[0004] The conditions suitable for fusing a special wire, such as a twisted wire, to a base member are often different from the conditions suitable for fusing an ordinary wire, such as a single-core electric wire, to a base member. For this reason, ordinary wires, such as single-core electric wires, and special wires, such as a twisted wire, are difficult to fuse together to the base member.

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

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

[0011] (1) A wiring member comprising a base member and a wiring body including a normal wire fused to the base member, and a special wire fused to the wiring body via a fixing part, the fixing part being fixed in a fixing manner different from the fusion of the base member and the special wire. Since the fixing part is fixed in a fixing manner different from the fusion of the base member and the special wire, the normal wire and the special wire can be easily fixed to the base member.

[0012] (2) In the wiring member of (1), the fixing portion may include a bundling portion in which the wiring body and the special wire are bound by a bundling material, whereby the special wire can be fixed without fusing.

[0013] (3) In the wiring member of (2), the normal wire and the special wire may be bound by the binding member at the binding portion, whereby the special wire is fixed to the base member via the normal wire fixed to the base member.

[0014] (4) In the wiring member of (3), the side edge of the base member may be recessed, and the portion of the normal wire that passes over the recessed portion of the side edge of the base member may be bound to the special wire. This makes it possible to easily bind the special wire and the normal wire at the middle part of the base member.

[0015] (5) In the wiring member of (3) or (4), a plurality of the normal wires may be arranged in parallel, and some of the parallel normal wires may be bound to the special wire. This allows the special wire to be fixed without wrapping a binding member around the entire periphery of the wiring body.

[0016] (6) In the wiring member of (2), the base member and the special wire may be bound by the binding member at the binding portion, whereby the special wire is fixed to the base member via the binding member.

[0017] (7) In the wiring member of any one of (2) to (6), a plurality of fusion parts between the base member and the normal wire may be provided at intervals in the longitudinal direction of the normal wire, and the bundling part may be provided between the plurality of fusion parts, thereby fixing the special wire at a position of the middle part of the base member.

[0018] (8) In the wiring member of (1), the base member may be a first base member, and the fixing portion may include a fixing portion between the special wire and a second base member different from the first base member, and a fixing portion between the first base member and the second base member. In this way, the special wire is fixed to the wiring body by fixing the first base member to which the normal wire is fixed and the second base member to which the special wire is fixed.

[0019] [Details of the embodiment of the present disclosure] Specific examples of the wiring member of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0020] [Embodiment 1] The wiring member according to the first embodiment will be described below. Fig. 1 is a schematic plan view showing a wiring member 10 according to the first embodiment. Fig. 2 is a partially enlarged view of Fig. 1. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 2. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 2.

[0021] The wiring member 10 includes a wiring body 20 and a special wire 50. The wiring body 20 includes a base member 30 and a normal wire 40. The normal wire 40 is fused to the base member 30.

[0022] The base member 30 may be any member having a placement surface on which the normal line 40 is placed. In the following description, the base member 30 is described as being a sheet 30. The sheet 30 includes a fusion layer 31. The fusion layer 31 includes a resin material, preferably a thermoplastic resin material. The resin material of the fusion layer 31 softens and is fused to the fusion partner. 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 structure of the fusion layer 31 is not particularly limited. For example, the fusion layer 31 may be a sheet having a uniform solid cross section (also called a non-foamed sheet or solid sheet). For example, the fusion layer 31 may be a foamed sheet or the like. For example, the fusion layer 31 may be a fibrous sheet such as a knitted fabric, a woven fabric, or a nonwoven fabric.

[0024] The sheet 30 may have a single-layer structure consisting of a fusion layer 31. The sheet 30 may have a multi-layer structure. When the sheet 30 has a multi-layer structure, it is preferable that the fusion layer 31 appears on at least one main surface of the sheet 30. Here, the sheet 30 includes the fusion layer 31 and an additional layer 32. A normal line 40 is fused to the fusion layer 31. One surface of the fusion layer 31 is set as one main surface of the sheet 30.

