[0009] [Description of the 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 first wiring body including a first sheet and a first linear transmission member directly fixed to the first sheet at a contact portion; a second wiring body including a second sheet and a second linear transmission member directly fixed to the second sheet at a contact portion; and a fixing portion to which the first sheet and the second sheet are fixed, wherein the first linear transmission member has a first transmission line body and a first coating layer covering the first transmission line body, and the second linear transmission member has a second transmission line body and a second coating layer covering the second transmission line body, wherein the first sheet and the first coating layer are each formed from a first resin material, and the second sheet and the second coating layer are each formed from a second resin material different from the first resin material, and wherein the second resin material fills a hole formed in the first sheet in a portion of the fixing portion where the first sheet and the second sheet overlap.

[0012] According to the wiring member (1), the first covering layer and the first sheet of the first linear transmission member are made of the same first resin material, so they can be firmly and directly fixed at their contact points. The second covering layer and the second sheet of the second linear transmission member are made of the same second resin material, so they can be firmly and directly fixed at their contact points. Because the holes in the first sheet are filled with the second resin material to form the fixing portion, the first sheet and the second sheet can be firmly and directly fixed at their contact points even if they are made of different resin materials. As a result, multiple types of linear transmission members with different covering materials can be well fixed by directly fixing their contact points. Furthermore, because the sheets can be fixed to each other by directly fixing their contact points, it is possible to reduce the number of fixing parts required by fixing methods other than directly fixing their contact points.

[0013] (2) The wiring member of (1) may further include an additional sheet portion provided on the side of the first sheet opposite the second sheet so as to cover the hole, the additional sheet portion being made of the second resin material, and the additional sheet portion and the second sheet being directly fixed to each other at a contact area via the hole, thereby increasing the strength of the fixing portion.

[0014] (3) In the wiring member of (2), the size of the hole may be larger than the diameter of the first linear transmission member, thereby increasing the direct fixing area at the contact point between the second sheet and the additional sheet portion and increasing the strength of the fixing part.

[0015] (4) In the wiring member of (1), only the first sheet and the second sheet may overlap in the fixing portion, thereby reducing the number of components constituting the fixing portion.

[0016] (5) In the wiring member of (4), the first sheet may be a nonwoven fabric, and the holes may be gaps between fibers that make up the nonwoven fabric. This allows the gaps between the fibers that make up the nonwoven fabric to be used as holes, eliminating the need to separately drill holes in the first sheet for the fixing parts.

[0017] (6) In the wiring member of (4), the first sheet may be a mesh sheet, and the holes may be holes in the mesh sheet. This allows the holes in the mesh sheet to be used as holes for the fixing parts, eliminating the need to drill additional holes for the fixing parts in the first sheet.

[0018] (7) In the wiring member of any one of (1) to (6), the softening point of the first resin material may be higher than the softening point of the second resin material, thereby making it easier for the second resin material to penetrate into the holes in the first sheet while suppressing softening of the peripheral portions of the holes in the first sheet.

[0019] (8) In the wiring member of (7), the first resin material may be polyolefin, and the second resin material may be polyvinyl chloride, which makes it easier to firmly integrate the linear transmission member having a polyolefin coating and the linear transmission member having a polyvinyl chloride coating.

[0020] [Details of the embodiments of the present disclosure] Specific examples of wiring members 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.

[0021] [Embodiment 1] The wiring member according to embodiment 1 will be described below. Fig. 1 is a 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 diagram showing an example of a method for manufacturing the wiring member 10.

[0022] The wiring member 10 includes a first wiring body 20, a second wiring body 30, and a fixing portion 40. The first wiring body 20 and the second wiring body 30 are each flat wiring bodies. Here, flat means that the dimension in the thickness direction is smaller than the dimension in the width direction and the dimension in the extension direction. The first wiring body 20 and the second wiring body 30 overlap each other in the thickness direction. The fixing portion 40 fixes the first wiring body 20 and the second wiring body 30 together, maintaining the first wiring body 20 and the second wiring body 30 in an overlapped state. The wiring member 10 formed by overlapping the first wiring body 20 and the second wiring body 30 may also be flat.

