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: a wiring member including a sheet and a wire-like transmission member bonded to the sheet; and an adherend provided in a position where the wiring member is disposed in a vehicle to be bonded to the sheet, wherein a bonding part where the sheet and the adherend are bonded includes a lateral bonding part provided in a position deviated from the wire-like transmission member along a width direction of the sheet. The lateral bonding part is not overlapped with the wire-like transmission member, thus a heating amount and a pressurizing amount can be increased in forming the lateral bonding part. Accordingly, the sheet and the adherend can be firmly fixed to each other in the lateral bonding part, thus the sheet in the wiring member and the adherend are appropriately bonded with at least heating and pressurizing.(2) In the wiring member-equipped adherend according to (1), a non-bonding part where the sheet and the adherend are not bonded may be provided in a portion overlapped with the wire-like transmission member adjacent to the bonding part along the width direction of the sheet. Accordingly, a whole portion along the width direction of the sheet is not bonded to the adherend.(3) It is applicable that in the wiring member-equipped adherend according to (2), a press trace is formed in a surface of the sheet in the lateral bonding part, and a boundary between the bonding part and the non-bonding part is located closer to a side of the non-bonding part in relation to an edge of the press trace along the width direction of the sheet. It is confirmed that the boundary between the bonding part and the non-bonding part is located closer to the side of the non-bonding part in relation to the edge of the press trace, thus it is easily confirmed that the sheet and the adherend are firmly bonded in the lateral bonding part.(4) In the wiring member-equipped adherend according to (2) or (3), the bonding part may include an overlapping bonding part provided adjacent to the lateral bonding part and partially overlapped with the wire-like transmission member. The overlapping bonding part is confirmed, thus it is easily confirmed that the sheet and the adherend are firmly bonded in the bonding part.(5) It is applicable that in the wiring member-equipped adherend according to any one of (1) to (4), a plurality of spot bonding parts where the sheet and the wire-like transmission member are partially bonded along an extension direction of the wire-like transmission member are provided along the extension direction of the wire-like transmission member, and the bonding part is provided between the plurality of spot bonding parts along the extension direction of the wire-like transmission member. A distance from the bonding part to the spot bonding part is increased, thus heat and pressure in forming the bonding part are hardly transmitted to the spot bonding part.(6) It is applicable that in the wiring member-equipped adherend according to any one of (1) to (5), the bonding part includes a hot-melt adhesive agent intervening between the sheet and the adherend, and a metal attached surface in the adherend has contact with the hot-melt adhesive agent. Accordingly, the metal attached surface is heated by induction heating, and the hot-melt adhesive agent can be heated by heat transmitted from the attached surface. Accordingly, heat in forming the bonding part is hardly transmitted to the wire-like transmission member.

Detailed Description of Embodiment of Present Disclosure

Specific examples of a wiring member-equipped adherend according to the present disclosure are described hereinafter with reference to the drawings. The present disclosure is not limited to these examples, but is indicated by claims, and it is intended that meanings equivalent to claims and all modifications within a scope of claims are included.

A wiring member-equipped adherend according to an embodiment 1 is described hereinafter.FIG.1is a plan view illustrating a wiring member-equipped adherend10according to the embodiment 1.FIG.2is a cross-sectional view along a II-II line inFIG.1.

The wiring member-equipped adherend10includes a wiring member20and an adherend40. The wiring member20is bonded to the adherend40.

The wiring member20includes a sheet22and a wire-like transmission member26. The wire-like transmission member26is bonded to the sheet22. The plurality of wire-like transmission members26are arranged on a first surface of the sheet22. Each of the plurality of wire-like transmission members26is bonded to the sheet22. The plurality of wire-like transmission members26are arranged side by side on the first surface of the sheet22. Accordingly, the wiring member20is flattened by reducing a dimension in a height direction in relation to dimensions in a width direction and a length direction.

It is sufficient that the sheet22can fix the wire-like transmission member26, thus a material and a structure, for example, are not particularly limited. With regard to a material constituting the sheet22, the sheet22is formed of a resin material herein. A material other than resin such as metal or an inorganic material, for example, may be used for the material constituting the sheet22. With regard to the structure of the sheet22, the sheet22has a double layer structure herein. The structure of the sheet22may be a single layer structure, or a multilayer structure of three or more layers is also applicable.

