DESCRIPTION OF EMBODIMENT(S)

Description of Embodiment of Present Disclosure

Embodiments of the present disclosure are listed and described firstly.

A wiring member-equipped adherend according to the present disclosure is as follows.

(1) A wiring member-equipped adherend includes: an adherend including an attached surface; a first sheet overlapped with the attached surface; a second sheet overlapped with the first sheet; a wire-like transmission member located between the first sheet and the second sheet; and an adhesive agent bonding the first sheet, the second sheet, and the adherend, wherein a void reaching a second surface directed to the second sheet from a first surface directed to the attached surface is formed in the first sheet, the adhesive agent includes a first layer provided between the first surface and the attached surface and a second layer penetrating the first sheet from the first layer via the void, the first surface is bonded to the attached surface via the first layer, and a part of the second surface on a lateral side of the wire-like transmission member is bonded to the second sheet via the second layer. Fixation of the first sheet and the adherend and fixation of the first sheet and the second sheet are performed by the first layer and the second layer of the adhesive agent. Accordingly, fixation of the first sheet and the second sheet sandwiching the wire-like transmission member and fixation of the first sheet and the adherend are simply performed. The first layer forms a layer between the first sheet and the adherend, thus the first sheet and the adherend can be relatively rigidly fixed to each other.

(2) In the wiring member-equipped adherend according to (1), it is applicable that the first sheet includes a non-woven cloth layer, and the void of the first sheet is formed between a plurality of fibers in the non-woven cloth layer. Accordingly, the void of the first sheet is simply provided.

(3) In the wiring member-equipped adherend according to (1) or (2), it is applicable that a void reaching an inner portion of the second sheet from a third surface directed to the first sheet in the second sheet is formed in the second sheet, and the adhesive agent includes a third layer penetrating the second sheet via the void of the second sheet. Such a configuration causes anchor effect also on a side of the second sheet in fixation of the first sheet and the second sheet, and fixation strength is increased.

(4) In the wiring member-equipped adherend according to (3), it is applicable that the second sheet includes a non-woven cloth layer, and the void of the second sheet is formed between a plurality of fibers in the non-woven cloth layer. Accordingly, the void of the second sheet is simply provided.

(5) In the wiring member-equipped adherend according to (3) or (4), it is applicable that the void of the second sheet reaches a fourth surface of the second sheet facing a side opposite to the third surface from the third surface, and the adhesive agent does not reach the fourth surface. Accordingly, suppressed is exposure of the adhesive agent to the fourth surface of the second sheet.

(6) In the wiring member-equipped adherend according to any one of (1) to (5), the wire-like transmission member may be fixed to any one of the first sheet and the second sheet. Accordingly, when the first sheet and the second sheet sandwich the wire-like transmission member, the wire-like transmission member may hardly come out from between the first sheet and the second sheet. Accordingly, a fixing operation is easily performed.

(7) In the wiring member-equipped adherend according to any one of (1) to (6), the second sheet may be shorter than the first sheet along an extension direction of the wire-like transmission member. Accordingly, weight of the wiring member-equipped adherend can be reduced compared with a case where the second sheet has the same length as the first sheet along the extension direction of the wire-like transmission member.

(8) In the wiring member-equipped adherend according to (7), the wire-like transmission member may be fixed to the first sheet. Accordingly, the wire-like transmission member can be integrated with the first sheet over a wide range, and the first sheet provided with the wire-like transmission member can be easily handled.

The wiring member-equipped adherend10includes an adherend20, a first sheet30, a second sheet40, a wire-like transmission member50, and an adhesive agent60.

The adherend20is a member provided in a position where the wire-like transmission member50is disposed in a vehicle. In the example illustrated inFIG.1, an intermediate portion of the wire-like transmission members50is disposed on the adherend20. A first end portion of the wire-like transmission member50extends to an outer side from a first end portion of the adherend20. A second end portion of the wire-like transmission member50extends to an outer side from a second end portion of the adherend20. One of or both the first end portion and the second portion of the wire-like transmission member50may be disposed on the adherend20.

The adherend20is a component provided to a vehicle. For example, the adherend20is a member provided to a vehicle later. The adherend20may be incorporated into the vehicle together with the wire-like transmission member50. The adherend20and the wire-like transmission member50may be transported to a vehicle assembly plant in a state of the wiring member-equipped adherend10. The adherend20may be a rigid member, for example. Each of the flexible first sheet30, second sheet40, and wire-like transmission member50may be fixed to the adherend20, thereby being kept in a shape corresponding to the adherend20.