[0023] The first wiring body 20 includes a first sheet 21 and a first linear transmission member 24. The first linear transmission member 24 is fixed to the first sheet 21. The first linear transmission member 24 has a first transmission line body 25 and a first covering layer 26. The first covering layer 26 covers the first transmission line body 25.

[0024] The second wiring body 30 includes a second sheet 31 and a second linear transmission member 34. The second linear transmission member 34 is fixed to the second sheet 31. The second linear transmission member 34 has a second transmission line body 35 and a second covering layer 36. The second covering layer 36 covers the second transmission line body 35.

[0025] The first linear transmission member 24 and the second linear transmission member 34 are linear members that transmit electricity, light, etc., i.e., linear transmission members. For example, the linear transmission member may be a general electric wire having a core wire and an insulating coating surrounding the core wire. For example, the linear transmission member may be a shielded wire in which a coated electric wire is covered with a shielding layer and an outer jacket. The shielding layer may be a conductive foil or braid, etc. The linear transmission member may be a twisted wire in which multiple electric wires are twisted together. The linear transmission member may also be an optical fiber, etc.

[0026] The linear transmission member that transmits electricity may be any of various signal lines or power lines. The linear transmission member that transmits electricity may be used as an antenna, coil, etc. that sends or receives signals or power to or from space. Furthermore, the linear transmission member may be a single linear object, or a composite of multiple linear objects (such as a twisted wire or a cable made up of multiple linear objects gathered together and covered with a sheath).

[0027] For example, the first linear transmission member 24 is a first electric wire including a first core wire as a first transmission line main body 25 and a first insulating coating layer as a first coating layer 26 that covers the periphery of the first core wire. The first coating layer 26 is a layer that is exposed on the surface of the first linear transmission member 24. Therefore, the material of the surface of the first linear transmission member 24 is the material that forms the first coating layer 26. Here, the first linear transmission member 24 does not have another layer between the first transmission line main body 25 and the first coating layer 26. The first linear transmission member 24 may have another layer (for example, an intermediate insulating coating layer that covers the core wire and a shielding layer that covers the intermediate insulating coating layer) between the first transmission line main body 25 and the first coating layer 26.

[0028] Further, for example, the second linear transmission member 34 is a second electric wire including a second core wire as a second transmission line main body 35 and a second insulating coating layer as a second coating layer 36 that covers the periphery of the second core wire. The second coating layer 36 is a layer that is exposed on the surface of the second linear transmission member 34. Therefore, the material of the surface of the second linear transmission member 34 is the material that forms the second coating layer 36. Here, the second linear transmission member 34 does not have another layer between the second transmission line main body 35 and the second coating layer 36. The second linear transmission member 34 may have another layer (for example, an intermediate insulating coating layer that covers the core wire and a shielding layer that covers the intermediate insulating coating layer) between the second transmission line main body 35 and the second coating layer 36.

[0029] For example, connectors C are provided at the ends of the first linear transmission member 24 and the second linear transmission member 34. The wiring member 10 is connected to equipment or the like via the connectors C. The first linear transmission member 24 and the second linear transmission member 34 may be connected to the same connector C. The first linear transmission member 24 may be connected to a first connector, and the second linear transmission member 34 may be connected to a second connector different from the first connector. The first connector and the second connector may be connected to different mating connectors. The first connector and the second connector may be stacked to form a single connector, and the single connector may be connected to a single mating connector.

[0030] The first sheet 21 and the second sheet 31 are made of sheet members. The sheet members include a fusion layer. The fusion layer includes a resin material, preferably a thermoplastic resin material. The resin material of the fusion layer softens and is fused to the fusion partner.