[0025] The additional layer 32 may be formed of a different material or have a different structure from the fusion layer 31. The additional layer 32 enhances the function of the fusion layer 31 or adds a function not present in the fusion layer 31 to the sheet 30. The material constituting the additional layer 32 may be a metal or the like in addition to the materials described for the fusion layer 31 above. The structure of the additional layer 32 may be any of the structures described for the fusion layer 31 above. One surface of the additional layer 32 is the other main surface of the sheet 30.

[0026] The fusion layer 31 and the additional layer 32 are fixed while the other surface of the fusion layer 31 and the other surface of the additional layer 32 are in contact with each other. The manner in which the fusion layer 31 and the additional layer 32 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 31 and the additional layer 32 is a sheet having voids on the surface such as a fiber material sheet or a foam sheet, a resin material or an adhesive can be inserted into the voids to fix them. This produces a so-called anchor effect, and the fusion layer 31 and the additional layer 32 are firmly fixed.

[0027] Here, the description will be given assuming that the fusion layer 31 is a solid sheet made of resin, and the additional layer 32 is a fiber material sheet. Here, the description will be given assuming that the fusion layer 31 and the additional layer 32 are fused together. That is, the resin of the fusion layer 31 penetrates between the fibers of the additional layer 32 in a fluid state, and then hardens. This maintains the state in which the resin of the fusion layer 31 penetrates between the fibers of the additional layer 32, and the fusion layer 31 and the additional layer 32 are firmly fixed together.

[0028] The fusion layer 31 and the additional layer 32 are formed to have the same size (same planar shape). One of the fusion layer 31 and the additional layer 32 may be formed larger than the other. The fusion layer 31 and the additional layer 32 are fixed over the entire contact area. The fusion layer 31 and the additional layer 32 may be fixed only in a part of the contact area.

[0029] The sheet 30 may be a soft member. For example, the fusion layer 31 is a resin layer having a uniform solid cross section made of a soft resin such as soft PVC, and the additional layer 32 is a nonwoven fabric made of PET, so that the sheet 30 is a soft member. For example, the sheet 30 may have flexibility capable of following the bending of the normal wire 40. In other words, the wiring member 10 may be capable of bending in the thickness direction (bending such that the folds are along the main surface of the sheet 30).

[0030] The normal wire 40 is a linear member that transmits electricity, light, or the like. The sheet 30 is formed in a flat shape overall. The normal wire 40 is fixed to the sheet 30, thereby maintaining the wiring body 20 in a flat shape. The special wire 50 is also a linear member that transmits electricity, light, or the like. The special wire 50 is fixed to the flat wiring body 20, thereby maintaining the wiring member 10 in a flat shape. The normal wire 40 and the special wire 50 that transmit electricity may be various signal lines or various power lines. Parts of the normal wire 40 and the special wire 50 that transmit electricity may be used as antennas, coils, or the like that send signals or power to or receive power from space.

[0031] Here, the normal wire 40 is described as a single-core electric wire 40, and the special wire 50 is described as a twisted wire 50. The single-core electric wire 40 has one core wire 41 and a coating layer 42 that covers the core wire 41. The core wire 41 is one conductive path composed of one or more strands. The coating layer 42 is formed by extruding a resin material around the core wire 41. The twisted wire 50 is formed by twisting multiple coated electric wires 51. Note that FIG. 3 shows a twisted pair wire as a typical example of the twisted wire 50. Note that the circular range R shown by the two-dot chain line in FIG. 3 indicates the range in which the multiple coated electric wires 51 in the twisted wire 50 move. The same applies to the following figures.

[0032] However, the combination of the normal wire 40 and the special wire 50 is not limited to this. For example, the special wire 50 may be a member that is more difficult to fuse to the sheet 30 than the normal wire 40. The term "more difficult to fuse to the sheet 30 than the normal wire 40" refers to a case where the special wire 50 cannot be fused to the sheet 30, or a case where the special wire 50 can be fused to the sheet 30 but requires more effort to fuse to the sheet 30 than the normal wire 40, or a case where the special wire 50 has a lower fusion strength to the sheet 30 than the normal wire 40 when fused under the same fusion conditions. For example, the special wire 50 has more transmission paths than the normal wire 40, or has a multi-layer structure than the normal wire 40, which makes it more difficult to fuse to the sheet 30 than the normal wire 40. For example, the special wire 50 has a non-uniform cross-sectional shape along its longitudinal direction, and therefore the reaction force when pressed during fusion is not uniform, which makes it more difficult to fuse to the sheet 30 than the normal wire 40. Also, for example, the special wire 50 is more difficult to fuse to the sheet 30 than the ordinary wire 40 because the coating layer of the special wire 50 is made of a material that is more difficult to fuse to the sheet 30 than the coating layer 42 of the ordinary wire 40 .

