[0018] [Description of Embodiments of the Present Disclosure]

[0019] First, embodiments of the present disclosure will be described by way of examples.

[0020] The wiring component of the present disclosure is as follows.

[0021] (1) A wiring component comprising: a linear transmission component including a transmission line main body and a covering layer covering the transmission line main body; a first sheet material including a first fusion bonding layer in contact with the linear transmission component and provided on one side of the linear transmission component; and a second sheet material including a second fusion bonding layer in contact with the linear transmission component and provided on the other side of the linear transmission component, wherein the covering layer is fusion-bonded to the first fusion bonding layer and the second fusion bonding layer, respectively. By fusing the covering layer to the first sheet material and the second sheet material, respectively, the first sheet material and the second sheet material are simply fixed to both sides of the linear transmission component. Thus, both sides of the linear transmission component are simply protected by the first sheet material and the second sheet material.

[0022] (2) In the wiring component of (1), the first fusion bonding layer and the second fusion bonding layer may be fused to each other on the side of the linear transmission member. This can prevent the linear transmission member from being exposed between the first sheet and the second sheet.

[0023] (3) In the wiring component of (1), the first welding layer and the second welding layer may not be welded together on the side of the linear transmission component. This facilitates the manufacture of the wiring component. Furthermore, even if a welding margin for welding the first sheet and the second sheet is not provided on the side of the linear transmission component, the width of the wiring component can be reduced.

[0024] (4) In any of the wiring components described in (1) to (3), the second sheet may be provided over the entire surface of the first sheet, and the covering layer may be intermittently fused to the first fusion layer and the second fusion layer along the extending direction of the linear transmission component. This allows both sides of the linear transmission component to be protected over a larger area and reduces the number of fusion sites.

[0025] (5) In any one of the wiring components described in (1) to (3), the first sheet may be partially provided with the second sheet. Thus, by providing the second sheet in a necessary portion, an increase in the mass of the wiring component can be suppressed.

[0026] (6) In any of the wiring components described in (1) to (5), the first sheet and the second sheet may be provided in a region including an intersection of the linear transmission component, the coating layer may not be fused to the first fusion layer and the second fusion layer at the intersection, and the coating layer may be fused to the first fusion layer and the second fusion layer at a position avoiding the intersection. This prevents damage to the linear transmission component at the intersection.

[0027] (7) In any of the wiring components described in (1) to (6), another linear transmission component may be welded to the surface of the second sheet opposite to the surface facing the linear transmission component, thereby providing multiple layers of the linear transmission component.

[0028] [Details of the embodiments of the present disclosure]

[0029] Hereinafter, specific examples of the wiring component of the present disclosure will be described with reference to the drawings. However, the present disclosure is not limited to these examples, but is defined by the claims, and is intended to encompass all modifications within the meaning and scope of the claims.

[0030] [Implementation Method 1]

[0031] Hereinafter, the wiring member according to the first embodiment will be described. Figure 1 This is a plan view showing the wiring member 10 according to the first embodiment. Figure 2 It is along Figure 1 A cross-sectional view obtained by cutting along the II-II line.

[0032] The wiring member 10 includes a linear transmission member 20 , a first sheet 30 , and a second sheet 40 .

[0033] The linear transmission component 20 is a linear component that transmits electricity or light. For example, the linear transmission component 20 can be a conventional electric wire having a core wire and a sheath surrounding the core wire, or it can be a shielded wire, an electric cable, an enameled wire, a nichrome wire, an optical cable, or the like. The linear transmission component 20 includes a transmission wire body 21 and a sheath 22. The transmission wire body 21 is the portion that transmits electricity or light. The transmission wire body 21 is equivalent to the conductor core wire in an electric wire and to the core and sheath in an optical cable. The sheath 22 covers the transmission wire body 21. The sheath 22 is formed by extruding a resin material or the like around the transmission wire body 21. The type of resin material is not particularly limited, and polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and the like can be used.

[0034] The linear transmission component 20 for transmitting electricity can also be various signal lines or power lines. A portion of the linear transmission component 20 for transmitting electricity can also be used as an antenna, coil, or other device for transmitting or receiving signals or power into or from space. Furthermore, the linear transmission component 20 can be a single linear element or a composite of multiple linear elements (e.g., a twisted wire or a cable formed by combining multiple linear elements and covering them with a sheath). If the linear transmission component 20 is a cable, the sheath is also included in the coating 22.