[0031] The structure of the bonding layer is not particularly limited. For example, the bonding layer may be a sheet having a uniform solid cross section (also called a non-foamed sheet or a solid sheet). For example, the bonding layer may be a foamed sheet. For example, the bonding layer may be a fibrous sheet such as a knitted fabric, a woven fabric, or a non-woven fabric.

[0032] The sheet member may have a single layer structure consisting of a fusion layer. The sheet member may have a multi-layer structure. When the sheet member has a multi-layer structure, the fusion layer may appear on at least one main surface of the sheet member. When the sheet member has a multi-layer structure, the sheet member may have an additional layer laminated on the fusion layer.

[0033] The additional layer may be formed of a different material or have a different structure from the fusion layer. The additional layer enhances the functionality of the fusion layer or adds functionality not present in the fusion layer to the sheet member. The material constituting the additional layer may be a metal or the like in addition to the materials described for the fusion layer above. The structure of the additional layer may be any of the structures described for the fusion layer above. The fusion layer and the additional layer may be formed to the same size (same planar shape). One of the fusion layer and the additional layer may be formed larger than the other. The fusion layer and the additional layer may be fixed over the entire contact area. The fusion layer and the additional layer may be fixed over only a portion of the contact area.

[0034] The sheet member may be a flexible member. For example, the sheet member may have flexibility that allows it to follow the bending of the linear transmission member to which it is fixed. Each wiring body may be bendable in the thickness direction (bending such that the folds are along the main surface of the sheet member).

[0035] The planar shape of the sheet member is formed to a shape corresponding to the path of the linear transmission member. In the example shown in FIG. 1, the sheet member includes multiple (two in the example shown in FIG. 1) straight path sections. The portion where the multiple straight path sections intersect with each other is defined as a curved path section. The curved path section is a portion that bends according to the curved path of the linear transmission member. The sheet member may consist of one straight path section. In the example shown in FIG. 1, the sheet member does not have a branch section. The sheet member may have a branch section. The linear transmission member may branch at the branch section of the sheet member.

[0036] The fixing portion 40 is a portion where the first sheet 21 and the second sheet 31 are fixed. The fixing portion 40 is formed by direct fixation at the contact area. In addition to the fixing portion 40, FIG. 1 shows a wire fixing portion 50 formed by direct fixation at the contact area between the first linear transmission member 24 and the first sheet 21. A wire fixing portion formed by direct fixation at the contact area between the second linear transmission member 34 and the second sheet 31 may also be provided in the same position as the wire fixing portion 50. The fixation between the first linear transmission member 24 and the first sheet 21, and the fixation between the second linear transmission member 34 and the second sheet 31 are also direct fixation at the contact area.

[0037] Here, direct fixation of contacting parts means that the contacting parts of the two components to be fixed are directly attached and fixed to each other without the use of a separate adhesive, etc. In direct fixation of contacting parts, for example, it is thought that the two components to be fixed are attached and fixed by melting a resin contained in at least one of the components.

[0038] 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.

[0039] In this case, the means for forming the state of direct fixation at the contact sites 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 at the contact sites by heat welding, various welding means can be used, such as ultrasonic welding, heat and pressure welding, hot air welding, and high-frequency welding. Furthermore, when the state of direct fixation at the contact sites is formed by these means, the two members to be fixed are in a state of direct fixation at the contact sites by that means. Specifically, for example, when the state of direct fixation at the contact sites is formed by ultrasonic welding, the two members to be fixed are in a state of direct fixation at the contact sites by ultrasonic welding.

[0040] The fusion layer of the first sheet 21 and the first covering layer 26 are each formed from a first resin material. The fusion layer of the second sheet 31 and the second covering layer 36 are each formed from a second resin material. Here, the first resin material and the second resin material are materials that are the main components of each of the sheets 21, 31 and each of the covering layers 26, 36. The first resin material and the second resin material are different resin materials. Different resin materials refer to resins of different types. Therefore, even if the degree of polymerization, amount of additives, etc. are different, they can be considered to be the same resin material as long as the type of resin that is the main component is the same.

