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

[0019] First, embodiments of the present disclosure will be listed and described.

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

[0021] (1) A wiring component includes: a linear transmission component, a sheet component including a main surface on which the linear transmission component is disposed, and at least one adhesive tape component having one main surface as an adhesive surface. In a state where the adhesive surface faces the linear transmission component side, the at least one adhesive tape component surrounds the linear transmission component, and the at least one adhesive tape component extends outward from the linear transmission component and is adhered to the sheet component through the adhesive surface.

[0022] According to this wiring component, in a state where the adhesive surface faces the linear transmission component side, the at least one adhesive tape component surrounds the linear transmission component, so that the at least one adhesive tape component is firmly adhered to the linear transmission component. Since the adhesive tape component is adhered to the sheet component through the adhesive surface, the linear transmission component can be easily and firmly held on the sheet component.

[0023] (2) According to the wiring component of (1), the at least one adhesive tape component is wound around the linear transmission component. The adhesive tape component can be easily adhered to the linear transmission component.

[0024] (3) According to the wiring component of (2), the at least one adhesive tape component includes a side extension portion that extends outward from the linear transmission component and causes the adhesive surfaces to adhere to each other. By arranging the side extension portion along the main surface of the sheet component, the linear transmission component can be stably arranged on the sheet component.

[0025] (4) The wiring component according to (1) may also be such that at least one of the adhesive tape components includes a first adhesive tape component and a second adhesive tape component. The linear transmission component is disposed between the first adhesive tape component and the second adhesive tape component. On both outer sides of the linear transmission component, the adhesive surfaces of the first adhesive tape component and the second adhesive tape component are bonded to each other. The first adhesive tape component extends from the second adhesive tape component and is bonded to the sheet component. On both outer sides of the linear transmission component, a portion formed by bonding the adhesive surface of the first adhesive tape component and the adhesive surface of the second adhesive tape component is disposed along the main surface of the sheet component, thereby stably disposing the linear transmission component on the sheet component.

[0026] (5) In the wiring component according to any one of (1) to (4), at least one of the adhesive tape components extends outward from the linear transmission component and is wound around the sheet component. Since at least one of the adhesive tape components extends outward from the linear transmission component and is wound around the sheet component, the linear transmission component is more reliably held on the sheet component.

[0027] (6) The wiring component according to any one of (1) to (5) may further include a fused linear transmission component fused to the sheet component. For example, regarding a fused linear transmission component suitable for fusion, it is fused to the sheet component, and regarding a linear transmission component not suitable for fusion, it can be held on the sheet component by at least one adhesive tape component. As a result, a thinner wiring component in which a fused linear transmission component suitable for fusion and a linear transmission component not suitable for fusion coexist can be achieved.

[0028] (7) In the wiring component according to (6), the fused linear transmission component may be fused to the sheet component via a plurality of local fusion portions. The wiring component further includes an auxiliary adhesive component, and the auxiliary adhesive component is bonded to the fused linear transmission component and the sheet component in such a manner as to press between the plurality of fusion portions in the fused linear transmission component. The auxiliary adhesive component presses and holds between the plurality of fusion portions in the fused linear transmission component against the sheet component.

[0029] (8) In the wiring component according to any one of (1) to (7), at least one of the adhesive tape components is disposed at a position where a portion of the linear transmission component extending from the sheet component can be held on the sheet component. The portion of the linear transmission component extending from the sheet component is firmly held by at least one of the adhesive tape components.

[0030] (9) The wiring component according to (8), wherein at least one of the adhesive tape components surrounds the linear transmission component at a position inside the sheet component and closer to the inside than the edge from which the linear transmission component extends. At least one of the adhesive tape components can hold the linear transmission component without protruding from the edge of the sheet component from which the linear transmission component does not extend.

[0031] [Details of Embodiments of the Present Disclosure]

[0032] Hereinafter, specific examples of the wiring component of the present disclosure will be described with reference to the drawings. In addition, the present disclosure is not limited to these examples, but is represented by the claims and is intended to include all modifications within the meaning equivalent to the claims and within the scope.