The adherend20may be a bracket, for example. The adherend20may have the other function in addition to the function of fixing the wire-like transmission member50. Such a function may be a function of fixing an apparatus, for example. The adherend20may be provided with a fixing part fixed to a vehicle. When the adherend20and the vehicle are fixed by a screw, the fixing part provided to the adherend20is preferably a part used for screwing, and may be a through hole, a screw hole, a nut, or a stud bolt, for example.

The adherend20may be a member previously assembled to a vehicle before the wire-like transmission member50is assembled to the vehicle. The adherend20and the wire-like transmission member50may be transported to a vehicle assembly plant separately from each other. For example, the adherend20may be a body panel or a body frame.

The adherend20includes an attached surface22. The first sheet30is bonded to the attached surface22via the adhesive agent60. Herein, the attached surface22is made of metal. The adherend20is a member including a metal member such as a single body of a metal member or a composite member of a metal member and a resin member, for example. A surface of this metal member serves as the attached surface22. However, the attached surface22may be made of resin. In this case, the adherend20is a member including a resin member such as a single body of a resin member or a composite member of a metal member and a resin member, for example, and a surface of the resin member serves as the attached surface22.

The first sheet30is overlapped with the attached surface22. The first sheet30includes a first surface31and a second surface32. The first surface31is a surface directed to the attached surface22. The second surface32is a surface directed to the second sheet40. A void35is formed in the first sheet30. The void35reaches the second surface32from the first surface31.

The first sheet30includes a non-woven cloth layer33. The void35of the first sheet30is formed between a plurality of fibers34in the non-woven cloth layer33. In the present example, the first sheet30has a single layer structure. The first sheet30includes only the non-woven cloth layer33. The first sheet30may have a multilayer structure.

A part of the first sheet30serves as a cover part36, and the other part thereof serves as a sheet fixing part37. The cover part36is a part covering the wire-like transmission member50. The sheet fixing part37is a part fixed to the second sheet40. An intermediate portion of the first sheet30along a parallel direction of the wire-like transmission member50is the cover part36and both end portions thereof is the sheet fixing part37.

The second sheet40is overlapped with the first sheet30. The second sheet40includes a third surface41and a fourth surface42. The third surface41is a surface directed to the first sheet30. The fourth surface42is a surface directed to a side opposite to the third surface41. A void45is formed in the second sheet40. The void45reaches an inner portion of the second sheet40from the third surface41. The void45reaches the fourth surface42from the third surface41herein.

The second sheet40includes a non-woven cloth layer43. The void45of the second sheet40is formed between a plurality of fibers44in the non-woven cloth layer43. In the present example, the second sheet40has a single layer structure. The second sheet40includes only the non-woven cloth layer43. The second sheet40may have a multilayer structure.

A part of the second sheet40serves as a cover part46, and the other part thereof serves as a sheet fixing part47. The cover part46is a part covering the wire-like transmission member50from a side opposite to the cover part36. The wire-like transmission member50is disposed between the cover parts36and46. The sheet fixing part47is a part fixed to the first sheet30. The sheet fixing parts37and47are fixed by the adhesive agent60while being in contact with each other. An intermediate portion of the second sheet40along the parallel direction of the wire-like transmission member50is the cover part46and both end portions thereof is the sheet fixing part47.

The first sheet30is longer than the second sheet40along an extension direction of the wire-like transmission member50. In the example illustrated inFIG.1, the first sheet30is longer than the adherend20. The first end portion of the first sheet30extends to an outer side from the first end portion of the adherend20together with the wire-like transmission member50. The second end portion of the first sheet30extends to an outer side from the second end portion of the adherend20together with the wire-like transmission member50. One of or both the first end portion and the second portion of the first sheet30may be disposed on the adherend20.

The second sheet40is shorter than the first sheet30along the extension direction of the wire-like transmission member50. In the example illustrated inFIG.1, the second sheet40substantially has the same length as the adherend20. A dimension along the extension direction of the wire-like transmission member50is larger than that along the parallel direction of the wire-like transmission member50in the second sheet40. Both the first end portion and the second portion of the second sheet40are disposed on the adherend20. The first end portion of the second sheet40is disposed on the first end portion of the adherend20, and the second end portion of the second sheet40is disposed on the second end portion of the adherend20. One of or both the first end portion and the second portion of the second sheet40may extend to an outer side from the end portion of the adherend20.

