of the fusion layer 47 or adds a function not present in the fusion layer 47 to the sheet 40. The material constituting the additional layer 48 may be a metal or the like in addition to the materials described for the fusion layer 47 above. The structure of the additional layer 48 may be any of the structures described for the fusion layer 47 above. One surface of the additional layer 48 is the surface of the sheet 40 facing the opposite side to the linear transmission member 20.

[0046] The fusion layer 47 and the additional layer 48 are fixed while the other surface of the fusion layer 47 and the other surface of the additional layer 48 are in contact with each other. The manner in which the fusion layer 47 and the additional layer 48 are fixed is not particularly limited, but they may be fixed by fusion or adhesion. For example, if at least one of the fusion layer 47 and the additional layer 48 is a sheet having voids on the surface such as a fiber material sheet or a foam sheet, a resin material or adhesive can be inserted into the voids to fix them. This produces a so-called anchor effect, and the fusion layer 47 and the additional layer 48 are firmly fixed.

[0047] Here, the description will be given assuming that the fusion layer 47 is a solid sheet made of resin, and the additional layer 48 is a fibrous material sheet. Here, the description will be given assuming that the fusion layer 47 and the additional layer 48 are fused together. That is, the resin of the fusion layer 47 penetrates between the fibers of the additional layer 48 in a fluid state, and then hardens. This maintains the state in which the resin of the fusion layer 47 penetrates between the fibers of the additional layer 48, and the fusion layer 47 and the additional layer 48 are firmly fixed together.

[0048] The fusion layer 47 and the additional layer 48 are formed to have the same size (same planar shape). One of the fusion layer 47 and the additional layer 48 may be formed to be larger than the other. The fusion layer 47 and the additional layer 48 are fixed over the entire contact area. The fusion layer 47 and the additional layer 48 may be fixed only in a part of the contact area.

[0049] The sheet 40 may be a soft member. For example, the fusion layer 47 is a resin layer having a uniform solid cross section made of soft resin such as soft PVC, and the additional layer 48 is a nonwoven fabric made of PET, so that the sheet 40 is a soft member. For example, the sheet 40 may have flexibility capable of following the bending of the linear transmission member 20. 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 sheet 40) in the portion where the sheet 40 is provided. However, the sheet 40 may be a member that cannot be curved in the thickness direction. The sheet 40 may be a member that can be bent without cracking when bent in the thickness direction. In this case, the folded portion between the first portion 41 and the second portion 42 is bent.

[0050] Sheet 40 may be a member that cannot bend without cracking when bent in the thickness direction. In this case, a hinge portion may be provided between first portion 41 and second portion 42. The hinge portion may be formed by forming a part of sheet 40 to be partially thin.

[0051] The first portion 41 and the second portion 42 are folded back so that the surface to which the linear transmission member 20 is fixed, i.e., the fusion layer 47, faces inward. Therefore, the fusion layers 47 are in contact with each other at the edge of the first portion 41 and the edge of the second portion 42. The fusion layer 47 of the first portion 41 and the fusion layer 47 of the second portion 42 are fused to each other to form the fixed portion FP4.

[0052] However, it is not essential that the fixing parts FP1, FP2, FP3, and FP4 are fused parts. The fixing parts FP1, FP2, FP3, and FP4 may be fixed in any manner. For example, the fixing parts FP1, FP2, FP3, and FP4 may be adhesive parts fixed via an intervening member such as an adhesive or a double-sided adhesive tape. Also, for example, the fixing parts FP1, FP2, FP3, and FP4 may be sewn parts sewn with thread.

[0053] Furthermore, the fixing parts FP1, FP2, FP3, and FP4 do not need to have the same fixing manner, and some of the fixing manners may be different from the other fixing manners. For example, the fixing parts FP1, FP2, and FP3 may be fused parts, and the fixing part FP4 may be an adhesive part.

[0054] In the example shown in Fig. 2, the first portion 41 and the second portion 42 are curved at the folded-back portion. The first portion 41 and the second portion 42 may be bent at the folded-back portion. The first portion 41 and the second portion 42 may be bent so that no crease remains when the folded-back state is restored to a flat state. The first portion 41 and the second portion 42 may be formed so that a crease remains when the folded-back state is restored to a flat state.

[0055] 2, the first portion 41 and the second portion 42 are not fused at the folded-back portion. The first portion 41 and the second portion 42 may be fused at the folded-back portion. In this case, by fusion-bonding the first portion 41 and the second portion 42 on both sides, the laminated portion of the wiring member 10, which is made up of the first linear transmission member 20A and the second linear transmission member 20B, is more likely to be maintained in a flat shape.