[0035] The number of linear transmission components 20 may be at least one, or may be one or more. Here, four linear transmission components 20 are included. When the four linear transmission components 20 need to be distinguished, they may be referred to as linear transmission components 20A, 20B, 20C, and 20D.

[0036] It is assumed that multiple linear transmission components 20 are components that connect components in a vehicle. The ends of the linear transmission components 20 extend from the sheets 30 and 40 and are located outside the sheets 30 and 40. The middle portion of the linear transmission components 20, excluding the ends, is arranged on the sheets 30 and 40. A connector C, for example, is provided at the end of the linear transmission component 20. The linear transmission component 20 is connected to the other component by connecting this connector C to a connector provided on the other side component. In other words, the present wiring component 10 is used as a wiring component 10 that connects various components to each other electrically (or in a manner that enables optical communication) in a vehicle, etc. The ends of the linear transmission components 20 may also be located on the sheets 30 and 40. The connector C may also be fixed to the sheets 30 and 40.

[0037] The first sheet 30 is provided on one side of the linear transmission member 20. The first sheet 30 includes a first welding layer 32. The first welding layer 32 is in contact with the linear transmission member 20. The first welding layer 32 is welded to the outermost cladding layer 22 of the linear transmission member 20.

[0038] Here, the first sheet material 30 has a two-layer structure of a first welding layer 32 and a first additional layer 34. The first sheet material 30 may have a single-layer structure consisting of the first welding layer 32 or a structure of three or more layers.

[0039] One surface of the first welding layer 32 is intended to be in contact with the linear transmission member 20. The first welding layer 32 comprises a resin material, preferably a thermoplastic resin material. The resin material of the first welding layer 32 softens and fuses to the other object being welded. The type of resin material is not particularly limited; PVC, PE, PP, PET, etc. can be used. The resin material of the first welding layer 32 is preferably the same as the resin material of the covering layer 22.

[0040] The structure of the first welding layer 32 is not particularly limited. For example, the first welding layer 32 may be a sheet material having a uniform fill cross-section (also referred to as a non-foamed sheet or a solid sheet). Alternatively, for example, the first welding layer 32 may be a foamed sheet. Alternatively, for example, the first welding layer 32 may be a sheet material made of a fiber material such as a knitted fabric, a woven fabric, or a non-woven fabric.

[0041] The first additional layer 34 is formed from a different material than the first welding layer 32 or has a different structure. The first additional layer 34 enhances the function of the first welding layer 32 or adds a function to the first sheet 30 that the first welding layer 32 does not have. In addition to the materials described above for the first welding layer 32, the first additional layer 34 may also be made of metal or the like. The structure of the first additional layer 34 may also be any of the structures described above for the first welding layer 32. One surface of the first additional layer 34 is the main surface facing outward on the side of the first sheet 30 opposite to the linear transmission member 20.

[0042] The other surface of the first welding layer 32 contacts the other surface of the first additional layer 34, securing the first welding layer 32 and the first additional layer 34. The method for securing the first welding layer 32 and the first additional layer 34 is not particularly limited, but preferably, they are secured by welding or adhesive bonding. For example, if at least one of the first welding layer 32 and the first additional layer 34 is a sheet material having voids in its surface, such as a fiber sheet or a foam sheet, the resin material or adhesive can penetrate the voids and secure the first welding layer 32 and the first additional layer 34. This creates a so-called anchoring effect, firmly securing the first welding layer 32 and the first additional layer 34.

[0043] Here, the first welding layer 32 is described as a solid sheet made of resin, and the first additional layer 34 is a sheet made of fiber material. The first welding layer 32 and the first additional layer 34 are fused together. Specifically, the resin in the first welding layer 32, while still fluid, penetrates between the fibers of the first additional layer 34 and then hardens. This maintains the resin in the first welding layer 32 between the fibers of the first additional layer 34, firmly securing the first welding layer 32 and the first additional layer 34.

[0044] The first welding layer 32 and the first additional layer 34 are formed to be of the same size (same planar shape). Alternatively, one of the first welding layer 32 and the first additional layer 34 may be larger than the other. The entire contact area of the first welding layer 32 and the first additional layer 34 is fixed. Alternatively, only a portion of the contact area of the first welding layer 32 and the first additional layer 34 may be fixed.