The second sheet40may be formed to have a small length along the extension direction of the wire-like transmission member50to be provided in a plurality of positions at intervals on the adherend20. A dimension along the extension direction of the wire-like transmission member50may be smaller than that along the parallel direction of the wire-like transmission member50in the second sheet40, for example.

The fibers34and44in the non-woven cloth layers33and43may be a synthesized fiber or a natural fiber. The synthesized fiber may be made of resin. A type of the resin is not particularly limited, but polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyethylene (PE), or polypropylene (PP), can be adopted, for example. A non-woven cloth of the non-woven cloth layer33and a non-woven cloth of the non-woven cloth layer43may be the same type or different types of cloth. A material, a thickness, or a weight per area, for example, may be different as two different types of non-woven cloth.

The wire-like transmission member50is a wire-like member transmitting electricity or light, for example. One or a plurality of wire-like transmission members50are provided. The wire-like transmission member50is assumed to be a member connecting components in a vehicle. A connector, for example, is provided to an end portion of the wire-like transmission member50. This connector is connected to a connector provided to the other side component, thus the wire-like transmission member50is connected to the other side component. The connector may be fixed to the first sheet30. The connector may be provided to an outer side of the first sheet30.

The wire-like transmission member50includes a transmission wire body51and a covering layer52. The transmission wire body51is a transmission route transmitting electricity or light. For example, when the wire-like transmission member50is an electrical wire, the transmission wire body51is a conductor core wire. The conductor core wire is made up of one or a plurality of strands. The strand is formed of copper, copper alloy, aluminum, or aluminum alloy as a material, for example. For example, when the wire-like transmission member50is an optical fiber, the transmission wire body51is a core and a clad. The covering layer52is a layer covering the transmission wire body51. A resin material constituting the covering layer52is not particularly limited, but can be appropriately set. For example, the wire-like transmission member50may be a general wire having a core wire and a covering layer52around the core wire, or may also be a shield wire, a twisted wire, an enamel wire, a nichrome wire, or an optical fiber.

The wire-like transmission member50transmitting the electricity may be various kinds of signal lines or various kinds of power lines. Some of the wire-like transmission members50transmitting the electricity may be used as an antenna or coil, for example, transmitting or receiving a signal or electrical power to or from a space.

The wire-like transmission member50may be a single core wire. The single core wire is a single wire-like object. The single core wire is the wire-like transmission member50with one transmission route. The wire-like transmission member50may be a multicore wire. The multicore wire is a compound body of a plurality of wire-like objects. The multicore wire is the wire-like transmission member50with a plurality of transmission routes. The multicore wire may be a cable made up of collected twisted wires or a plurality of wire-like objects covered by a sheath, for example.

The wire-like transmission member50is located between the first sheet30and the second sheet40. The wire-like transmission member50is fixed to any one of the first sheet30and the second sheet40. In the present example, the wire-like transmission member50is fixed to the first sheet30. In the description hereinafter, the first sheet30and the wire-like transmission member50integrated with each other are referred to as a wiring body100. The wiring body100is used as a wiring member electrically connecting various types of component in a vehicle, for example (or connecting them so that they can perform optical communication).

The first sheet30and the wire-like transmission member50are partially fixed to each other along the extension direction of the wire-like transmission member50. The fixing part thereof is referred to as a spot fixing part102. The plurality of spot fixing parts102are provided at intervals along the extension direction of the wire-like transmission member50. The interval between the spot fixing parts102is not particularly limited, but can be appropriately set. However, the fixing part between the first sheet30and the wire-like transmission member50needs not be the spot fixing part102. The fixing part between the first sheet30and the wire-like transmission member50may be continuously provided to have a large length along the extension direction of the wire-like transmission member50.

Any fixing state may be applied as a fixing state in the spot fixing part102between the first sheet30and the wire-like transmission member50. Applicable as the fixing state are a contact area fixation and a non-contact area fixation, or both fixations may be used together. Herein, the contact area fixation indicates that a portion where the first sheet30and the wire-like transmission member50have contact with each other is stuck and fixed. The non-contact area fixation is a fixing state which is not the contact area fixation, and indicates that a sewing thread, a cover, or an adhesive tape presses the wire-like transmission member50toward the first sheet30or sandwiches the first sheet30and the wire-like transmission member50to keep them in a fixing state. In the description hereinafter, the first sheet30and the wire-like transmission member50are in the state of the contact area fixation.