[0056] <Effects of the First Embodiment> According to the wiring member 10 configured as above, the sheet 40 is fixed in a folded state between the first portion 41 and the second portion 42, so that the first linear transmission member 20A fixed to the first portion 41 and the second linear transmission member 20B fixed to the second portion 42 are in a stacked state. This makes it possible to easily stack the linear transmission members 20 fixed to the sheet 40.

[0057] Also, the third linear transmission member 20C is fixed to the third portion 43. As a result, the third linear transmission member 20C is arranged in a non-stacked state. In the wiring member 10, a portion where the linear transmission member 20 is stacked and a portion where it is not stacked are provided. As a result, for example, as shown in FIG. 2, the wiring member 10 is easily routed in a space having regions with different intervals between the routing target members 60, 62. Specifically, a first region and a second region are arranged side by side between the routing target members 60, 62. The second region has a smaller interval than the first region. In this case, the stacked portion of the first portion 41 and the second portion 42 of the wiring member 10 is arranged in the first region, and the third portion 43 is arranged in the second region. As a result, the wiring member 10 is easily routed in the space between the routing target members 60, 62 so as to minimize interference with the routing target members 60, 62.

[0058] In addition, the third linear transmission member 20C branches off from the first linear transmission member 20A and the second linear transmission member 20B on the sheet 40. Because the third linear transmission member 20C is not stacked on the first linear transmission member 20A and the second linear transmission member 20B, it can easily branch off from the first linear transmission member 20A and the second linear transmission member 20B.

[0059] In addition, the first linear transmission member 20A and the second linear transmission member 20B are fused to the sheet 40. This allows the first linear transmission member 20A and the second linear transmission member 20B to be fixed directly to the sheet 40 without using another fixing member. Here, the third linear transmission member 20C and the sheet 40 are also fused. This allows the third linear transmission member 20C to be fixed directly to the sheet 40 without using another fixing member. Here, the first portion 41 and the second portion 42 are also fused. This allows the first portion 41 and the second portion 42 to be fixed directly without using another fixing member.

[0060] In addition, the first linear transmission member 20A and the second linear transmission member 20B are surrounded by the first portion 41 and the second portion 42. As a result, the first linear transmission member 20A and the second linear transmission member 20B are protected by the first portion 41 and the second portion 42.

[0061] [Embodiment 2] The mounting structure for a wiring member according to embodiment 2 will be described. Fig. 4 is a cross-sectional view showing the mounting structure for a wiring member according to embodiment 2. Fig. 5 is an explanatory diagram showing a process for manufacturing the mounting structure 100 for a wiring member according to embodiment 2. In the following description, the same components as those described above are given the same reference numerals and the description thereof will be omitted.

[0062] In the mounting structure 100 for a wiring member, the fixing structure between the first portion 41 and the second portion 42 is different from the fixing structure between the first portion 41 and the second portion 42 in the wiring member 10. The mounting structure 100 for a wiring member includes a wiring member 110 and a mounting mating member 162.

[0063] The wiring member 110 has the same configuration as the above-described wiring member 10, except that the first portion 41 and the second portion 42 are not fused together, and that through holes 44, 45 are formed in the first portion 41 and the second portion 42 of the sheet 140. The through holes 44, 45 are formed at positions corresponding to the edge of the first portion 41 and the edge of the second portion 42. Here, a plurality of through holes 44 are formed in the first portion 41. A plurality of through holes 45 are formed in the second portion 42. The multiple through holes 44, 45 are formed at positions that allow corresponding through holes 44, 45 to overlap with each other.

[0064] The mounting partner 162 includes a protrusion 64. The protrusion 64 is inserted into the through holes 44 and 45. The mounting partner 162 is, for example, one of the above-mentioned wiring target members 60 and 62. Here, an example in which the wiring target member 62 is the mounting partner 162 is described. The mounting partner 162 may be any member in the vehicle, but is assumed to be, for example, a panel, a frame, or the like. The protrusion 64 is assumed to be a locking protrusion protruding from the mounting partner 162. The protrusion 64 includes a pillar portion 65 and a locking piece 66. The pillar portion 65 is formed to be as large as the through holes 44 and 45. When the wiring member 110 is attached to the mounting partner 162, the pillar portion 65 is maintained in a state of being inserted into the through holes 44 and 45. The locking piece 66 is formed, for example, in a cone shape. The locking piece 66 is formed to be larger than the pillar portion 65 and the through holes 44 and 45. When the locking pieces 66 are inserted into the through holes 44, 45, at least one of the locking pieces 66 and the peripheral edges of the through holes 44, 45 elastically deform. Then, after the locking pieces 66 are inserted into the through holes 44, 45, at least one of the locking pieces 66 and the peripheral edges of the through holes 44, 45 elastically return to their original shape. This keeps the protrusions 64 locked to the peripheral edges of the through holes 44, 45.