[0045] The first sheet 30 can also be a flexible component. For example, the first welding layer 32 can be a resin layer with a uniform filling cross-section made of a soft resin such as soft PVC, and the first additional layer 34 can be a non-woven fabric made of PET, thereby making the first sheet 30 a flexible component. For example, the first sheet 30 can also have flexibility that allows it to follow the bending of the linear transmission component 20. The wiring component 10 can also be able to bend in the thickness direction (such as bending with the fold along the main surface of the first sheet 30) at the portion where the first sheet 30 is provided. However, the first sheet 30 can also be a component that cannot bend in the thickness direction. The first sheet 30 can also be a component that can bend without breaking when bent in the thickness direction. The first sheet 30 can also be a component that cannot be bent without breaking when bent in the thickness direction. The first sheet 30 can also have rigidity that prevents it from following the bending of the linear transmission component 20.

[0046] The second sheet 40 is disposed on the other side of the linear transmission member 20. The second sheet 40 includes a second welding layer 42. The second welding layer 42 is in contact with the linear transmission member 20. The second welding layer 42 is welded to the outermost cladding layer 22 of the linear transmission member 20.

[0047] Here, the sheet material constituting the second sheet material 40 is the same type of sheet material as that constituting the first sheet material 30. The second sheet material 40 has a two-layer structure consisting of a second welding layer 42 and a second additional layer 44. The second welding layer 42 is a layer having the same material and structure as the first welding layer 32. The second additional layer 44 is a layer having the same material and structure as the first additional layer 34. The sheet material constituting the second sheet material 40 may be a different type of sheet material from that constituting the first sheet material 30. The second sheet material 40 may have a single-layer structure consisting of the second welding layer 42 or a structure having three or more layers.

[0048] The first sheet 30 and the second sheet 40 hold the plurality of linear transmission components 20 in an aligned state. This allows the wiring component 10 to be flattened. Furthermore, the first sheet 30 and the second sheet 40 hold the linear transmission components 20 in a state where they extend along a predetermined path. The path of the linear transmission components 20 is the path along which the linear transmission components 20 extend relative to the assembly object (e.g., a vehicle) when the wiring component 10 is assembled into the assembly object. This facilitates the linear transmission components 20 to follow the predetermined path within the vehicle when the wiring component 10 is assembled into the vehicle.

[0049] Here, the path of the linear transmission element 20 includes a bend 23 and a branch 24. The bend 23 is a portion where the plurality of linear transmission elements 20A, 20B, 20C, and 20D bend in parallel. The branch 24 is a portion where some of the linear transmission elements 20A and 20B branch off so as to extend in a direction different from that of the other linear transmission elements 20C and 20D.

[0050] Intersections 25 and 26 are provided where multiple linear transmission components 20 intersect. These intersections 25 and 26 include a repositioning intersection 25 and a branching intersection 26. The repositioning intersection 25 is a portion where the linear transmission components 20A and 20B are intersected to change the order of arrangement. The branching intersection 26 is a portion where a portion of the linear transmission component 20C intersects to branch off from another portion of the linear transmission components 20A and 20B.

[0051] Here, the first sheet 30 is shaped to follow the path of the linear transmission member 20. Specifically, the first sheet 30 has a portion that curves corresponding to the curved portion 23 of the linear transmission member 20. Furthermore, the first sheet 30 has a portion that branches corresponding to the branched path of the linear transmission member 20. The first sheet 30 may also be formed into a relatively large square shape, for example.

[0052] Here, the planar shape of the second sheet 40 is different from the planar shape of the first sheet 30. The second sheet 40 is partially provided on the first sheet 30. Specifically, the second sheet 40 includes a plurality of sheet portions 41. With respect to the first sheet 30, the plurality of sheet portions 41 are provided to cover mutually different planar areas. The plurality of sheet portions 41 are provided at intervals. Figure 1 In the example shown, five sheet sections 41A, 41B, 41C, 41D, and 41E are provided. Each sheet section 41 is provided in a straight portion. The sheet section 41 is provided to avoid the curved portion 23. No sheet section 41 is provided at the curved portion 23. The sheet section 41 is provided to avoid the intersections 25 and 26. No sheet section 41 is provided at the intersections 25 and 26.

[0053] The sheet portions 41A and 41B are provided on both sides of the curved portion 23. The sheet portions 41C and 41D are provided on both sides of the replacement intersection portion 25. The sheet portions 41B, 41C, and 41E are provided on both sides of the branch portion 24.