[0033] [Embodiment]

[0034] Hereinafter, the wiring component according to the embodiment will be described. Figure 1 It is a top view showing the wiring component 10. Figure 2 is Figure 1 A cross-sectional view taken along line II-II in. The wiring component 10 includes: a sheet component 20, a linear transmission component 30, and at least one adhesive tape component 50.

[0035] The sheet component 20 is a sheet-like component. The sheet component 20 includes a main surface 22 on one side and a main surface 24 on the side opposite to the main surface 22. In the present embodiment, the linear transmission component 30 is held on the main surface 22.

[0036] The sheet component 20 may be formed in a shape along the wiring path of the linear transmission component 30. Here, the sheet component 20 is formed in a rectangular shape that is long in one direction. The sheet component may be bent. The sheet component may have a portion that is curved in a curved shape. The sheet component may have a branch portion.

[0037] The material constituting the sheet component 20 is not particularly limited, and the sheet component 20 may be formed of a material including resins such as PVC (polyvinyl chloride), PET (polyethylene terephthalate), and PP (polypropylene). The sheet component 20 may be a sheet filled uniformly inside, or a non-woven fabric board or the like. The sheet component 20 may sometimes contain materials such as metal.

[0038] The sheet member 20 preferably has flexibility that allows it to be easily bent in the thickness direction. For example, the sheet member 20 may also have a property such that it is flexible enough to bend along the shape of the portion where the linear transmission member 30 is to be disposed. Additionally, for example, the sheet member 20 may also have a property such that it is flexible enough to bend in a folding manner. The sheet member 20 may be either a single layer or multiple layers stacked. In the case of multiple layers being stacked, for example, it is conceivable that the sheet member 20 stacks a resin layer and a resin layer. More specifically, for example, it is conceivable that the sheet member 20 stacks a resin sheet uniformly filled inside and a non-woven fabric board. Additionally, for example, it is conceivable that the sheet member 20 stacks a resin layer and a metal layer.

[0039] The linear transmission member 30 is envisioned as a linear transmission member that connects between components in a vehicle in a manner that enables communication or power supply. The linear transmission member 30 is disposed on the main surface 22 side in a manner that extends along a wiring path corresponding to the position of the component to be connected and the like.

[0040] More specifically, the linear transmission member 30 may be a linear member that transmits electricity, light, etc. For example, the linear transmission member 30 may be a general electric wire having a core wire and a covering portion around the core wire, or may be a bare wire, a shielded wire, a stranded wire, an enameled wire, a nichrome wire, an optical fiber, etc.

[0041] As the linear transmission member 30 that transmits electricity, it may also be various signal lines, various power lines. A part of the linear transmission member that transmits electricity, etc. may also be used as an antenna, a coil, etc. that sends or receives signals or power to or from space.

[0042] Additionally, the linear transmission member 30 may be either a single linear object or a composite of multiple linear objects (such as a stranded wire, a cable formed by aggregating multiple linear objects and covering them with a sheath).

[0043] In the present embodiment, a case where the linear transmission member 30 is a shielded cable 30 that transmits electricity will be described. More specifically, the shielded cable 30 includes: a plurality of electric wires 32, a shielding layer 35 that covers the plurality of electric wires, and a sheath 36 that covers the shielding layer 35. The electric wire 32 includes a core wire 33 and a covering portion 34 that covers the periphery of the core wire 33. A plurality (here, two) of electric wires 32 are stranded. The shielding layer 35 has conductivity and covers the stranded electric wires 32. The shielding layer 35 is, for example, a braided fabric formed by braiding metal wires into a tubular shape. The sheath 36 is an insulating layer and is formed by extruding molten resin to cover the periphery of the shielding layer 35. The shielding layer 35 may be omitted. The above shielded cable 30 may also be used, for example, as a microphone connection cable, an antenna cable, a video signal transmission cable, an LVDS (Low Voltage Differential Signaling) signal cable, or the like.

[0044] In addition, in the present embodiment, the wiring member 10 includes a fused linear transmission member 40. The fused linear transmission member 40 is a linear member that transmits electricity, light, or the like, similar to the above-described linear transmission member 30. Here, a case where the fused linear transmission member 40 is an electric wire 40 that transmits electricity will be described. More specifically, the electric wire 40 includes a core wire 41 and a covering portion 43 that covers the periphery of the core wire 41. In the present embodiment, the wiring member 10 includes a plurality (here, four) of electric wires 40. In addition, the fused linear transmission member (electric wire) 40 may be omitted.