The sheet22includes a first layer23and a second layer24. The first layer23is the fusion layer23. The wire-like transmission member26is fused and fixed to the fusion layer23. The fusion layer23includes a resin material, or preferably includes a thermoplastic resin material. The resin material of the fusion layer23is softened and fused to a fusion target. A type of the resin material is not particularly limited, but polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), or polyethylene terephthalate (PET) can be adopted, for example.

A structure of the fusion layer23is not particularly limited. For example, the fusion layer23may 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 layer23is also considered a foam sheet, for example. The fusion layer23is also considered a fibrous material sheet such as a braided cloth, a woven cloth, or a non-woven cloth, for example. One surface of the first layer23is the first surface of the sheet22.

The second layer24is formed of a material different from that of the fusion layer23, or has a different structure. The second layer24increases a function of the fusion layer23, or adds a function which the fusion layer23does not have to the sheet22. A material constituting the second layer24is a material described for the fusion layer23described above, metal, or an inorganic material, for example. A structure of the second layer24may be any of the structure described for the fusion layer23described above. One surface of the second layer24is a second surface of the sheet22.

The first layer23and the second layer24are fixed to each other while the other surface of the first layer23and the other surface of the second layer24have contact with each other. A fixing state of the first layer23and the second layer24is not particularly limited, however, fixing by fusion or adhesion is preferable. For example, when at least one of the first layer23and the second layer24is a sheet having voids in a surface such as a fibrous material sheet or a foam sheet, a resin material or an adhesive agent enters the voids and the layers can be fixed to each other. Such a configuration causes so-called anchor effect, thus the first layer23and the second layer24are rigidly fixed.

In the description herein, the first layer23is a solid sheet made of resin and the second layer24is a fibrous material sheet. In the description herein, the first layer23and the second layer24are fused to each other. That is to say, the resin of the first layer23enters between the fibers of the second layer24while having flowability, and is then hardened. Maintained accordingly is a state where the resin of the first layer23enters between the fibers of the second layer24, and the first layer23and the second layer24are rigidly fixed to each other.

The first layer23and the second layer24are formed to have the same size (the same planar shape). One of the first layer23and the second layer24may also be formed to be larger than the other one thereof. The first layer23and the second layer24are wholly fixed at a region where they have contact with each other. The first layer23and the second layer24may also be fixed only at a part of a region where they have contact with each other.

The sheet22may be a flexible member. For example, the first layer23is a solid sheet made up of flexible resin such as flexible PVC as a material, the second layer24is a non-woven cloth made up of PET as a material, and the sheet22is a flexible member. For example, the sheet22may have a plastic property so as to be able to follow bending of the wire-like transmission member26. It is also applicable that the wiring member20can be bended in a thickness direction (bending so that a fold line follows the main surface of the sheet22).

The wire-like transmission member26is a wire-like member transmitting electrical power or light, for example. One or a plurality of wire-like transmission members26are provided. The wire-like transmission member26is assumed to be a member connecting components in a vehicle. A connector, for example, is provided on an end portion of the wire-like transmission member26. This connector is connected to a connector provided in the other side component, thus the wire-like transmission member26is connected to the other side component. That is to say, the wiring member20is used as the wiring member20electrically connecting various types of component in a vehicle, for example (or connecting them so that they can perform optical communication). The connector may be fixed to the sheet22.

A route of the wire-like transmission members26is set in accordance with a position of a component to which the wire-like transmission member26is connected, for example. The wire-like transmission members26are fixed to the sheet22, thus the wire-like transmission members26are kept in a form following a wiring route corresponding to a position of a component as a connection destination of each wire-like transmission member26. Herein, the wire-like transmission members26extend straight on the sheet22. The sheet22is formed into a shape in accordance with a route of the wire-like transmission member26(straight shape, herein). However, the route of the wire-like transmission members26may be made up of a combination of a straight route and a bending route. The sheet22may also be made up of a combination of a straight route and a bending route. The plurality of wire-like transmission members26may be fixed to the sheet22in a state where a branch wire is branched from a main wire. The sheet22may also be formed into a shape in which a portion to which the branch wire is fixed is branched from a portion to which the main wire is fixed.