[0033] Here, in the twisted wire 50, the arrangement of the covered electric wires 51 changes periodically along the longitudinal direction. Therefore, in the twisted wire 50 on the sheet 30, there are periodically portions where the covered electric wires 51 in the twisted wire 50 are stacked vertically on the sheet 30 (hereinafter referred to as vertically arranged portions) and portions where the covered electric wires 51 are arranged horizontally on the sheet 30 (hereinafter referred to as horizontally arranged portions). Even if the vertically arranged portions and the horizontally arranged portions are fused under the same fusion conditions, the fusion strength to the sheet 30 may differ. Also, in the twisted wire 50, it is time-consuming to selectively fuse either the vertically arranged portions or the horizontally arranged portions. For these reasons, it is considered that the twisted wire 50 is more difficult to fuse to the sheet 30 than a single-core electric wire.

[0034] The normal wire 40 and the special wire 50 are assumed to be components that connect components in a vehicle. For example, a connector C is provided at the ends of the normal wire 40 and the special wire 50. The normal wire 40 and the special wire 50 are connected to the counterpart component by connecting the connector C to the 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 connector C may be fixed to the seat 30. In the example shown in FIG. 1, one end of the special wire 50 is incorporated into the same connector C as the connector C into which the end of the normal wire 40 is incorporated. In addition, the other end of the special wire 50 is incorporated into a connector C different from the connector C into which the end of the normal wire 40 is incorporated. However, both ends of the special wire 50 may be incorporated into the same connector C as the connector C into which the end of the normal wire 40 is incorporated. In addition, both ends of the special wire 50 may be incorporated into a connector C different from the connector C into which the end of the normal wire 40 is incorporated.

[0035] The routes of the normal line 40 and the special line 50 are set according to the position of the component to which they are to be connected, etc. By being fixed to the sheet 30, the normal line 40 is kept along a wiring route according to the position of the component to which they are to be connected, etc. The normal line 40 may be fixed to the sheet 30 in a manner in which the branch lines branch off from the main line. The sheet 30 may also be formed in a shape in which the part to which the branch lines are fixed branches off from the part to which the main line is fixed. Here, the normal line 40 branches on the sheet 30. The sheet 30 branches according to the branch shape of the normal line 40. By being fixed to the wiring body 20, the special line 50 is kept along a wiring route according to the position of the component to which it is to be connected, etc.

[0036] In the example shown in FIG. 1, the special line 50 extends along at least one of the normal lines 40 with respect to a portion where the normal line 40 is disposed on the sheet 30. The special line 50 may extend in a direction different from that of the normal line 40 with respect to a portion where the normal line 40 is disposed on the sheet 30. The special line 50 may branch off from another normal line 40. For example, with respect to the sheet 30 in FIG. 1, the normal line 40 may extend between a connector C located on the left side of the branching portion and a connector C located above the branching portion, and the special line 50 may extend between a connector C located on the left side of the branching portion and a connector C located on the right side of the branching portion.

[0037] The portion where the sheet 30 and the normal line 40 are fused is called the fused part WP. Here, a plurality of fused parts WP are provided at intervals in the longitudinal direction of the normal line 40. In the example shown in FIG. 1, the fused parts WP are provided at the ends of the straight sections (boundaries between the straight sections and the curved lines) and at the ends of the sheet 30. Furthermore, when the straight sections are long, the fused parts WP are provided in the middle of the straight sections. In the example shown in FIG. 1, the fused parts WP are not provided in the middle of the curved sections, but may be provided in the middle of the curved sections. However, the fused parts WP may be provided in a continuous manner from one end to the other end of the sheet 30 along the longitudinal direction of the normal line 40.