[0045] The electric wire 40 is fused to the main surface 22 of the sheet member 20. Here, fusing means fixing by closely adhering by melting at least one of the resin contained in, for example, the linear member (electric wire) 40 and the main surface 22 of the sheet member 20. When performing the above fusing, the resin is considered to melt, for example, by heat or by a solvent. That is, the fused fixing portion achieved by fusing may be in a state of being fused and fixed by heat or in a state of being fused and fixed by a solvent.

[0046] Fusing achieved by heat can be performed by ultrasonic fusing, heat and pressure fusing, hot air fusing, high-frequency fusing, or the like. For example, the fused portion achieved by ultrasonic fusing may also be referred to as an ultrasonic fused portion.

[0047] At the fusing portion, only the surface of the linear member (electric wire) 40 may melt, only the main surface 22 of the base member (sheet member) 20 may melt, or the resin of both of these two may melt.

[0048] Since the wire 40 is welded to the sheet member 20, the surface material of the wire 40 only needs to be a material that can be welded to the main surface 22 of the sheet member 20. For example, the material of the main surface 22 of the sheet member 20 and the surface (coating portion 43) material of the wire 40 may also contain the same resin material. For example, when the main surface 22 of the sheet member 20 is formed of a material containing PVC, the surface material of the wire 40 may also be a material containing PVC.

[0049] The shielded cable 30 is disposed on the main surface 22 along a constant path. Here, the shielded cable 30 is disposed in such a manner as to go from one end portion to the other end portion of the sheet member 20 along the extending direction of the sheet member 20. Here, the shielded cable 30 is disposed linearly along the extending direction of the sheet member 20.

[0050] The wire 40 extends on the main surface 22 along the shielded cable 30. Here, a plurality of wires 40 are dispersedly disposed on both sides of the shielded cable 30. A gap is provided between the plurality of wires 40. A gap is also provided between the wire 40 and the shielded cable 30. The wire 40 and the shielded cable 30 may also be in contact. The wires 40 may also be in contact with each other.

[0051] It is not necessary for the wire 40 to be disposed along the shielded cable 30. The wire 40 may also be welded to the main surface 22 in such a manner as to follow a path different from that of the shielded cable 30.

[0052] The end portions of the shielded cable 30 and the wire 40 may also be connected to the connectors 60, 62. Here, the connector 60 is provided at a position away from one end portion of the sheet member 20, and the connector 62 is provided at a position away from the other end portion of the sheet member 20. The connectors 60, 62 may also be fixed to the sheet member 20. One end portion of the shielded cable 30 (here, one end portion of the plurality of wires 32) and one end portion of the wire 40 extend from the end portion of the sheet member 20 and are connected to the same connector 60. The other end portion of the shielded cable 30 (here, the other end portion of the plurality of wires 32) and the other end portion of the wire 40 extend from the end portion of the sheet member 20 and are connected to the same connector 62.

[0053] At least one adhesive tape member 50 is a member for holding the shielded cable 30 on the main surface 22. Figure 1In this case, at least one adhesive tape member 50 is respectively disposed at a plurality of positions (here, two positions) spaced apart in the extending direction of the shielded cable 30. In the present embodiment, at least one adhesive tape member 50 refers to one adhesive tape member 50. One main surface of the adhesive tape member 50 is an adhesive surface 50f. Here, adhesion means adhesion to an object by applying pressure. More specifically, adhesion means pressing the surface of a viscous liquid or gel etc. against an object and adhering to the uneven surface of the object, whereby the surface adheres to the object. The adhesive surface 50f is a surface having the property of performing such adhesion. The adhesive tape member 50 having the above-mentioned adhesive surface 50f can adhere to the surface of the sheet member 20 and the surface of the shielded cable 30 mainly by a mechanical adhesive force achieved by an anchoring effect etc. Therefore, regardless of the chemical adhesion compatibility between the adhesive surface 50f and the surface materials of the sheet member 20 and the shielded cable 30, the adhesive tape member 50 can adhere to both the main surface 22 of the sheet member 20 and the surface of the shielded cable 30. The above-mentioned adhesive tape member 50 may also be an adhesive tape (so-called PVC tape) in which an adhesive layer is formed on one main surface of a strip-shaped base material formed of PVC etc.