[0041] For example, PVC (polyvinyl chloride) and polyolefin may be used as the first resin material and the second resin material. PP (polypropylene) and PE (polyethylene) are types of polyolefin. The first resin material may be one of PVC and polyolefin, and the second resin material may be the other of PVC and polyolefin. In this example, the first resin material is polyolefin, and the second resin material is PVC.

[0042] The fixing strength of the contact portions of the first resin materials when directly fixed to each other is higher than the fixing strength of the contact portions of the first resin material and the second resin material. The fixing strength of the contact portions of the second resin materials when directly fixed to each other is higher than the fixing strength of the contact portions of the first resin material and the second resin material. For example, when the first linear transmission member 24 is directly fixed to each of the first sheet 21 and the second sheet 31 under the same conditions, the fixing strength between the first linear transmission member 24 and the first sheet 21 is greater than the fixing strength between the first linear transmission member 24 and the second sheet 31. Similarly, when the second linear transmission member 34 is welded to each of the first sheet 21 and the second sheet 31 under the same conditions, the fixing strength between the second linear transmission member 34 and the second sheet 31 is greater than the fixing strength between the second linear transmission member 34 and the first sheet 21.

[0043] Here, sufficient fixing strength is likely to be obtained in the wire fixing portion 50 in which the same resin materials are directly fixed at the contact area. In contrast, in the fixing portion 40 in which the first resin material and the second resin material are directly fixed at the contact area, sufficient fixing strength may not be obtained if the flat portions of the solid sheets are directly fixed at the contact area. Here, in the portion of the fixing portion 40 where the first sheet 21 and the second sheet 31 overlap, the second resin material of the second sheet 31 fills the holes 22 formed in the first sheet 21. As a result, sufficient fixing strength is likely to be obtained even in the fixing portion 40 in which the first resin material and the second resin material are directly fixed at the contact area.

[0044] For example, the fixing part 40 includes a hook portion 44 provided around the hole 22. The hook portion 44 is formed by filling the hole 22 formed in the first sheet 21 with the second resin material. The hook portion 44 is a portion where the second resin material is hooked onto the first resin material by being located on the opposite side of the first resin material from the second sheet 31. The provision of this hook portion 44 strengthens the fixing strength of the fixing part 40, which directly fixes the first resin material and the second resin material at the contact area.

[0045] The fixing portion 40 may be made of only the second resin material derived from the second sheet 31. In this case, the hooking portion 44 is made of only the second resin material derived from the second sheet 31 that protrudes from the hole 22. The fixing portion 40 may be made of the second resin material derived from the second sheet 31 and a second resin material derived from a member other than the second sheet 31. In this case, the hooking portion 44 may be made of the second resin material derived from the second sheet 31 and a second resin material derived from a member other than the second sheet 31.

[0046] Here, the wiring member 10 includes an additional sheet portion 42. The additional sheet portion 42 is provided on the side of the first sheet 21 opposite the second sheet 31 so as to cover the hole 22. The additional sheet portion 42 is formed from a second resin material. The additional sheet portion 42 and the second sheet 31 are directly fixed to each other at the contact area via the hole 22. By providing the additional sheet portion 42, the catch portion 44 can be strengthened.

[0047] The additional sheet portion 42 may be formed larger than the hole 22. The additional sheet portion 42 may have a central portion 43 (a portion that fits within the hole 22) that overlaps with the hole 22, and an outer peripheral portion 44 that extends outward from the central portion 43 and overlaps with the peripheral portion of the hole 22 in the first sheet 21. The central portion 43 is directly fixed to the second sheet 31 at the contact portion via the hole 22. The outer peripheral portion 44 may be directly fixed to the first sheet 21 at the contact portion.