[0038] The means for forming the fused state between the sheet 30 and the normal line 40 is not particularly limited, and various fusion means such as ultrasonic fusion, heat and pressure fusion, hot air fusion, and high frequency fusion can be used. When the fused state is formed by these means, the fused part WP is in a fused and fixed state by that means. Specifically, for example, when the fused part WP is formed by ultrasonic fusion, the fused part WP becomes an ultrasonic fused part.

[0039] The sheet 30 and the regular wire 40 are fused together by melting the resin material of at least one of them and adhering to the other side. Preferably, the sheet 30 and the regular wire 40 are fused together by melting the resin materials of both of them and adhering to each other. The resin material constituting the fusion layer 31 is preferably the same type as the resin material constituting the covering layer 42. For example, the resin material constituting the fusion layer 31 and the resin material constituting the covering layer 42 may both be PVC.

[0040] The special wire 50 is fixed to the wiring body 20 via fixing parts 12. The fixing parts 12 are fixed in a manner different from the fusion of the sheet 30 and the special wire 50. Here, the fixing parts 12 are bundling parts 12. The bundling parts 12 are the parts where the wiring body 20 and the special wire 50 are bound and fixed by a bundling member 60. Here, the wiring member 10 is provided with a plurality of fixing parts 12 (here, four). All four fixing parts 12 are bundling parts 12. The four fixing parts 12 may include fixing parts other than the bundling parts 12.

[0041] Here, in the bundling portion 12, the normal wire 40 and the special wire 50 are bound by a bundling member 60. In the bundling portion 12, the sheet 30 is not bound to the special wire 50. In the bundling portion 12, of the normal wire 40 and the sheet 30, only the normal wire 40 is bound to the special wire 50. Such a bundling portion 12 may be referred to as a normal wire bundling portion. Here, all four bundling portions 12 are normal wire bundling portions. The four bundling portions 12 may include bundling portions 12 other than normal wire bundling portions (for example, a base member bundling portion or a wiring body fixing portion described below).

[0042] The bundling member 60 may be any member capable of bundling the wiring body 20 (here, the normal wire 40) and the special wire 50. For example, the bundling member 60 may be an adhesive tape or a bundling band. The adhesive tape includes, for example, a base layer and an adhesive layer. The adhesive layer is laminated on one surface of the base layer. The bundling band includes, for example, a band portion and a band fixing portion. The band fixing portion is connected to the base end of the band portion and can fix the tip end of the band portion wrapped around the bundling target. The bundling band may be a bundling band in which the extension direction of the band portion is restricted and the bundling band can be wrapped around the bundling target in a flat position. The bundling band may be a normal bundling band in which the extension direction of the band portion is not restricted. The bundling member 60 may be wrapped around the twisted wire 50, for example, along a circular range R in which the coated electric wire 51 moves.

[0043] Here, in two of the four normal wire binding parts 12, the part of the normal wire 40 that extends outward from the sheet 30 along the longitudinal direction of the sheet 30 is bound in the normal wire binding parts 12a. In two of the four normal wire binding parts 12, the part of the normal wire 40 that is located in the middle of the sheet 30 along the longitudinal direction of the sheet 30 is bound in the normal wire binding parts 12b. The normal wire binding parts 12b are provided between a plurality of fusion parts WP. The four normal wire binding parts 12 are arranged in the order of normal wire binding parts 12a, 12b, 12b, 12a from one end side to the other end side along the longitudinal direction of the special wire 50. Between the two sets of normal wire binding parts 12a, 12b, the normal wire 40 and the special wire 50 extend linearly. Between the two normal wire binding parts 12b, a section in which the normal wire 40 and the special wire 50 are bent is provided. In the example shown in Fig. 1, in the section where the normal wire 40 and the special wire 50 bend, the special wire 50 is located on the outer periphery side of the normal wire 40. In the section where the normal wire 40 and the special wire 50 bend, the special wire 50 may be located on the inner periphery side of the normal wire 40. Instead of the two normal wire binding parts 12b, one normal wire binding part that binds the normal wire 40 and the special wire 50 at a point where they bend may be provided. In other words, the special wire 50 may extend in a curved manner inside the normal wire binding part, and the special wires 50 may extend in directions that cross each other on one side and the other side of the normal wire binding part.