The wire-like transmission member26includes a transmission wire body27and a covering layer28. The transmission wire body27is a transmission route transmitting electrical power or light. For example, when the wire-like transmission member26is an electrical wire, the transmission wire body27is 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 member26is an optical fiber, the transmission wire body27is a core and a clad. The covering layer28is a layer covering the transmission wire body27. A resin material constituting the covering layer28is not particularly limited, but can be appropriately set. For example, the wire-like transmission member26may be a general wire having a core wire and a covering layer around 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 member26transmitting the electrical power may be various kinds of signal lines or various kinds of power lines. Some of the wire-like transmission members26transmitting the electrical power 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 member26may be a single core wire. The single core wire is a single wire-like object. The single core wire is the wire-like transmission member with one transmission route. The wire-like transmission member26may 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 member26with 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 sheet22and the wire-like transmission member26are fixed to each other via a spot bonding part30partially bonded along an extension direction of the wire-like transmission member26. The plurality of spot bonding parts30are provided at intervals along the extension direction of the wire-like transmission member26. The interval between the spot bonding parts30is not particularly limited, but can be appropriately set. However, the bonding part30between the sheet22and the wire-like transmission member26needs not be the spot bonding part30. The bonding part30between the sheet22and the wire-like transmission member26may be continuously provided to have a large length along the extension direction of the wire-like transmission member26.

Any fixing state may be applied as a fixing state in the bonding part30between the sheet22and the wire-like transmission member26. 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 sheet22and the wire-like transmission member26have 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 member26toward the sheet22or sandwiches the sheet22and the wire-like transmission member26to keep them in a fixing state. Tn the description hereinafter, the sheet22and the wire-like transmission member26are 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 sheet22and the wire-like transmission member26are 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 sheet22and the wire-like transmission member26are 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 sheet22and the wire-like transmission member26is melted, thus the sheet22and the wire-like transmission member26are 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 bonding part30between the sheet22and the wire-like transmission member26, the sheet22and the wire-like transmission member26are fused to each other. In this case, the fusion layer23of the sheet22and an outermost layer of the wire-like transmission member26are fused to each other. The outermost layer of the wire-like transmission member26is the covering layer28. It is sufficient that a material of the covering layer28and a material of the fusion layer23have compatibility. Herein, a resin material constituting the covering layer28and a resin material constituting the fusion layer23are the same type of material. A resin material constituting the fusion layer23and a resin material constituting the covering layer28are PVC or polyolefin, for example.

The adherend40is provided in a position where the wiring member20is disposed in a vehicle. A first end portion of the wiring member20extends to an outer side from a first end portion of the adherend40. A second end portion of the wiring member20extends to an outer side from a second end portion of the adherend40. One of or both the first end portion and the second portion of the wiring member20may be disposed on the adherend40. The adherend40is bonded to the sheet22. The second surface of the sheet22is bonded to an attached surface42of the adherend40. Herein, the attached surface42is made of metal. The adherend40is 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 surface42. However, the attached surface42may be made of resin. In this case, the adherend40is 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.

The adherend40may be a member previously assembled to a vehicle before the wiring member20is assembled to the vehicle. The adherend40and the wiring member20may be transported to a vehicle assembly plant separately from each other. For example, the adherend40may be a body panel or a body frame.

The adherend40may be a vehicle-mounted component and a member assembled to a vehicle together with the wiring member20. The adherend40and the wiring member20may be transported to a vehicle assembly plant in a state of the wiring member-equipped adherend10. The adherend40may be a bracket, for example.