[0054] At least one adhesive tape member 50 holds the shielded cable 30 on the sheet member 20 through the following structure. That is, in a state where the adhesive surface 50f faces the shielded cable 30 side, at least one adhesive tape member 50 becomes a state of surrounding the shielded cable 30. In addition, at least one adhesive tape member 50 extends outward from the shielded cable 30 and adheres to the sheet member 20 through the adhesive surface 50f.

[0055] In the present embodiment, the adhesive tape member 50 winds around the shielded cable 30 with the adhesive surface 50f facing inward. The adhesive tape member 50 may wind around the shielded cable 30 more than one turn. The adhesive tape member 50 may wind around the shielded cable 30 more than 3 / 2 turns or may wind around the shielded cable 30 more than two turns. In the portion of the adhesive tape member 50 wound around the shielded cable 30 by an amount equivalent to one turn, the adhesive surface 50f adheres to the outer peripheral surface of the shielded cable 30. The portion of the adhesive tape member 50 exceeding one turn with respect to the shielded cable 30 overlaps the outward-facing surface of the already wound portion of the shielded cable 30 and adheres to the outward-facing surface. Thereby, the state of winding the adhesive tape member 50 around the shielded cable 30 is held more reliably.

[0056] The one end side portion of the adhesive tape member 50 is wound around the shielded cable 30 as described above. The other end side portion of the adhesive tape member 50 extends outward from the shielded cable 30 and adheres to the sheet member 20. The other end side portion of the adhesive tape member 50 may also wind around the sheet member 20.

[0057] In the present embodiment, the shielded cable 30 is located at the middle portion in the width direction of the sheet member 20. The other end side portion of the adhesive tape member 50 is on the main surface 22 and extends along the width direction of the sheet member 20 from the shielded cable 30. The adhesive tape member 50 reaches one side edge portion of the sheet member 20, and at this one side edge portion, it is turned over toward the other main surface 24 side. The adhesive tape member 50 extends along the width direction of the sheet member 20 on the other main surface 24 and reaches the other side edge portion of the sheet member 20. The adhesive tape member 50 is turned over toward the one main surface 22 side at the other side edge portion of the sheet member 20. The adhesive tape member 50 further extends along the width direction of the sheet member 20 on the main surface 22 and reaches the shielded cable 30. Thus, the other end side portion of the adhesive tape member 50 winds around the sheet member 20 more than once and reaches the shielded cable 30 again. The adhesive tape member 50 may wind around the sheet member 20 more than once.

[0058] On the other end side portion of the adhesive tape member 50, the adhesive surface 50f faces inward. Thus, the adhesive surface 50f adheres to the two main surfaces 22 and 24 of the sheet member 20. Therefore, the other end side portion of the adhesive tape member 50 is firmly adhered to the sheet member 20. In addition, at the place where the electric wire 40 exists on the main surface 22, the adhesive tape member 50 also adheres to the outer periphery of the electric wire 40. Therefore, the adhesive tape member 50 can also function to press the electric wire 40 against the sheet member 20. In addition, the other end portion of the adhesive tape member 50 reaches the shielded cable 30 and adheres to the portion of the one end side portion of the adhesive tape member 50 that has been wound around the shielded cable 30. Thus, the shielded cable 30 is held from both sides by the adhesive tape member 50 adhered to the main surface 22, and the shielded cable 30 is firmly held on the main surface.

[0059] Since it is sufficient that at least a part of the adhesive tape member 50 adheres to the sheet member 20, it is not necessary for the adhesive tape member 50 to be wound around the sheet member 20. In addition, it is not necessary for the other end side portion of the adhesive tape member 50 to wind around once and reach the shielded cable 30 again. In addition, it is not necessary for the adhesive tape member 50 to adhere to the electric wire 40.