[0044] The regular line binding portion 12b is provided at the position of the recess 33 of the sheet 30. The recess 33 is a portion where the side edge of the sheet 30 is recessed. Here, the recess 33 is recessed along the width direction of the sheet 30 to the portion overlapping with the regular line 40. Therefore, the depth dimension of the recess 33 is larger than the dimension from the regular line 40 closest to the side edge of the sheet 30 along the width direction of the sheet 30 to the said side edge. Also, here, the recess 33 is recessed to the portion between the regular lines 40 parallel to the width direction of the sheet 30. Therefore, the depth dimension of the recess 33 is smaller than the dimension from the regular line 40 farthest from the side edge of the sheet 30 along the width direction of the sheet 30 to the said side edge. The width dimension of the recess 33 (the dimension along the longitudinal direction of the regular line 40) is preferably equal to or larger than the width dimension of the binding member 60 (here, adhesive tape). In the regular line binding portion 12, the portion of the regular line 40 that passes over the recess 33 of the sheet 30 is bound to the special line 50. The bundling member 60 passes through the recess 33 to bundling the regular wire 40 and the special wire 50 together.

[0045] In the wiring member 10, there is a parallel section in which a plurality of normal wires 40 are arranged in parallel. A normal wire bundling section 12 is provided in the parallel section. In the parallel section, some of the parallel normal wires 40 are bundling with the special wire 50. In all four normal wire bundling sections 12, some of the parallel normal wires 40 are bundling with the special wire 50. Such a normal wire bundling section 12 may be referred to as a partial wire bundling section. In some or all of the four normal wire bundling sections 12, all of the parallel normal wires 40 may be bundling with the special wire 50. Such a normal wire bundling section may be referred to as a full wire bundling section.

[0046] The number of normal wires 40 bound in the normal wire binding section 12 may be one or more. When the number of normal wires 40 bound in the normal wire binding section 12 is more than one, the interval between the normal wires 40 in the normal wire binding section 12 may be the same as the interval between the normal wires 40 on the sheet 30 (the interval between the normal wires 40 at the position where the fused portion WP is formed), or may be narrower than that. The normal wires 40 may be arranged at intervals on the sheet 30, and the normal wires 40 may be in contact with each other in the normal wire binding section 12. In the normal wire binding section 12, the special wire 50 and the adjacent normal wire 40 may be in contact with each other or may be separated from each other.

[0047] When the binding member 60 is an adhesive tape, a part of the adhesive tape (a part wound above the special wire 50 and the normal wire 40 in FIG. 3) and another part (a part wound below the special wire 50 and the normal wire 40 in FIG. 3) may be bonded between the special wire 50 and the adjacent normal wire 40. This maintains the special wire 50 and the adjacent normal wire 40 apart. Similarly, a part of the adhesive tape and another part may be bonded between the normal wires 40, so that the normal wires 40 are maintained apart.

[0048] <Effects of the First Embodiment> According to the wiring member 10 configured as described above, the fixing portion 12 is fixed in a fixing manner different from the fusion of the sheet 30 and the special wire 50, so that the regular wire 40 and the special wire 50 can be easily fixed to the sheet 30.

[0049] The fixing portion 12 includes a bundling portion 12 in which the wiring body 20 and the special wire 50 are bound by a bundling member 60. This allows the special wire 50 to be fixed to the wiring body 20 without fusing it.

[0050] In addition, in the binding portion 12, the regular wire 40 and the special wire 50 are bound by the binding member 60. As a result, the special wire 50 is fixed to the sheet 30 via the regular wire 40 fixed to the sheet 30.

[0051] Furthermore, the portion of the regular wire 40 that passes through the recess 33 of the sheet 30 is bound to the special wire 50. This makes it possible to easily bind the special wire 50 and the regular wire 40 in the middle portion of the sheet 30.

[0052] In addition, some of the parallel regular wires 40 are bound to the special wire 50. This allows the special wire 50 to be fixed in place without wrapping the binding member 60 around the entire periphery of the wiring body 20.