It is sufficient that a fixing state of a bonding part50between the sheet22and the adherend40is accompanied with at least one of heating and pressurizing, and applicable are various types of fixing state described in the fixing state of the bonding part30between the sheet22and the wire-like transmission member26. In the description of the present example, the fixing state of the bonding part50is the contact area indirect fixation. In the description, an adhesive member at this time is a hot-melt adhesive agent. In the description, the fixing state of the bonding part50is accompanied with both heating and pressurizing. Accordingly, the bonding part50between the sheet22and the adherend40herein includes a hot-melt adhesive agent intervening between the sheet22and the adherend40. The metal attached surface42of the adherend40has contact with the hot-melt adhesive agent. The second surface of the sheet22has contact with the hot-melt adhesive agent. Herein, the second surface of the sheet22is a surface of a non-woven cloth layer. Thus, there may also be a case where a part of the hot-melt adhesive agent seeps into the non-woven cloth layer. In this case, bonding strength between the hot-melt adhesive agent and the sheet22is increased.

The bonding part50can be formed using an induction heating apparatus80and a press member82as illustrated inFIG.2, for example. When high-frequency waves flow in a coil provided to the induction heating apparatus80, current (eddy current) occurs in a metal member having the attached surface42due to change of magnetic force. The metal member having the attached surface42is heated by Joule heat due to the eddy current. The hot-melt adhesive agent having contact with the attached surface42is heated by thermal transmission from the attached surface42and softened, and is then bonded to the attached surface42of the adherend40and the second surface of the sheet22. At this time, the first surface of the sheet22is pressed by the press member82, thus bonding strength of the bonding part50is increased. Accordingly, the bonding part50is formed. The hot-melt adhesive agent may be previously bonded to one of the attached surface42of the adherend40and the second surface of the sheet22before forming the bonding part50.

When the bonding part50is observed along the width direction of the sheet22, the bonding part50includes a lateral bonding part52. The lateral bonding part52is a part of the bonding part50provided in a position deviating from the wire-like transmission member26along the width direction of the sheet22. Furthermore, the bonding part may include an overlapping bonding part53(refer toFIG.4). The overlapping bonding part53is a part of the bonding part provided in a position overlapping with the wire-like transmission member26along the width direction of the sheet22. When the wire-like transmission members26are disposed to be slightly separated from each other as illustrated inFIG.2, a part provided in a position overlapped with a part between the wire-like transmission members26may also be deemed to be the overlapping bonding part.

In the present example, the bonding part50includes only the lateral bonding part52in the lateral bonding part52and the overlapping bonding part53, and does not include the overlapping bonding part53. An example that the bonding part includes the overlapping bonding part53is described in an example in an embodiment 2 described hereinafter.

Herein, the wire-like transmission member26is disposed in an intermediate portion of the sheet22along the width direction. The lateral bonding part52is provided in both end portions of the sheet22along the width direction. However, it is also applicable that the wire-like transmission member26is disposed in both end portion of the sheet22along the width direction, and the lateral bonding part52is provided in the intermediate portion of the sheet22along the width direction. It is also applicable that the wire-like transmission member26is disposed in one end portion of the sheet22along the width direction, and the lateral bonding part52is provided in the other end portion of the sheet22along the width direction.

A non-bonding part60is provided to the wiring member-equipped adherend10. The non-bonding part60is a part where the sheet22and the adherend40are not bonded to each other. The non-bonding part60is provided in a portion overlapped with the wire-like transmission member26adjacent to the bonding part50along the width direction of the sheet22. Herein, the bonding part50has a thickness of the hot-melt adhesive agent, thus the sheet22and the wire-like transmission member26are separated from each other in the non-bonding part60. A member other than the wiring member20and the adherend40is not disposed to the non-bonding part60. Accordingly, an air layer can be deemed to be disposed in the non-bonding part60.

In the non-bonding part60, the sheet22may be warped toward the adherend40by a weight of the sheet22itself and a weight of the wire-like transmission member26, thereby reducing the air layer. As a dimension of the non-bonding part60along the width direction of the sheet increases, the sheet22is warped more easily. In the similar manner, as rigidity of the sheet22decreases, the sheet22is warped more easily. The non-bonding part60may include a part where the warped sheet22has contact with the adherend40. The warped sheet22may not have contact with the adherend40in the non-bonding part60.