[0048] The additional sheet portion 42 may be made of the same sheet material as the second sheet 31. The additional sheet portion 42 may have the same hardness as the second sheet 31. The additional sheet portion 42 may be formed to be harder than the second sheet 31. In this case, even if the outer peripheral portion 44 of the additional sheet portion 42 is not directly fixed to the first sheet 21 at the contact area, the additional sheet portion 42 is likely to get caught on the peripheral edge of the hole 22.

[0049] Here, the additional sheet portion 42 and the second sheet 31 are separated from each other except at the fixed portion 40. The additional sheet portion 42 and the second sheet 31 may also be connected at a location other than the fixed portion 40. For example, the additional sheet portion 42 may be a portion formed by folding back a portion of the sheet member constituting the second sheet 31 adjacent to the hole 22. The portion of the sheet member constituting the second sheet 31 adjacent to the hole 22 may be a portion located outside the hole 22 along the width direction of the sheet member, or may be a portion located adjacent to the hole 22 along the extension direction of the linear transmission member.

[0050] Here, the holes 22 are through-holes additionally formed in the first sheet 21. For example, the first sheet 21 may be a solid sheet, and holes 22 may not be formed in the first sheet 21 except at specific positions such as the fixing portion 40. Alternatively, for example, the first sheet 21 may be a sheet member having holes derived from the sheet member, and the holes 22 in the fixing portion 40 may be holes provided separately from the holes derived from the sheet member. The holes derived from the sheet member may be, for example, gaps between fibers of a nonwoven fabric. The shape of the holes 22 is not particularly limited and can be set as appropriate. For example, the shape of the holes 22 may be square or circular.

[0051] 3, with the second sheet 31 and the additional sheet portion 42 positioned on both sides of the hole 22, the first sheet 21, the second sheet 31, and the additional sheet portion 42 are fused together by a fusion machine 80 or the like to form the fixing portion 40. The fusion machine 80 may be, for example, an ultrasonic fusion machine having a horn and an anvil.

[0052] Here, one hole 22 is formed in one fixing portion 40. A plurality of holes 22 may be formed in one fixing portion 40. The additional sheet portion 42 may be provided so as to cover the portions of the first sheet 21 between the plurality of holes 22. This makes it easier for the additional sheet portion 42 to be caught in the portions of the first sheet 21 between the plurality of holes 22.

[0053] The size of the hole 22 is not particularly limited and can be set appropriately. For example, the size of the hole 22 may be larger or smaller than the diameter of the first linear transmission member 24. When linear transmission members of multiple sizes are provided as the first linear transmission member 24, the first linear transmission member 24 compared to the size of the hole 22 may be the smallest linear transmission member. Here, as shown in FIG. 3 , the dimension D1 of the hole 22 in the parallel arrangement direction of the multiple first linear transmission members 24 (the width direction of the first sheet 21) is larger than the diameter D2 of the first linear transmission member 24. The dimension of the hole 22 in the extension direction of the first linear transmission member 24 may be larger than the diameter of the first linear transmission member 24.

[0054] The softening point of the first resin material is higher than the softening point of the second resin material, so that when the first sheet 21 and the second sheet 31 are directly fixed to each other at the contact area, mainly the second resin material can deform.

[0055] In this example, since the first resin material is polyolefin and the second resin material is PVC, it is easy to set the softening point of the first resin material higher than that of the second resin material. The softening points can be adjusted by the degree of polymerization of the resin materials, additives, etc. For example, the softening point of the first resin material may be less than 100 degrees Celsius, and the softening point of the second resin material may be 100 degrees Celsius or higher. The softening point may also be interpreted as the melting point.

[0056] The fixing portions 40 (holes 22) are provided on both side edges along the width direction of the sheet member. Both side edges along the width direction of the sheet member serve as fixing margins for providing the fixing portions 40 (holes 22). The space between the fixing portions 40 (holes 22) on both side edges of the sheet member serves as a wire arrangement portion where a linear transmission member is arranged. The fixing portions 40 (holes 22) may be provided between multiple linear transmission members.