Applicable as the configuration of the contact area fixation are a contact area indirect fixation and a contact area direct fixation, or both fixations may also be used together in different regions. Herein, the contact area indirect fixation indicates that the first sheet30and the wire-like transmission member50are indirectly stuck and fixed via an adhesive member such as an adhesive agent, a gluing agent, and a double-sided adhesive tape provided therebetween. The contact area direct fixation indicates that the first sheet30and the wire-like transmission member50are directly stuck and fixed without an intervention of the adhesive agent, for example, which is separately provided. Considered in the contact area direct fixation is that resin included in at least one of the first sheet30and/or the wire-like transmission member50is melted, thus the first sheet30and the wire-like transmission member50are stuck and fixed, for example.

In forming the state of such a contact area direct fixation, the resin is considered to be melted by heat or a solvent, for example. That is to say, the state of the contact area direct fixation may be the state of the contact area direct fixation by the heat or the state of the contact area direct fixation by the solvent. The contact area direct fixation by the heat is preferable.

At this time, a means of forming the state of the contact area direct fixation is not particularly limited, but a known means such as welding, fusion, and melting joint can be used. Herein, in the spot fixing part102between the first sheet30and the wire-like transmission member50, the first sheet30and the wire-like transmission member50are fused to each other. In the present example, the non-woven cloth layer33of the first sheet30and an outermost layer of the wire-like transmission member50are fused to each other. The outermost layer of the wire-like transmission member50is the covering layer52.

A route of the wire-like transmission member50is set in accordance with a position of a component to which the wire-like transmission member50is connected, for example. The wire-like transmission members50are fixed to the first sheet30, thus the wire-like transmission members50are kept in a form following a wiring route corresponding to a position of a component as a connection destination of each wire-like transmission member50. Herein, the wire-like transmission members50extend straight on the first sheet30. The first sheet30is formed into a shape in accordance with a route of the wire-like transmission member50(straight shape, herein). However, the route of the wire-like transmission members50may be made up of a combination of a straight route and a bending route. The first sheet30may also be made up of a combination of a straight route and a bending route. The plurality of wire-like transmission members50may be fixed to the first sheet30in a state where a branch wire is branched from a main wire. The first sheet30may also be formed into a shape in which a part to which the branch wire is fixed is branched from a part to which the main wire is fixed.

The first sheet30and the second sheet40may be flexible members. For example, the first sheet30and the second sheet40are non-woven clothes having flexibility, and are flexible members. For example, the first sheet30may have flexibility so as to be able to follow bending of the wire-like transmission member50. It is also applicable that the first sheet30and the wire-like transmission member50can be bended in a thickness direction (bending so that a fold line follows a main surface of the first sheet30).

The adhesive agent60bonds the adherend20, the first sheet30, and the second sheet40. The adhesive agent60includes a first layer61and a second layer62. The adhesive agent60further includes a third layer63. The first layer61is provided between the first surface31and the attached surface22. The second layer62penetrates the first sheet30from the first layer61via the void35. The third layer63penetrates the second sheet40from the second layer62via the void45. The adhesive agent60penetrating an inner portion of the second sheet40does not reach the fourth surface42.

The first surface31is bonded to the attached surface22via the first layer61. The first surface31does not have contact with the attached surface22in the sheet fixing part37of the first sheet30. The first surface31is located away from the attached surface22by a thickness of the first layer61in the sheet fixing part37of the first sheet30. The adhesive agent60is not provided to a portion of the cover part36herein. The first surface31has contact with the attached surface22in the cover part36of the first sheet30. The adhesive agent60may also be provided to a portion of the cover part36.

A part of the second surface32on a lateral side of the wire-like transmission member50is bonded to the second sheet40via the second layer62. The second surface32is bonded to the second sheet40via the second layer62in the sheet fixing part37of the first sheet30. At this time, the third layer63penetrating the second sheet40is located, thus fixation strength between the second sheet40and the adhesive agent60is increased.

The second surface32and the third surface41have contact with each other in a part except for the voids35and45. The second surface32and the third surface41are bonded to each other via the second layer62and the third layer63penetrating the voids35and45.