A press trace25is formed in the surface of the sheet22in the lateral bonding part52. The press trace25has a concaved shape in which the surface of the sheet22is partially concaved. The press trace25is a trace formed by pressing the surface of the sheet22with the press member82when the wiring member20and the adherend40are bonded to each other. The thickness of the sheet22in a part where the press trace25is formed may be smaller than that of the sheet22in a part around the part of the press trace25. The thickness of the bonding part50in a part where the press trace25is formed may be smaller than that of the bonding part50in a part around the part of the press trace25. A boundary between the bonding part50and the non-bonding part60is located closer to a side of the non-bonding part60in relation to an edge of the press trace25along the width direction of the sheet22.

The bonding part50includes a pressurized part54and a protrusion part55. The pressurized part54is a part pressed by the press member82. In the present disclosure, a part of the bonding part50overlapped with the press trace25is the pressurized part54. Herein, the press trace25is provided to the surface of the sheet22in the lateral bonding part52, thus the lateral bonding part52includes the pressurized part54.

The protrusion part55is a part protruding to the side of the non-bonding part60along the width direction of the sheet22more than the press trace25in the bonding part50. Herein, the press trace25is formed in a region smaller than the lateral bonding part52, thus the lateral bonding part52includes at least a part of the protrusion part55. Herein, the protrusion part55does not protrude to a region overlapped with the wire-like transmission member26. Thus, herein, the lateral bonding part52includes the whole protrusion part55.

The protrusion part55may include a region overlapped with the wire-like transmission member26. The overlapping bonding part53includes a region in the protrusion part55overlapped with the wire-like transmission member26. When the press trace25is formed to have the same size as the lateral bonding part52along the width direction of the sheet22, the protrusion part55is not included in the lateral bonding part52but is included in the overlapping bonding part53.

The bonding part50is provided between the plurality of spot bonding parts30along the extension direction of the wire-like transmission member26.

FIG.3is a drawing explaining a configuration of the second layer24in the sheet22.FIG.3is a schematic view enlarging the second layer24of the sheet22in a region A inFIG.1.

Herein, the second layer24is a long-fibered non-woven cloth layer24. The non-woven cloth is broadly divided into a short-fibered non-woven cloth and a long-fibered non-woven cloth in accordance with a length of a fiber24fconstituting the non-woven cloth. Examples of the long-fibered non-woven cloth include a spunbond non-woven cloth and a melt-blow non-woven cloth. In the long-fibered non-woven cloth, each fiber24fconstituting the non-woven cloth is long, and the fibers24fare twisted together and extend in a predetermined direction. Accordingly, the long-fibered non-woven cloth layer has a feature that tensile strength along an extension direction D1(an up-down direction in the example inFIG.3) of the fiber24fis higher than that along a direction D2(a right-left direction inFIG.3) perpendicular to the extension direction D1.

At this time, it is sufficient that a dimension of the bonding part50along the direction D2perpendicular to the extension direction D1of the fiber24fis larger than that along the extension direction D1of the fiber24f. When peel force is applied to the bonding part50along the extension direction D1of the fiber24f, the bonding part50withstands the peel force easily by the long-fibered non-woven cloth layer24. When peel force is applied to the bonding part50along the direction D2perpendicular to the extension direction D1of the fiber24f, the bonding part50withstands the peel force easily by the bonding part50itself. In the present example, the sheet22is formed so that the extension direction D1of the fiber24fis the extension direction of the sheet22(the extension direction of the wire-like transmission member26). Thus, the dimension along the width direction of the sheet22is longer than that along the extension direction of the sheet22in the bonding part50.

According to the wiring member-equipped adherend10having the above configuration, the lateral bonding part52is not overlapped with the wire-like transmission member26, thus a heating amount and a pressurizing amount can be increased in forming the lateral bonding part52. Accordingly, the sheet22and the adherend40can be firmly fixed in the lateral bonding part52.

The non-bonding part60where the sheet22and the adherend40are not bonded is provided in the portion overlapped with the wire-like transmission member26adjacent to the bonding part50along the width direction of the sheet22. Accordingly, the whole portion along the width direction of the sheet22is not bonded to the adherend40.