[0060] As described above, the structure in which a shielding cable 30, which is an example of a linear transmission component, is held to a sheet component 20 by at least one adhesive tape component 50 can also be applied to a case where it is difficult to weld a shielding cable 30, which is an example of a linear transmission component, to the main surface 22. For example, it is a case where the surface material of a wire 40, which is an example of a linear transmission component (here, the material of the coating portion 43), has the following property in relation to the surface material of the shielding cable 30 (here, the material of the sheath 36) and the surface material of the main surface 22. This property is a case where the peel strength of the wire 40 achieved by welding with respect to the main surface 22 is greater than the peel strength of the shielding cable 30 achieved by welding with respect to the main surface 22. The peel strength can also be evaluated in the following manner. For example, the shielding cable 30 and the wire 40 are welded to the sheet component 20 under the same conditions. For example, the shielding cable 30 and the wire 40 are ultrasonically welded to the sheet component 20 under the same pressing force, pressing time, and vibration conditions. And, the same type of peel test (for example, a test according to a certain test specified in JIS K6854) is performed on the shielding cable 30 and the wire 40 from the sheet component 20 to evaluate the peel strength. For example, a 180° peel test in which the shielding cable 30 or the wire 40 is folded 180° with respect to the sheet component 20 and pulled, or a T-peel test in which the sheet component 20 and the shielding cable 30 or the wire 40 are pulled in a vertical direction opposite to each other with respect to the welding surface, etc. are performed. The magnitude of the peel strength is evaluated by performing the same test on the shielding cable 30 and the wire 40.

[0061] The above difference in peel strength may also be caused by the combination of the constituent material of the main surface and the surface materials of the wire 40 and the shielding cable 30. For example, in the case where the main surface 22 is formed of a material containing PVC, consider the case where the coating portion 43 of the wire 40 is formed of a material containing PVC and the sheath 36 of the shielding cable 30 is formed of a resin not containing PVC, such as a material containing PET (polyethylene terephthalate), PP (polypropylene), fluororesin, etc.

[0062] A wire 40, which is an example of a linear component, and a shielding cable 30, which is an example of a linear transmission component, may have the same thickness or different thicknesses. In the case where the wire 40 and the shielding cable 30 have different thicknesses, either one may be thicker.

[0063] The structure in which a linear transmission component is held by at least one adhesive tape component can also be applied to a linear transmission component that is easily welded to a sheet component.

[0064] According to the wiring component 10 configured in this way, in a state where the bonding surface 50f faces the side of the shielded cable 30, which is an example of the linear transmission component, at least one bonding tape component 50 surrounds the shielded cable 30. Therefore, at least one bonding tape component is firmly bonded to the shielded cable 30. Since the at least one bonding tape component 50 is bonded to the sheet component 20 via the bonding surface 50f, it is easy to firmly hold the shielded cable 30 on the sheet component 20.

[0065] In addition, if the bonding tape component 50 is wound and bonded to the shielded cable 30, the bonding tape component 50 is easily and firmly bonded to the shielded cable 30.

[0066] In addition, if the bonding tape component 50 extends outward from the shielded cable 30 and is wound around the sheet component 20, the bonding tape component 50 is firmly bonded to the sheet component 20. Thereby, the shielded cable 30 is more reliably and firmly held on the sheet component 20. In particular, if a structure is formed in which the bonding tape component 50 is wound around the sheet component 20 more than once and bonded again to the bonding tape component 50 around the shielded cable 30, the shielded cable 30 is held from both sides by the bonding tape component 50. Thereby, the shielded cable 30 is more firmly held in a constant position relative to the sheet component 20.

[0067] In addition, the wiring component 10 includes a wire 40 as an example of the fused linear transmission component 40. Therefore, for the wire 40 suitable for fusion, it is fused to the sheet component 20, and for the shielded cable 30 not suitable for fusion, it can be held on the shielded cable 30 by at least one bonding tape component 50. Thereby, it is possible to mix the wire 40 suitable for fusion and the shielded cable 30 not suitable for fusion, and a thin wiring component 10 can be realized.