Some fibers34of the first sheet30and some fibers44of the second sheet40have contact with each other. The adhesive agent60of the second layer62and the third layer63covers around the fibers34and44having contact with each other.

A type of the adhesive agent60is not particularly limited, however, any type is applicable as long as the adhesive agent60is heated and softened to be able to have flowability. The adhesive agent60may be a hot-melt adhesive agent, for example.

A thickness of the first layer61is not particularly limited, but can be appropriately set. For example, the thickness of the first layer61may be the same as that of the sheet fixing part37of the first sheet30, or may also be larger or smaller than that thereof. For example, the thickness of the first layer61may be 0.1 mm to 2 mm.

The second layer62penetrates the second surface32from the first surface31in the sheet fixing part37. The second layer62penetrates the whole first sheet30in a thickness direction in the sheet fixing part37. Thus, the thickness of the second layer62is the same as that of the sheet fixing part37of the first sheet30. The thickness of the sheet fixing part37of the first sheet30may be the same as or different from that of the cover part36. A non-woven cloth having a uniform thickness may be used as the non-woven cloth layer33of the first sheet30. It is also applicable that this non-woven cloth is compressed when being bonded and fixed to the adherend20and the second sheet40, and the sheet fixing part37has a smaller thickness than the cover part36.

The third layer63does not penetrate the fourth surface42from the third surface41in the sheet fixing part47. The third layer63penetrates a part of the sheet fixing part47along the thickness direction of the second sheet40. Thus, the thickness of the third layer63is smaller than that of the sheet fixing part47of the second sheet40. The thickness of the third layer63may be equal to or larger than1/4and equal to or smaller than3/4of the thickness of the sheet fixing part47of the second sheet40, for example.

In the example illustrated inFIG.1, the adhesive agent60is partially provided along the extension direction of the wire-like transmission member50. The adhesive agent60is provided in a plurality of positions at intervals along the extension direction of the wire-like transmission member50. The adhesive agent60is provided to the first end portion and the second end portion of the adherend20. The adhesive agent60is not provided between the first end portion and the second end portion of the adherend20. The adhesive agent60may be provided between the first end portion and the second end portion of the adherend20. The adhesive agent60may be continuously provided between the first end portion and the second end portion of the adherend20.

A method of manufacturing the wiring member-equipped adherend10is described next.

As illustrated inFIG.4, a sheet-like hot-melt adhesive agent (referred to as an adhesive agent sheet60B hereinafter) before being heated is provided on the attached surface22. The first sheet30and the second sheet40are provided on the adhesive agent sheet60B. The wire-like transmission member50is provided between the first sheet30and the second sheet40. In the example illustrated inFIG.4, the first sheet30and the wire-like transmission member50are integrally provided to be the wiring body100. A bonded part is pressed by press members80and81while the first sheet30and the second sheet40are overlapped with each other so that the second surface32and the third surface41have contact with each other, and the adhesive agent sheet60B is heated. At this time, one of or both the press members80and81may double as a heating member. The heating member may be provided separately from the press members80and81. A method of heating the adhesive agent sheet60B is not particularly limited, but can be appropriately set.

When the adhesive agent sheet60B is heated, the adhesive agent is softened over time and has flowability. The adhesive agent having flowability penetrates an inner portion of the first sheet30from the first surface31via the void35to reach the second surface32. Furthermore, the adhesive agent having flowability penetrates an inner portion of the second sheet40from the third surface41having contact with the second surface32via the void45. At this time, the adhesive agent has stickiness so as to be able to pass through the first sheet30while having flowability and further penetrate the inner portion of the second sheet40. The adhesive agent has stickiness so as to be able to be left between the attached surface22and the first surface31while having flowability.

The wiring member-equipped adherend10described above is completed while the adhesive agent penetrating the inner portion of the second sheet40does not reach the fourth surface42. For example, the adhesive agent penetrating the inner portion of the second sheet40can be prevented from reaching the fourth surface42by adjusting a heating time or pressure of the press member.

According to the wiring member-equipped adherend10having the above configuration, fixation of the first sheet30and the adherend20and fixation of the first sheet30and the second sheet40are performed by the first layer61and the second layer62of the adhesive agent60. Accordingly, fixation of the first sheet30and the second sheet40sandwiching the wire-like transmission member50and fixation of the first sheet30and the adherend20are simply performed. The first layer61forms the layer between the first sheet30and the adherend20, thus the first sheet30and the adherend20can be relatively rigidly fixed to each other. The second layer62is the layer penetrating the first sheet30, thus the adhesive agent60is rigidly fixed to the first sheet30by anchor effect.