The boundary between the bonding part50and the non-bonding part60is located closer to the side of the non-bonding part60in relation to the edge of the press trace25along the width direction of the sheet22. It is confirmed that the boundary between the bonding part50and the non-bonding part60is located closer to the side of the non-bonding part60in relation to the edge of the press trace25, thus it is easily confirmed that the sheet22and the adherend40are firmly bonded in the lateral bonding part52.

The bonding part50is provided between the plurality of spot bonding parts30along the extension direction of the wire-like transmission member26. Accordingly, a distance from the bonding part50to the spot bonding part30gets larger than a case where the bonding part50is provided in the same region as the spot bonding part30along the extension direction of the wire-like transmission member26. Accordingly, heat and pressure in forming the bonding part50is hardly transmitted to the spot bonding part30.

The metal attached surface42of the adherend40has contact with the hot-melt adhesive agent. Accordingly, the metal attached surface42is heated by induction heating, and the hot melt adhesive agent can be heated by heat transmitted from the attached surface42. Accordingly, heat in forming the bonding part50is hardly transmitted to the wire-like transmission member26. The air layer is provided between the sheet22and the adherend40, thus the heat from the attached surface42is hardly transmitted to the wire-like transmission member26when the attached surface42is induction-heated.

A wiring member-equipped adherend according to an embodiment 2 is described.FIG.4is a cross-sectional view illustrating a wiring member-equipped adherend110according to the embodiment 2. In the following description of the present embodiment, the same reference numerals are assigned to the similar constituent elements described above, and the description thereof will be omitted. The same applies to the description of each embodiment and modification example hereinafter.

The wiring member-equipped adherend110of the present example is different from the wiring member-equipped adherend10described above in that a bonding part150is overlapped with a lateral bonding part152and an overlapping bonding part53is included. As described above, the overlapping bonding part53is provided in a portion overlapped with the wire-like transmission member26. In addition to the overlapping bonding part53, the non-bonding part60is also provided in the portion overlapped with the wire-like transmission member26. The non-bonding part60and the overlapping bonding part53are partially overlapped with the wire-like transmission member26in regions different from each other along the width direction of the sheet122. The overlapping bonding part53is provided adjacent to the lateral bonding part152along the width direction of the sheet122. The overlapping bonding part53is provided between the lateral bonding part152and the non-bonding part60along the width direction of the sheet122.

The overlapping bonding part53is provided in the wiring member-equipped adherend110, thus it is easily confirmed that the sheet122and the adherend40are firmly bonded in the bonding part150by confirming the overlapping bonding part53.

A shape of the sheet122in the present example is different from that of the sheet22described above in that the first layer123is formed to have a smaller length in the width direction than the second layer24. Accordingly, a part of the second layer24is exposed to a first surface of the sheet122in addition to the first layer123. The first layer123is partially provided on the second layer24along the width direction, thus a weight and cost of the sheet122can be reduced compared with a case where the first layer123is provided on the whole second layer24.

In the sheet122, the wire-like transmission member26is disposed on the surface of the first layer123. In the sheet122, the wire-like transmission member26is not disposed in a portion where the first layer123is not located (the surface of the second layer24). In the sheet122, the bonding part150is provided to a portion where the first layer123is not located. A part of the bonding part150protrudes to the portion where the first layer123is located. As illustrated inFIG.4, the lateral bonding part152includes a portion of the bonding part150provided to the portion where the first layer123is not located in the sheet122. The lateral bonding part152includes a part of the bonding part150provided to the portion where the first layer123is located in the sheet22, and the overlapping bonding part53includes the other part thereof.

In the present example, the press trace25is not formed in the surface of the sheet122. The press trace25is hardly marked on the sheet122. A part of the second layer24exposed to the first surface is pressed. At this time, the second layer24is the non-woven cloth layer, thus the press trace25is hardly marked when the second layer24pressed compared with the first layer23as a solid sheet.

The press trace25is hardly marked on the sheet even when force for pressing is weakened. Thus, there may also be a case where the second layer is not exposed to the first surface of the sheet22and the press trace25is not marked on the sheet22also in the wiring member in which the first layer23is pressed as with the wiring member20according to the embodiment 1.