[0065] The first portion 41 is folded back relative to the second portion 42. A protrusion 64 is inserted into through holes 44, 45 formed in an edge portion of the first portion 41 and through holes 44, 45 formed in an edge portion of the second portion 42 on the opposite side to the folded back portion, and fixed.

[0066] Alternatively, the protruding portion 64 may be, for example, a bolt. A bolt may be protruding from the mounting mating portion 162. A nut may be fastened to the tip of the bolt inserted into the through holes 44, 45. A screw hole may be formed in the mounting mating portion 162. A male screw inserted into the through holes 44, 45 may be fastened to the screw hole.

[0067] According to the wiring member mounting structure 100 configured in this manner, the sheet 140 is fixed in a folded state between the first portion 41 and the second portion 42 by the protrusion 64. This results in a stacked state of the first linear transmission member 20A fixed to the first portion 41 and the second linear transmission member 20B fixed to the second portion 42. This allows the linear transmission members 20 fixed to the sheet 140 to be easily stacked.

[0068] [Variations] FIG. 6 is a cross-sectional view showing a modified example of the wiring members 10 and 110. In FIG.

[0069] In the wiring member 210 according to the modified example, the structure of the sheet 240 is different from the structures of the sheets 40, 140 in the wiring members 10, 110. In the sheet 240, a radio wave shielding layer 248 is provided instead of the additional layer 48 of the sheets 40, 140. This allows the first portion 41 and the second portion 42 to function as shield layers for the first linear transmission member 20A and the second linear transmission member 20B. Note that the radio wave shielding layer 248 may be further laminated between the fusion layer 47 and the additional layer 48 of the sheets 40, 140, or on the outer surface of the additional layer 48.

[0070] The radio wave shielding layer 248 is formed of a conductive material. For example, the radio wave shielding layer 248 is a conductive foil such as an aluminum foil or a copper foil. The conductive foil and the fusion layer 47 can be bonded together by adhesion, fusion, or the like. The radio wave shielding layer 248 may be another resin layer in the sheet on which a conductive pattern is printed.

[0071] Here, the first portion 41 and the second portion 42 are folded back so that the surface to which the linear transmission member 20 is fixed faces inward. The first portion 41 and the second portion 42 surround the first linear transmission member 20A and the second linear transmission member 20B. Therefore, the radio wave shielding layer 248 serves as a shielding layer between the first linear transmission member 20A and the second linear transmission member 20B and the outside. The radio wave shielding layer 248 also serves as a shielding layer between the first linear transmission member 20A and the second linear transmission member 20B and the third linear transmission member 20C.

[0072] The first portion 41 and the second portion 42 may be folded inward on the surface opposite to the surface to which the linear transmission member 20 is fixed. In this case, the first portion 41 and the second portion 42 are interposed between the first linear transmission member 20A and the second linear transmission member 20B. In this case, the radio wave shielding layer 248 is a shielding layer between the first linear transmission member 20A and the second linear transmission member 20B.

[0073] In addition, although the wiring members 10, 110, 210 have been described as including the third linear transmission member 20C, this is not a required configuration. The wiring members 10, 110, 210 do not have to include the third linear transmission member 20C. Even if the wiring members 10, 110, 210 include the third linear transmission member 20C, the path of the third linear transmission member 20C is not limited to the above. For example, the third linear transmission member 20C may be parallel to the first linear transmission member 20A and the second linear transmission member 20B over the entire surface of the sheet 40.

[0074] The sheet may also have a fourth portion on the opposite side of the first portion 41 to the second portion 42. The linear transmission member 20 may include a fourth linear transmission member fixed to the fourth portion. The fourth portion may be folded back onto the first portion 41 and laminated to the first portion 41 and the second portion 42. An edge of the fourth portion may be fixed to the folded back portion of the first portion 41 and the second portion 42.

[0075] Furthermore, the path of the linear transmission member 20 is not limited to the one described above. For example, the path of the linear transmission member 20 may include a bent portion. A bent portion is a portion where multiple linear transmission members 20 bend while remaining parallel. The sheet 40 may have a bent portion corresponding to the bent portion of the linear transmission member 20. Also, an intersection portion where multiple linear transmission members 20 intersect may be provided on the sheet 40.

[0076] 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]