For example, the second layer62can be formed by the adhesive agent sheet60B between the first sheet30and the adherend20softened and penetrating the first sheet30. Accordingly, fixation of the first sheet30and the adherend20and fixation of the first sheet30and the second sheet40can be performed by one fixing operation.

The first sheet30includes the non-woven cloth layer33, and the void35of the first sheet30is formed between the plurality of fibers34in the non-woven cloth layer33. Accordingly, the void35of the first sheet30is simply provided.

The void45reaching the inner portion of the second sheet40from the third surface41of the second sheet40directed to the first sheet30is formed in the second sheet40, and the adhesive agent60includes the third layer63penetrating the second sheet40via the void45of the second sheet40. Such a configuration causes anchor effect also on the second sheet40in fixation of the first sheet30and the second sheet40via the adhesive agent60, and fixation strength is increased.

The second sheet40includes the non-woven cloth layer43, and the void45of the second sheet40is formed between the plurality of fibers44in the non-woven cloth layer43. Accordingly, the void45of the second sheet40is simply provided.

The void45of the second sheet40reaches the fourth surface42of the second sheet40directed to the side opposite to the third surface41from the third surface41, and the adhesive agent60does not reach the fourth surface42. Accordingly, suppressed is exposure of the adhesive agent60to the fourth surface42of the second sheet40. Adhesion of the adhesive agent60to the press member81is suppressed.

The wire-like transmission member50is fixed to any one of the first sheet30and the second sheet40. Accordingly, when the first sheet30and the second sheet40sandwich the wire-like transmission member50, the wire-like transmission member50hardly comes out from between the first sheet30and the second sheet40. Accordingly, a fixing operation is easily performed.

The second sheet40is shorter than the first sheet30along the extension direction of the wire-like transmission member50. Accordingly, weight of the wiring member-equipped adherend10can be reduced compared with the case where the second sheet40has the same length as the first sheet30along the extension direction of the wire-like transmission member50. At this time, the wire-like transmission member50is fixed to the first sheet30. Accordingly, the wire-like transmission member50can be integrated with the first sheet30over a wide range, and the first sheet30provided with the wire-like transmission member50can be easily handled.

Appendix

FIG.6is a cross-sectional view illustrating a modification example of the wiring member-equipped adherend10. A wiring member-equipped adherend110illustrated inFIG.6is different from the wiring member-equipped adherend10described above in that a first sheet130has a multilayer structure. The first sheet130has a double layer structure of the non-woven cloth layer33and a fusion layer38.

The fusion layer38is stacked closer to the wire-like transmission member50in relation to the non-woven cloth layer33. The fusion layer38and the wire-like transmission member50are fused and fixed to each other. The fusion layer38is the layer more suitable for fixation to the wire-like transmission member50than the non-woven cloth layer33. Accordingly, fixation strength of the spot fixing part102is increased, and the spot fixing part102hardly comes out from a wire-like transmission member150even having a large thickness, for example. The fusion layer38includes a resin material, or preferably includes a thermoplastic resin material. The resin material of the fusion layer38is softened and fused to a fusion target. The resin material is not particularly limited, however, the above resin material described for the material of the non-woven cloth layer33can be used, for example. It is preferable that a material of the covering layer52and a material of the fusion layer38have compatibility. Herein, a resin material constituting the covering layer52and a resin material constituting the fusion layer38are the same type of material. A resin material constituting the fusion layer38and a resin material constituting the covering layer52are PVC or polyolefin, for example.

The fusion layer38is a non-fibrous material sheet. The non-fibrous material sheet is a sheet which does not have a fiber. The fusion layer38may be a sheet having an evenly filled cross-sectional surface (also referred to as a non-foam sheet or a solid sheet, for example). The fusion layer38may also be a foam sheet, for example.

The fusion layer38is partially stacked to the non-woven cloth layer33. The fusion layer38is provided to the cover part36, and is not provided to the sheet fixing part37in the first sheet130. A surface of the fusion layer38constitutes the second surface32in the cover part36. A surface of the non-woven cloth layer33constitutes the second surface32in the sheet fixing part37. Accordingly, the void35can reach the second surface32also in the first sheet30having the multilayer structure of the non-woven cloth layer33and the fusion layer38. Accordingly, fixation of the first sheet130and the adherend20via the adhesive agent60and fixation of the first sheet130and the second sheet40can be performed also in the wiring member-equipped adherend110in the manner similar to the wiring member-equipped adherend10.