[0054] The coating layer 22 is welded to the first welding layer 32 and the second welding layer 42. The coating layer 22 is welded to the first welding layer 32 and the second welding layer 42 intermittently along the extending direction of the linear transmission member 20. Figure 1 、 Figure 2In the figure, the portion where the coating layer 22 is fused to the first fusion layer 32 is shown as fusion portion WP1, and the portion where the coating layer 22 is fused to the second fusion layer 42 is shown as fusion portion WP2. Weld portion WP1 and WP2 are located at the same position along the extension direction of the linear transmission member 20. The linear transmission member 20 is fused to the second fusion layer 42 on the opposite side of the portion fused to the first fusion layer 32. Weld portions WP1 and WP2 are provided at the ends of each sheet portion 41.

[0055] The means for forming the above-mentioned welded state is not particularly limited. For example, the linear transmission member 20 and the first sheet 30 and the second sheet 40 may also be welded by ultrasonic welding. Ultrasonic welding, for example, Figure 2 As shown, with the workpieces clamped between a horn 80 and anvil 82 in an ultrasonic welding machine, frictional heat generated by ultrasonic vibrations applied to the workpieces from the horn 80 melts the resin, etc., resulting in fusion. In addition, various welding methods can be employed, such as heat and pressure welding, hot air welding, and high-frequency welding. Furthermore, when these methods are used to achieve a fusion bond, the linear transmission member 20 and the first and second sheets 30, 40 are fused and fixed together by these methods. Specifically, for example, when ultrasonic welding is used to bond the linear transmission member 20 to the first and second sheets 30, 40, the welded portions WP1 and WP2 become ultrasonic welds.

[0056] The first fusion layer 32 and the second fusion layer 42 are not fused together on the side of the linear transmission member 20. The side of the linear transmission member 20 refers to the portion located further outward in the parallel direction than the two outermost linear transmission members 20 in the parallel direction of the plurality of linear transmission members 20. The first fusion layer 32 and the second fusion layer 42 are not in contact on the side of the linear transmission member 20.

[0057] Here, the plurality of linear transmission members 20 are arranged at intervals along the parallel direction. Alternatively, the plurality of linear transmission members 20 may be arranged in parallel in a contacted state without being spaced apart along the parallel direction.

[0058] Here, the first welding layer 32 and the second welding layer 42 are not welded between the linear transmission members 20. The first welding layer 32 and the second welding layer 42 are not in contact between the linear transmission members 20. The first welding layer 32 and the second welding layer 42 may be in contact between the linear transmission members 20. The first welding layer 32 and the second welding layer 42 may be welded between the linear transmission members 20.

[0059] <Effects of Embodiment 1, etc.>

[0060] According to the wiring member 10 constructed as described above, the first sheet 30 and the second sheet 40 are easily fixed to both sides of the linear transmission member 20 by welding the coating layer 22 to the first sheet 30 and the second sheet 40. Thus, both sides of the linear transmission member 20 are easily protected by the first sheet 30 and the second sheet 40.

[0061] Furthermore, the first welding layer 32 and the second welding layer 42 are not welded together on the sides of the linear transmission member 20. This facilitates the manufacture of the wiring member 10. Furthermore, it is not necessary to provide a welding margin on the sides of the linear transmission member 20 for welding the first sheet 30 and the second sheet 40 together, thereby reducing the width of the wiring member 10.

[0062] In addition, the second sheet 40 is partially provided on the first sheet 30. Thus, by providing the second sheet 40 at a necessary portion, an increase in the mass of the wiring member 10 can be suppressed.

[0063] [Implementation Method 2]

[0064] The wiring component according to the second embodiment will be described. Figure 3 1 is a plan view showing a wiring member 110 according to Embodiment 2. In the following description, the same components as those described above are denoted by the same reference numerals, and description thereof will be omitted.

[0065] The portion of the wiring component 110 in this example where the second sheet 140 is provided differs from the portion of the second sheet 40 provided in the aforementioned wiring component 10. The second sheet 140 includes a single sheet portion 141. The sheet portion 141 is provided in the region including the intersections 25 and 26. Therefore, the first sheet 30 and the second sheet 140 are provided in the region including the intersections 25 and 26 of the linear transmission component 20.