[0053] Furthermore, the bundling portion 12 is provided between the plurality of fused portions WP. As a result, the special wire 50 is fixed to the sheet 30 at the intermediate position.

[0054] [Embodiment 2] A wiring member according to embodiment 2 will be described. Fig. 5 is a schematic plan view showing a wiring member 110 according to embodiment 2. Fig. 6 is a cross-sectional view taken along line VI-VI in Fig. 5. In the following description, components similar to those described so far are given the same reference numerals and description thereof will be omitted.

[0055] In wiring member 110, the structure of binding portion 112 differs from the structure of binding portion 12 in wiring member 10. Specifically, in binding portion 112, sheet 130 and special wire 50 are bound by binding member 60. As a result, special wire 50 is fixed to sheet 130 via binding member 60.

[0056] In the bound portion 112, the regular wire 40 is not bound to the special wire 50. In the bound portion 112, of the regular wire 40 and the sheet 130, only the sheet 130 is bound to the special wire 50. Such a bound portion 112 may be referred to as a base material bound portion 112.

[0057] The sheet 130 has a portion for binding the special wire 50 with the binding member 60. Specifically, the sheet 130 has a normal wire arrangement portion 134 and an extension portion 135. The normal wire arrangement portion 134 is a portion where the normal wire 40 is arranged and fixed. The extension portion 135 is a portion extending from the normal wire arrangement portion 134. The normal wire 40 is not fixed to the extension portion 135. Here, the extension portion 135 has a horizontal extension portion 135a and a vertical extension portion 135b. The horizontal extension portion 135a is a portion extending laterally from the normal wire arrangement portion 134. The vertical extension portion 135b is a portion extending from the horizontal extension portion 135a in the longitudinal direction of the horizontal extension portion 135a. The side edge of the vertical extension portion 135b is not connected to the side edge of the normal wire arrangement portion 134. Here, in the bundling portion 112, the special wire 50 is disposed on the extending portion 135 of the sheet 130. The vertical extending portion 135b of the extending portion 135 is bound to the special wire 50. In the sheet 130, the horizontal extending portion 135a continues continuously along the longitudinal direction of the normal line arrangement portion 134. The horizontal extending portions 135a may be provided at a plurality of locations spaced apart along the longitudinal direction of the normal line arrangement portion 134. The extending portion may be formed in a planar shape such as an L-shape or a T-shape so as to have a horizontal extending portion and a vertical extending portion, and may be provided partially along the longitudinal direction of the normal line arrangement portion 134.

[0058] However, as in the following modified example, the special wire 50 does not have to be disposed on the extension portion 135 of the sheet 130.

[0059] FIG. 7 is a schematic plan view showing a modified example of the wiring member 110 according to the second embodiment. FIG. 8 is a cross-sectional view taken along line VIII-VIII in FIG. 7. In the wiring member 210 shown in FIG. 7, the special wire 50 is not arranged on the sheet 230. The special wire 50 is arranged on the side of the sheet 230. The vertical extension portion 235 in the sheet 230 extends in the longitudinal direction from the longitudinal end of the normal wire arrangement portion 134. The vertical extension portion 235 is not fixed to the normal wire 40. In the bundling portion 212, the bundling member 60 binds the vertical extension portion 235 and the special wire 50. A part of the bundling member 60 is located between the normal wire 40 and the vertical extension portion 235. Note that the special wire 50 may be arranged on the side of the extension portion 135 in the sheet 130, and the vertical extension portion 135b may be bound to the special wire 50.

[0060] [Embodiment 3] A wiring member according to embodiment 3 will be described below. Fig. 9 is a schematic plan view showing a wiring member 310 according to embodiment 3. Fig. 10 is a cross-sectional view taken along line XX in Fig. 9.