The fusion layer38and the non-woven cloth layer33are fixed to each other while the surface of the fusion layer38and the surface of the non-woven cloth layer33have contact with each other. A fixing state of the fusion layer38and the non-woven cloth layer33is not particularly limited, however, fixing by fusion or adhesion is preferable. The non-woven cloth layer33includes the void35, thus the resin material or the adhesive agent of the fusion layer38can enter the void35and can be fixed thereto. Such a configuration causes so-called anchor effect, thus the fusion layer38and the non-woven cloth layer33are rigidly fixed. In the description herein, the fusion layer38and the non-woven cloth layer33are fused to each other. That is to say, the resin of the fusion layer38enters between the fibers34of the non-woven cloth layer33while having flowability, and is then hardened. Accordingly, a state where the resin of the fusion layer38enters between the fibers34of the non-woven cloth layer33is maintained, and the fusion layer38and the non-woven cloth layer33are rigidly fixed.

Moreover, in the above description, the first sheet30includes the non-woven cloth layer33, and the void35of the first sheet30is formed between the plurality of fibers34in the non-woven cloth layer33, however, this configuration is not necessary. For example, the first sheet may be a fibrous material sheet different from a non-woven cloth such as a woven fabric or a braided fabric. In this case, a space between threads constituting the woven fabric or the braided fabric serves as a void of the first sheet. For example, the first sheet may be a continuous foam resin sheet. In this case, continuous foams in the continuous foam resin sheet serve as a void of the first sheet.

In the above description, the void45reaching the inner portion of the second sheet40from the third surface41of the second sheet40directed to the first sheet30is formed in the second sheet40, and the adhesive agent60includes the third layer63penetrating the second sheet40via the void45of the second sheet40, however, this configuration is not necessary. For example, the second sheet40may be a solid sheet without the void45. The void45of the second sheet40may be formed only in a position where the adhesive agent60is not located.

Moreover, in the above description, the second sheet40is the non-woven cloth layer43, and the void45of the second sheet40is formed between the plurality of fibers44in the non-woven cloth layer43, however, this configuration is not necessary. For example, the second sheet may be a fibrous material sheet different from a non-woven cloth such as a woven fabric or a braided fabric. In this case, a space between threads constituting the woven fabric or the braided fabric serves as a void of the second sheet. For example, the second sheet may be a foam resin sheet. In this case, foams in the foam resin sheet serve as a void of the second sheet. The foam resin sheet may be a continuous foam resin sheet or a closed foam resin sheet. In the case of the continuous foam resin sheet, the foam as the void reaches the fourth surface from the third surface. In the case of the closed foam resin sheet, a part of the closed foam serves as a void opened on a side of the third surface in the second sheet, and the adhesive agent from the second layer can enter the void, however, the adhesive agent cannot physically reach the fourth surface by reason that the void does not reach the fourth surface.

In the above description, the void45of the second sheet40reaches the fourth surface42of the second sheet40directed to the side opposite to the third surface41from the third surface41, and the adhesive agent60does not reach the fourth surface42, however, this configuration is not necessary. For example, the adhesive agent60may reach the fourth surface42of the second sheet40. For example, the void of the second sheet may not reach the fourth surface from the third surface. The closed foam resin sheet can be used as the second sheet in this case.

In the above description, the wire-like transmission member50is fixed to any one of the first sheet30and the second sheet40, however, this configuration is not necessary. The wire-like transmission member50may not be fixed to any one of the first sheet30and the second sheet40. In this case, a process of fixing the first sheet30or the second sheet40to the wire-like transmission member50can be omitted.

In the above description, the second sheet40is shorter than the first sheet30along the extension direction of the wire-like transmission member50, however, this configuration is not necessary. For example, the second sheet40may have the same size as the first sheet30. In the above description, at this time, the wire-like transmission member50is fixed to the first sheet30, however, this configuration is not necessary. For example, the wire-like transmission member50may be fixed to the second sheet40.

The configurations described in the embodiments and modification examples thereof can be appropriately combined as long as they are not contradictory.