[0066] At the relocation intersection 25, the cladding layer 22 is not fused to the first and second fusion layers 32 and 42. At locations avoiding the relocation intersection 25, the cladding layer 22 is fused to the first and second fusion layers 32 and 42. At the branch intersection 26, the cladding layer 22 is not fused to the first and second fusion layers 32 and 42. At locations avoiding the branch intersection 26, the cladding layer 22 is fused to the first and second fusion layers 32 and 42. Therefore, at the intersections 25 and 26, the cladding layer 22 is not fused to the first and second fusion layers 32 and 42. At locations avoiding the intersections 25 and 26, the cladding layer 22 is fused to the first and second fusion layers 32 and 42. This prevents damage to the linear transmission member 20 at the intersections 25 and 26.

[0067] Furthermore, in the wiring member 110 , a weld portion WP1 is provided in a region where the first sheet 30 is provided and the second sheet 40 is not provided. The position of the weld portion WP1 in the wiring member 110 is the same as that in the wiring member 10 .

[0068] [Implementation Method 3]

[0069] The wiring component according to the third embodiment will be described. Figure 4 This is a plan view showing a wiring member 210 according to the third embodiment.

[0070] In the wiring component 210 of this example, the planar shape of the second sheet material 240 differs from the planar shapes of the second sheets 40 and 140 in the wiring components 10 and 110 described above. Here, the second sheet material 240 is provided over the entire surface of the first sheet material 30. The first sheet material 30 and the second sheet material 240 have the same planar shape. In this case, the covering layer 22 is intermittently fused to the first fusion layer 32 and the second fusion layer 42 along the extension direction of the linear transmission component 20. This protects both sides of the linear transmission component 20 over a wider area and reduces the number of welded areas.

[0071] Here, the first sheet 30 and the second sheet 240 are placed in a region including the curved portion 23 of the linear transmission member 20. At the curved portion 23, the cladding layer 22 is not fused to the first fusion layer 32 and the second fusion layer 42. At locations away from the curved portion 23, the cladding layer 22 is fused to the first fusion layer 32 and the second fusion layer 42. At locations on both sides of the curved portion 23, the cladding layer 22 is fused to the first fusion layer 32 and the second fusion layer 42.

[0072] The positions of the welded portions WP1 and WP2 in the wiring component 210 are the same as those in the wiring component 10. In this example, the welded portions WP1 and WP2 are not provided at the intersections 25 and 26, but are provided at positions avoiding the intersections 25 and 26 (here, at the ends of the straight portions).

[0073] [Implementation 4]

[0074] The wiring component according to the fourth embodiment will be described. Figure 5 This is a cross-sectional view showing a wiring member 310 according to the fourth embodiment.

[0075] The wiring component 310 of this example is different from the wiring components 10, 110, and 210 described above in that the first sheet 330 and the second sheet 340 are welded together. The first sheet 330 and the second sheet 340 have portions that protrude to the side of the linear transmission component 20. This protruding portion is set as a welding margin. On the side of the linear transmission component 20, the first welding layer 32 and the second welding layer 42 at the welding margin are welded together. The welding portion WP3 of the first welding layer 32 and the second welding layer 42 is provided on the side of the linear transmission component 20. Thus, it is possible to suppress the linear transmission component 20 from being exposed between the first sheet 330 and the second sheet 340. Figure 5 In the embodiment, the fusion bond WP3 is provided on both sides of the linear transmission member 20. The fusion bond WP3 may be provided on only one side of the linear transmission member 20.

[0076] The weld portion WP3 may be provided continuously along the entire extension direction of the linear transmission member 20. The weld portion WP3 may also be provided intermittently along the extension direction of the linear transmission member 20, similarly to the weld portions WP1 and WP2. In this case, the weld portion WP3 may be provided at the same position as the weld portions WP1 and WP2, or at a different position.

[0077] The first sheet 330 and the second sheet 340 are not welded between the linear transmission members 20. The first sheet 330 and the second sheet 340 may be welded between the linear transmission members 20.

[0078] [Implementation 5]

[0079] The wiring component according to the fifth embodiment will be described. Figure 6 This is a cross-sectional view showing a wiring member 410 according to the fifth embodiment.

[0080] The wiring member 410 of this example is different from the above-mentioned wiring members 10 , 110 , 210 , and 310 in that it further includes another linear transmission member 50 .