[0068] [Modification Example]

[0069] A modification example based on the above-described embodiment will be described. In addition, the same reference numerals are assigned to the structural elements that are the same as those described in the embodiment, and the description thereof is omitted.

[0070] Figure 3 It is a cross-sectional view showing a wiring component 110 according to a first modification example. This wiring component 110 includes at least one bonding tape component 150 corresponding to the at least one bonding tape component 50. Here, the at least one bonding tape component 150 refers to one bonding tape component 150.

[0071] The winding method of the adhesive tape member 150 around the shielded cable 30 is different from the above-described embodiment. That is, one end side portion of the adhesive tape member 150 is wound around the shielded cable 30. Here, one end side portion of the adhesive tape member 150 is wound around the shielded cable 30 for one turn. By the middle portion of the portion of the adhesive tape member 150 wound around the shielded cable 30 extending outward from a part of the circumferential direction of the shielded cable 30, a laterally extending portion 152 is formed. The laterally extending portion 152 extends from the shielded cable 30 toward one side edge portion of the sheet member 20. In the laterally extending portion 152, two portions of the adhesive tape member 150 overlap in a state where the adhesive surfaces 50f face each other. Therefore, the laterally extending portion 152 includes a portion where two portions of the adhesive tape member 150 are adhesively laminated with the adhesive surfaces 50f facing each other and a folded portion where the adhesive tape member 150 is folded at its outer end portion.

[0072] One end portion of the adhesive tape member 150 is provided as an extending end portion 154 that extends from the shielded cable 30 in a direction opposite to the above-described laterally extending portion 152. The adhesive tape member 150 is wound around the shielded cable 30 for one turn while forming the laterally extending portion 152 and is laminated on the extending end portion 154. The extending end portion 154 and the portion of the adhesive tape member 150 laminated on the extending end portion 154 are held in a laminated state by the adhesion of the adhesive surfaces 50f to each other.

[0073] The other end side portion of the adhesive tape member 150 extends outward from the extending end portion 154, passes through the main surface 22 of the shielded cable 30, the edge of the sheet member 20, the other main surface 24, the opposite edge of the sheet member 20, and one main surface 22, and reaches the shielded cable 30 again. The other end portion of the adhesive tape member 150 is adhered to the laterally extending portion 152. The other end portion of the adhesive tape member 150 may also be adhered to a portion on the outer peripheral side of the shielded cable 30 in the adhesive tape member 150 beyond the laterally extending portion 152. The other end portion of the adhesive tape member 150 may also be adhered on the portion of the adhesive tape member 150 adhered to the above-described extending end portion 154.

[0074] According to the present wiring component 110, the side extension portion 152 extends from the shielded cable 30. By disposing the side extension portion 152 along the main surface of the sheet member 20, the shielded cable 30 is stably disposed on the sheet member 20. For example, the side extension portion 152 contacts the main surface 22 or the electric wire 40 on the main surface, so that the shielded cable 30 is not easily rolled on the sheet member 20 and the position of the shielded cable 30 is stable. Further, for example, the adhesive tape member 150 reaches the side extension portion 152 and adheres to the side extension portion 152, so that the adhesive tape member 150 that wraps around the sheet member 20 adheres to the side extension portion 152 over a large area. Thus, the shielded cable 30 is stably held from both sides of the shielded cable 30 by the adhesive tape member 150, and the position of the shielded cable 30 is stable.

[0075] In addition, in the above example, the lengths of the side extension portion 152 and the extension end portion 154 are set to reach the extent between the edge of the sheet member 20 and the shielded cable 30, but the lengths are not particularly limited. For example, the side extension portion and the extension end portion may also be lengths that reach the edge of the sheet member.

[0076] Figure 4 It is a cross-sectional view showing a wiring component 210 according to a second modification. The present wiring component 210 includes at least one adhesive tape member 250, 256 corresponding to at least one adhesive tape member 50. Here, the at least one adhesive tape member 250, 256 includes a first adhesive tape member 250 and a second adhesive tape member 256.