[0057] The fixing portions 40 (holes 22) and the wire fixing portions 50 are provided at multiple locations spaced apart along the extension direction of the linear transmission member. In the example shown in Fig. 1, the fixing portions 40 and the wire fixing portions 50 are located at the same positions along the extension direction of the linear transmission member. The fixing portions 40 and the wire fixing portions 50 may be located at different positions along the extension direction of the linear transmission member.

[0058] 1, the sheet member is provided with fixing margins along the extension direction of the linear transmission member, even at positions where the fixing portions 40 are not provided. The sheet member may be configured so that fixing margins are not provided at positions where the fixing portions 40 are not provided along the extension direction of the linear transmission member. In this case, the fixing margins are formed in the shape of protruding pieces that partially protrude from the wire arrangement portion at the positions where the fixing portions 40 are provided.

[0059] Here, in the wire arrangement portion of the sheet member, the first sheet 21 and the second sheet 31 are not directly fixed to each other at the contact area. Here, in the wire arrangement portion of the sheet member, the first sheet 21 and the second sheet 31 are not in contact with each other.

[0060] At least one of the first linear transmission member 24 and the second linear transmission member 34 may be disposed between the first sheet 21 and the second sheet 31. Here, the second linear transmission member 34 is disposed between the first sheet 21 and the second sheet 31. The first linear transmission member 24 may be disposed between the first sheet 21 and the second sheet 31. Both the first linear transmission member 24 and the second linear transmission member 34 may be disposed between the first sheet 21 and the second sheet 31.

[0061] <Effects, etc.> In the wiring member 10 configured as described above, the first coating layer 26 of the first linear transmission member 24 and the first sheet 21 are made of the same first resin material, allowing for strong direct fixation at their contact points. The second coating layer 36 of the second linear transmission member 34 and the second sheet 31 are made of the same second resin material, allowing for strong direct fixation at their contact points. Because the holes 22 in the first sheet 21 are filled with the second resin material to form the fixing portions 40, the first sheet 21 and the second sheet 31 can be firmly and directly fixed at their contact points even if they are made of different resin materials. This allows for effective fixation of multiple types of linear transmission members with different coating materials through direct fixation at their contact points. Furthermore, because the sheets 21 and 31 can be fixed to each other through direct fixation at their contact points, it is possible to reduce the number of fixing components required for a method other than direct fixation at their contact points. Furthermore, separate sheet members can be prepared for the first sheet 21 and the second sheet 31. This allows for the use of general-purpose sheet members as the first sheet 21 and the second sheet 31, thereby reducing costs.

[0062] Furthermore, the additional sheet portion 42 and the second sheet 31 are directly fixed to each other at the contact area via the hole 22. This allows the strength of the fixing portion 40 to be increased.

[0063] Furthermore, the size of the hole 22 is larger than the diameter of the first linear transmission member 24. This allows the direct fixing area of the contact area between the second sheet 31 and the additional sheet portion 42 to be enlarged, thereby increasing the strength of the fixing portion 40.

[0064] In addition, the softening point of the first resin material is higher than the softening point of the second resin material, which makes it easier for the second resin material to penetrate into the holes 22 of the first sheet 21 while suppressing softening of the peripheral portions of the holes 22 of the first sheet 21.

[0065] In addition, the first resin material is polyolefin and the second resin material is polyvinyl chloride, which makes it easier to firmly integrate the linear transmission member having a polyolefin coating and the linear transmission member having a polyvinyl chloride coating.

[0066] [Embodiment 2] A wiring member according to embodiment 2 will be described. Fig. 4 is a cross-sectional view showing a wiring member 110 according to embodiment 2. Fig. 5 is an enlarged view of region A in Fig. 4. In the description of this embodiment, components similar to those described so far are assigned the same reference numerals, and description thereof will be omitted.