[0081] The other linear transmission component 50 is welded to the surface of the second sheet 440 opposite to the surface facing the linear transmission component 20. Thus, the linear transmission components 20 and 50 are provided in multiple layers. Specifically, the other linear transmission component 50 includes a transmission line body 51 and a coating layer 52, similar to the linear transmission component 20. In addition, a welding layer is provided on the surface of the second sheet 440 that contacts the other linear transmission component 50. Figure 6In the illustrated example, the second sheet material 440 has a three-layer structure consisting of a second fusion layer 42, a second additional layer 44, and a third fusion layer 46. The cover layer 52 of another linear transmission component 50 is fused to the third fusion layer 46. Alternatively, the second sheet material 440 may have a single-layer structure consisting of the second fusion layer 42, with the linear transmission components 20 and 50 fused to both surfaces of the second fusion layer 42.

[0082] The second sheet 440 may cover a portion of the first sheet 30 similarly to the second sheets 40 and 140 , or may cover the entire surface of the first sheet 30 similarly to the second sheet 240 .

[0083] exist Figure 6 In the illustrated example, the other linear transmission components 50 are positioned between or to the sides of the linear transmission components 20, so as not to overlap. The weld WP4 between the cladding layer 52 and the third weld layer 46 of the other linear transmission components 50 is offset from the welds WP1 and WP2 along the direction in which the linear transmission components 20 are arranged. Alternatively, the other linear transmission components 50 may be positioned so as to overlap the linear transmission components 20. Alternatively, the weld WP4 may be located at the same position as the welds WP1 and WP2 along the direction in which the linear transmission components 20 are arranged.

[0084] The number of the other linear transmission components 50 is less than the number of the linear transmission components 20. The number of the other linear transmission components 50 may be the same as or greater than the number of the linear transmission components 20.

[0085] The paths of the linear transmission member 20 and the other linear transmission member 50 can be appropriately set. The other linear transmission member 50 may extend along the same path as the linear transmission member 20. The other linear transmission member 50 may also extend along a different path from the linear transmission member 20. For example, the other linear transmission member 50 may extend along the same path as the linear transmission member 20 in a portion of the path and along a different path from the linear transmission member 20 in another portion of the path. The linear transmission member 20 and the other linear transmission member 50 may be welded to the second sheet 440 at least in the portion where they extend along the same path.

[0086] One end and the other end of the other linear transmission component 50 may be connected to the same connector C as the one end and the other end of the linear transmission component 20. One end and the other end of the other linear transmission component 50 may be connected to connectors different from the one end and the other end of the linear transmission component 20. One end of the other linear transmission component 50 may be connected to the same connector C as the one end of the linear transmission component 20, while the other end of the other linear transmission component 50 may be connected to a connector different from the other end of the linear transmission component 20.

[0087] exist Figure 6 In the example shown, the other linear transmission members 50 are exposed on the side opposite to the second sheet 440. A third sheet may be provided to cover the other linear transmission members 50 from the side opposite to the second sheet 440. The third sheet may be welded to the other linear transmission members 50.

[0088] [Modification]

[0089] The welded portions WP1 and WP2 have been described as being intermittently provided along the extending direction of the linear transmission member 20 , but this is not an essential configuration. The welded portions WP1 and WP2 may be provided continuously over the entire linear transmission member 20 in the extending direction.

[0090] The above-mentioned wiring components 10 can also be connected laterally to form a wiring module. For example, the first sheets 30 or the second sheets 40 of the multiple wiring components 10 can be welded to each other. The type of linear transmission components can also be different between one wiring component and another wiring component among the multiple connected wiring components. For example, multiple thin linear transmission components can be arranged in one wiring component, and multiple thick linear transmission components can be arranged in another wiring component. In this way, the thickness of the linear transmission components is made consistent for each wiring component, so that the first welding layer 32 and the second welding layer 42 can be in good contact with the linear transmission components. In addition, for example, a linear transmission component with a PVC coating layer can be arranged in one wiring component, and a linear transmission component with a polyolefin coating layer can be arranged in another wiring component. In this way, the material of the coating layer of the linear transmission component is made consistent for each wiring component. Furthermore, in each wiring member, the first welding layer 32 and the second welding layer 42 are formed of a material corresponding to the coating layer, and thus can be well welded to the linear transmission member.

[0091] Furthermore, the configurations described in the above-mentioned embodiments and modifications can be appropriately combined as long as they do not contradict each other.