[0077] The first adhesive tape member 250 and the second adhesive tape member 256 are strip-shaped members having an adhesive surface 50f, similar to the above-described adhesive tape member 50. The first adhesive tape member 250 is longer than the second adhesive tape member 256. The first adhesive tape member 250 is set to have a length that can be wound around the sheet member 20 more than once. The second adhesive tape member 256 is set to be equal to or less than the width of the sheet member 20.

[0078] One end side portion of the first adhesive tape member 250 overlaps the second adhesive tape member 256 along the width direction of the sheet member 20 with the adhesive surfaces 50f facing each other. The shielded cable 30 is disposed between the intermediate portion in the extending direction of the first adhesive tape member 250 and the intermediate portion in the extending direction of the second adhesive tape member 256. The adhesive surfaces 50f of the first adhesive tape member 250 and the second adhesive tape member 256 are adhered to the outside of both sides of the shielded cable 30. In the following description, sometimes a portion near one end portion of the first adhesive tape member 250 among the two overlapping portions of the first adhesive tape member 250 and the second adhesive tape member 256 is referred to as an overlapping portion 259a, and the other is referred to as an overlapping portion 259b.

[0079] In addition, between the overlapping portions 259a and 259b, the bonding surface 50f is bonded to the outer peripheral surface of the shielded cable 30. Thus, between the first bonding tape member 250 and the second bonding tape member 256, the shielded cable 30 is held in a more constant position.

[0080] The other end side portion of the first bonding tape member 250 extends from the end of the second bonding tape member 256 and is bonded to the sheet member 20. Here, the other end side portion of the first bonding tape member 250 extends outward from the second bonding tape member 256, passes through the main surface 22 of the shielded cable 30, the edge of the sheet member 20, the other main surface 24, the opposite edge of the sheet member 20, and one main surface 22 and then reaches the shielded cable 30 again. The other end portion of the first bonding tape member 250 is bonded to the overlapping portion 259a. The other end portion of the first bonding tape member 250 may also be bonded to the portion on the outer peripheral side of the shielded cable 30 in one side end portion of the first bonding tape member 250. The other end portion of the first bonding tape member 250 may also extend beyond the shielded cable 30 and be bonded to the overlapping portion 259b.

[0081] According to this wiring component 210, by arranging the overlapping portions 259a and 259b along the main surface of the sheet member 20, the shielded cable 30 is stably arranged on the sheet member 20. For example, the overlapping portions 259a and 259b contact the main surface 22 or the electric wire 40 on the main surface, so that the shielded cable 30 is not likely to roll on the sheet member 20 and the position of the shielded cable 30 is stable. In addition, for example, the first bonding tape member 250 reaches the overlapping portion 259a and is bonded to the overlapping portion 259a, so that the first bonding tape member 250 that goes around the sheet member 20 is bonded to the overlapping portion 259a with a larger area. Thus, by stably holding the shielded cable 30 from both sides of the shielded cable 30 by the first bonding tape member 250 and the second bonding tape member 256, the position of the shielded cable 30 is stable.

[0082] In addition, in the above example, the lengths of the overlapping portions 259a and 259b are set to reach the extent between the edge of the sheet member 20 and the shielded cable 30, but this length is not particularly limited. For example, the overlapping portion may also be a length that reaches the edge of the sheet member.

[0083] Figure 5FIG. 0 is a top view showing a wiring component 310 according to a third modification. In this wiring component 310, the at least one adhesive tape member 50 is provided at both end portions of the sheet member 20. The at least one adhesive tape member 50 is provided at a position where a portion of the shielded cable 30 extending from the sheet member 20 can be held on the sheet member 20. In other words, the holding structure based on the at least one adhesive tape member 50 is provided at the position closest to the extended portion in the holding structure for holding the shielded cable 30 on the sheet member 20. That is, in the holding structure based on the at least one adhesive tape member 50, the portion of the shielded cable 30 extending from the sheet member 20 is the portion that receives the force when being pulled. For example, the at least one adhesive tape member 50 may be provided at a position spaced 5 cm or less from the end portion of the sheet member 20.

[0084] Thus, the portion of the shielded cable 30 extending from the sheet member 20 is firmly held by the at least one adhesive tape member 50.