A wiring member-equipped adherend according to an embodiment 3 is described.FIG.5is a plan view illustrating a wiring member-equipped adherend210according to the embodiment 3.

In the present example, a sheet222is formed so that the extension direction D1of the fiber24ffollows a width direction of the sheet222. In this case, it is sufficient that the dimension along an extension direction of the sheet222is longer than that along the width direction of the sheet222in a bonding part250. When peel force is applied to the bonding part250along the extension direction of the sheet222, the bonding part250withstands the peel force easily by the bonding part250itself. When peel force is applied to the bonding part250along the width direction of the sheet222, the bonding part250withstands the peel force easily by the long-fibered non-woven cloth layer24.

In the present example, a bonding part250A provided in one end portion of the sheet222along the width direction and a bonding part250B provided in the other end portion thereof are disposed in positions deviating from each other along the extension direction of the sheet22. An arrangement of the bonding parts250A and250B are a zig-zag arrangement. An arrangement of the bonding part may be a zigzag arrangement in each wiring member-equipped adherend.

FIG.6is a plan view illustrating a modification example of the sheet22. A sheet322according to the modification example is cut out from a raw sheet322B larger than the sheet322. The sheet322is cut out into a shape having a route bending part or a branch part. The wire-like transmission member26is disposed on the sheet322while its route being bended or branched in accordance with the shape of the sheet322.

In this case, an extension part P1along an extension direction of the sheet322and an extension part P2along a width direction thereof may occur in the sheet322. When the extension part P1is fixed to the adherend40, it is sufficient that the extension part P1is fixed by the bonding part50in which a dimension of the sheet322along the width direction is larger than that along the extension direction as with the bonding part50according to the embodiment 1. When the extension part P2is fixed to the adherend40, it is sufficient that the extension part P2is fixed by the bonding part250in which a dimension of the sheet322along the extension direction is larger than that along the width direction as with the bonding part250according to the embodiment 3.

Modification Example

FIG.7is a plan view illustrating a wiring member-equipped adherend410according to a first modification example.FIG.8is a cross-sectional view along a XIII-XIII line inFIG.7.

In the above description, the non-bonding part60is provided adjacent to the bonding part50along the width direction of the sheet22, however, this configuration is not necessary. The non-bonding part60may not be provided adjacent to the bonding part50along the width direction of the sheet22. For example, a bonding part450may be continuously provided over a whole region in a width direction as with a wiring member-equipped adherend410in the present example. In this case, the bonding part450may be provided at intervals along the extension direction of the sheet22. Accordingly, the non-bonding part60is provided adjacent to the bonding part450along the extension direction of the sheet22.

FIG.9is a plan view illustrating a wiring member-equipped adherend510according to a second modification example.

In the above description, the bonding part50is provided between the spot bonding parts30, however, this configuration is not necessary. The bonding part50may be provided in a position of the spot bonding part. For example, as with the wiring member-equipped adherend510in the present example, a bonding part550may be provided to have a length equal to or larger than the interval between the spot bonding parts30along the extension direction of the sheet22, or may also be continuously provided over a whole region in the extension direction of the sheet22. For example, the bonding part50having shorter length than the sheet22along the extension direction of the sheet22may be provided in the same position as the spot bonding part30along the extension direction of the sheet22as with the bonding part50inFIG.1.

A melting point of the sheet22in the lateral bonding part52may be lower than that of the sheet22in the non-bonding part60. Accordingly, a fusion state of the bonding part is hardly resolved even when the lateral bonding part52is formed after the sheet22and the wire-like transmission member26are fused to form the bonding part30.

A heat insulating material may be provided between the sheet22and the adherend40in the non-bonding part60. The heat insulating material may be fixed to both the sheet22and the adherend40, or may also be fixed to only one of the sheet22and the adherend40. The heat insulating material is provided between the sheet22and the adherend40, thus the heat from the attached surface42is hardly transmitted to the wire-like transmission member26when the attached surface42is induction-heated.

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