[0067] The wiring member 110 differs from the wiring member 10 in that the additional sheet portion 42 is not provided in the fixing portion 140 of the wiring member 110. In the fixing portion 140, only the first sheet 121 and the second sheet 31 overlap.

[0068] Here, the holes 122 are holes originating from the sheet material that constitutes the first sheet 121. The first sheet 121 is a sheet with a large number of holes 122, and some of the large number of holes 122 are used for the fixing portion 140. The first sheet 121 has holes 122 that are not used for the fixing portion 140. Holes 122 that are not used for the fixing portion 140 are also formed in the wire arrangement portion of the first sheet 121.

[0069] In the example shown in Fig. 5, the first sheet 121 is a nonwoven fabric. The holes 122 are gaps between the fibers 123 that make up the nonwoven fabric. In this case, the softened second resin material enters the gaps between the fibers 123. Some of the fibers 123 are wrapped in the second resin material. The second resin material wrapping the fibers 123 becomes the catch portion 144.

[0070] FIG. 6 is a diagram showing a modified example of the fixing part 140. In the fixing part 140A shown in FIG. 6, the first sheet 121A is a mesh sheet. The holes 122A are holes (mesh) in the mesh sheet. For example, the mesh sheet is composed of a plurality of warp threads 123A and a plurality of weft threads 123B. The portions of the mesh located between the plurality of warp threads 123A and the plurality of weft threads 123B are defined as the holes 122A. The softened second resin material passes through the holes 122A and wraps around the warp threads 123A or weft threads 123B to the side farther from the second sheet 31. Some of the warp threads 123A or weft threads 123B are wrapped in the second resin material. The second resin material wrapping the warp threads 123A or weft threads 123B forms the catch portion 144A.

[0071] The wiring member 110 having such fixing portions 140, 140A can also satisfactorily fix a plurality of types of linear transmission members having different coating materials by directly fixing them at contact portions, similar to the above-described wiring member 10. Furthermore, since the wiring member 110 does not have the additional sheet portion 42, the number of components constituting the fixing portions 140, 140A can be reduced compared to the wiring member 10.

[0072] 5, the holes 122 are gaps between the fibers 123 that make up the nonwoven fabric. In this case, the gaps between the fibers 123 that make up the nonwoven fabric can be used as the holes 122, eliminating the need to separately open holes 122 for the fixing parts 140 in the first sheet 121.

[0073] 6, holes 122A are holes in the mesh sheet. In this case, the holes in the mesh sheet can be used as holes 122A in fixing part 140A as they are, eliminating the need to separately drill holes 122A for fixing part 140A in first sheet 121A.

[0074] [Note] In the above examples, the wiring members 10 and 110 do not include any wiring bodies other than the first wiring body 20 and the second wiring body 30, but this is not a required configuration. For example, as shown in FIG. 7 , the wiring member 210 may include a wiring body 60 other than the first wiring body 20 and the second wiring body 30. A third wiring body 60 having a third linear transmission member 64 may be disposed between the first sheet 21 and the second sheet 31. The third wiring body 60 may include a third sheet 61 to which the third linear transmission member 64 is directly fixed at a contact portion, similar to the first wiring body 20. The third sheet 61 may be fixed to the first sheet 21 and the second sheet 31. The third sheet 61 may not be fixed to the first sheet 21 and the second sheet 31. The third wiring body 60 may not include the third sheet 61. The third wiring body 60 may be held in a stacked state simply by being wrapped between the first wiring body 20 and the second wiring body 30. The third wiring body 60 may be laminated on the outside of the second wiring body 30. In this case, the third sheet 61 may be made of the second resin material, and the third sheet 61 may be directly fixed to the second sheet 31 at the contact portion in the fixing portion 40.

[0075] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually contradictory. [Explanation of symbols]