[0085] The at least one adhesive tape member 50 preferably surrounds the shielded cable 30 at a position closer to the inside than the edge of the sheet member 20. Thus, the at least one adhesive tape member 50 can hold the shielded cable 30 without protruding from the end edge of the sheet member 20 from which the shielded cable 30 extends.

[0086] In addition, in this wiring component 310, the electric wire 40 is welded to the sheet member 20 via a plurality of local welding portions 342. An auxiliary adhesive member 370 is provided which is adhered to the electric wire 40 and the sheet member 20 so as to press between the plurality of welding portions 342 in the electric wire 40.

[0087] The auxiliary adhesive member 370 may be the same member as the above-mentioned adhesive tape member. The auxiliary adhesive member 370 may be adhered to the sheet member 20, the shielded cable 30, and the electric wire 40 in a state of surrounding the sheet member 20, the shielded cable 30, and the electric wire 40.

[0088] By this auxiliary adhesive member 370, it is possible to press between the plurality of welding portions 342 in the electric wire 40 toward the sheet member 20. In addition, when there are a plurality of welding portions in the extending direction of the electric wire 40, a structure in which the electric wire 40 is pressed against the sheet member by an adhesive tape member such as the above-mentioned auxiliary adhesive member 370 between the plurality of welding portions 342 can also be established as a technique for pressing the floating of the electric wire between the welding portions without taking the adhesive tape member 50 and the shielded cable 30 as a prerequisite.

[0089] It is not necessary for the auxiliary bonding member 370 to be in a state of surrounding the shielded cable 30. At the end of the sheet member 20, when operating the connectors 60, 62, etc., a force acts to peel the shielded cable 30 from the sheet member 20. Therefore, at the end of the sheet member 20, a structure that firmly holds the shielded cable 30, such as the structure using the bonding tape member 50 described above, is preferably applied. On the other hand, at the middle part in the extending direction of the sheet member 20, the shielded cable 30 may not be held as firmly as at the end of the sheet member 20. Therefore, at the middle part in the extending direction of the sheet member 20, the auxiliary bonding member 370 may not individually surround the shielded cable 3, but may surround the sheet member 20, the shielded cable 30, and the electric wire 40. However, the auxiliary bonding member 370 may also be in a state of surrounding the shielded cable 30 as in the above-described embodiment and each modified example.

[0090] Figure 6 It is a top view showing the wiring component 410 according to the fourth modified example. As shown in this figure, the linear transmission component 430 corresponding to the linear transmission component 30 may also include a bent path portion 432 that is bent on the main surface 422 corresponding to the main surface 22. Here, the sheet member 420 is formed in a shape that is bent in an L shape.

[0091] The linear transmission component 430 is arranged on the main surface 422 along a path that is bent in an L shape in the same shape as the overall shape of the sheet member 420. The two end portions of the linear transmission component 430 extend linearly along the linear portions on both ends of the sheet member 420. The end portion of the linear transmission component 430 extends from the end of the sheet member 420 and is connected to the connectors 60, 62. The middle part in the extending direction of the linear transmission component 430 is bent at the bent portion of the sheet member 420. Here, the portion of the linear transmission component 430 extending from the bent path portion 432 is bent at an angle of 90°. The bent path portion 432 may be bent in such a way that the portion of the linear transmission component 430 extending from the bent path portion 432 is bent at an angle greater than 90° and less than 180°, or may be bent at an angle less than 90°. The bent path portion 432 may be bent in an angular shape or may be bent while curving.

[0092] The fused linear transmission component 440 corresponding to the fused linear transmission component 40 is arranged along the linear transmission component 430. The number of the fused linear transmission components 440 is arbitrary. The fused linear transmission component 440 may be omitted.

[0093] At least one bonding tape member 450 corresponding to at least one bonding tape member 50 presses the linear transmission component 430 toward the sheet member 420 at positions on both sides of the bent path portion 432.

[0094] Therefore, two portions of the linear transmission member 430 extending outward from both sides of the bent path portion 432 are held by at least one adhesive tape member 450 respectively. Thus, the linear transmission member 430 along the bent path is easily held along a constant path on the sheet member 420.

[0095] In addition, each structure described in the above embodiments and each modification can be appropriately combined as long as they do not contradict each other.