[0061] The wiring member 310 differs from the wiring members 10, 110, and 210 in that the fixing portions 14 and 16 are not the bundling portions 12, 112, and 212. Specifically, in the wiring member 310, the sheet 330 in the wiring body 20, that is, the sheet 330 to which the normal wire 40 is fused, is the first sheet 330. The special wire 50 is fixed to a second sheet 70 that is different from the first sheet 330. The second sheet 70 is an example of a second base member. The fixing portion 14 between the second sheet 70 and the special wire 50 is called the special wire fixing portion 14. The first sheet 330 and the second sheet 70 are fixed. The fixing portion 16 between the first sheet 330 and the second sheet 70 is called the base member fixing portion 16. Therefore, the fixing portions 14 and 16 in the wiring member 310 include the special wire fixing portion 14 and the base member fixing portion 16. In this manner, the first sheet 330 to which the normal wire 40 is fixed and the second sheet 70 to which the special wire 50 is fixed are fixed together, whereby the special wire 50 is fixed to the wiring body 20.

[0062] The first sheet 330 and the second sheet 70 may be fixed at their side edges. The first sheet 330 has a normal line arrangement portion 134 and a laterally extending portion 335. The second sheet 70 has a special line arrangement portion 71 and a laterally extending portion 72. A base member fixing portion 16 is provided at the portion where the laterally extending portion 335 and the laterally extending portion 72 overlap.

[0063] The special wire fixing portion 14 and the base member fixing portion 16 may have the same fixing manner or different fixing manners. Such fixing manner may be any fixing manner. For example, such fixing manner may be an adhesive portion fixed via an intervening member such as an adhesive or a double-sided adhesive tape. Also, for example, such fixing manner may be a sewn portion sewn with thread. Also, for example, such fixing manner may be a locking portion using a locking part such as a rivet or a stapler. Also, for example, such fixing manner may be a fused portion. Even when a fused portion is adopted as the special wire fixing portion 14, the special wire 50 is fused to a second sheet 70 different from the first sheet 30 to which the normal wire 40 is fused in such a fused portion. Therefore, the special wire 50 and the second sheet 70 can be fused under fusion conditions suitable for the special wire 50 in the fused portion as the special wire fixing portion 14. Therefore, the special wire 50 and the second sheet 70 can be fused more easily than when the regular wire 40 and the special wire 50 are fused to the first sheet 330 together.

[0064] [Note] Although the special wire 50 has been described as being a twisted wire 50, this is not essential. For example, the special wire 50 may be a coaxial wire, an Ethernet cable, an optical fiber cable, or the like. For example, when the covering layer 42 of the normal wire 40 is made of the same resin material as the fusion layer 31, the special wire 50 may be a single-core electric wire having a covering layer made of a material different from that of the fusion layer 31. For example, when the fusion layer 31 and the covering layer 42 of the normal wire 40 are made of PVC, the special wire 50 may be a single-core electric wire having a covering layer made of a material other than PVC. In this case, the resin material constituting the covering layer of the special wire 50 is not particularly limited as long as it is other than PVC, and may be, for example, a polyolefin such as PE or PP, a silicone resin, or a fluororesin such as polytetrafluoroethylene. Such a resin material may be halogen-free. Halogen-free means that chlorine and bromine among halogens are not contained, or even if they are contained, they are contained in small amounts. For example, the International Electrotechnical Commission (IEC) standard defines halogen-free as a material whose chlorine and bromine content is 900 ppm or less, and whose total chlorine and bromine content is 1500 ppm or less. Halogen-free linear transmission components are also called non-halogen wires (for example, non-halogen electric wires in the case of electric wires).

[0065] Although an example in which there is one special wire 50 has been described so far, there may be multiple special wires 50. The multiple special wires 50 may be arranged on only one side of the wiring body 20, as in the above-mentioned wiring member 10. The multiple special wires 50 may be arranged separately on both sides of the wiring body 20.

[0066] So far, examples have been described in which the bundling part 12 is a normal wire bundling part 12 or a base material bundling part 112, but the bundling part 12 may bundling both the normal wire 40 and the sheet 30 with the special wire 50. Such a bundling part 12 may be referred to as a wiring body bundling part. For example, when the wiring body 20 and the special wire 50 are in the positional relationship shown in FIG. 7, the wiring body bundling part may be a bundling part in which the vertical extension part 235 and the two normal wires 40 on the vertical extension part 235 are bound with the special wire 50 by the bundling member 60.

[0067] 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]
