     DESCRIPTION OF EMBODIMENT(S) 
     Description of Embodiment of Present Disclosure 
     Embodiments of the present disclosure are listed and described firstly. 
     A wiring member according to the present disclosure is as follows. 
     (1) A wiring member includes: a sheet; a first wire-like transmission member fixed to the sheet; and at least one second wire-like transmission member having lower rigidity than the first wire-like transmission member and fixed to the sheet, wherein an intersection part of the first wire-like transmission member and the second wire-like transmission member is provided on the sheet, and the first wire-like transmission member is located closer to a side of the sheet than the second wire-like transmission member in the intersection part. The first wire-like transmission member having higher rigidity than the second wire-like transmission member is located on a side of the sheet in the intersection part. Thus, the first wire-like transmission member can be continuously fixed to the sheet in a section including the intersection part, or can be fixed to the sheet at a small fixation interval. Accordingly, the first wire-like transmission member is hardly detached from the sheet in the section including the intersection part. 
     (2) In the wiring member according to (1), it is also applicable that the first wire-like transmission member is any of a power source wire, a ground wire, a shield wire, and a multicore wire, and the second wire-like transmission member is a single-core signal wire. Accordingly, the first wire-like transmission member as any of the power source wire, the ground wire, the shield wire, and the multicore wire is hardly detached from the sheet. 
     (3) In the wiring member according to (1) or (2), the first wire-like transmission member may intersect with the plurality of second wire-like transmission members in a parallel route part where the plurality of second wire-like transmission members are parallelly arranged. Accordingly, the plurality of second wire-like transmission members suppress deviation of the first wire-like transmission member from the sheet. 
     (4) In the wiring member according to any one of (1) to (3), a covering layer of each of the first wire-like transmission member and the second wire-like transmission member may be fused to the sheet. Accordingly, the first wire-like transmission member and the plurality of second wire-like transmission members are simply fixed to the sheet. 
     Details of Embodiment of Present Disclosure 
     Specific examples of a wiring member of 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. 
     Embodiment 1 
     A wiring member according to an embodiment 1 is described hereinafter.  FIG.  1    is a schematic plan view illustrating a wiring member  10  according to the embodiment 1.  FIG.  2    is a partial enlarged view of  FIG.  1   .  FIG.  3    is a cross-sectional view of the wiring member cut along a III-III line in  FIG.  2   . A portion illustrated by a virtual line in  FIG.  2    and  FIG.  3    are fixing parts FP. 
     The wiring member  10  includes a sheet  20  and a plurality of wire-like transmission members  30 . The plurality of wire-like transmission members  30  are fixed to the sheet  20 . The sheet  20  is formed into a flat shape as a whole. The plurality of wire-like transmission members  30  are fixed to the sheet  20 , thus the wiring member  10  is kept in a flat state. 
     The sheet  20  needs only fix the plurality of wire-like transmission members  30 , thus a material and a structure, for example, are not particularly limited. With regard to a material constituting the sheet  20 , the sheet  20  is 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 sheet  20 . With regard to the structure of the sheet  20 , the sheet  20  has a double layer structure herein. The structure of the sheet  20  may be a single layer structure, or a multilayer structure of three or more layers is also applicable. 
     The sheet  20  includes a first layer  22  and a second layer  24 . The first layer  22  is a fusion layer. The wire-like transmission member  30  is fused and fixed to the fusion layer. The fusion layer includes a resin material, or preferably includes a thermoplastic resin material. The resin material of the fusion layer is 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 layer is not particularly limited. For example, the fusion layer may 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 layer is also considered a foam sheet, for example. The fusion layer is 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 layer  22  is one main surface of the sheet  20 . 
     The second layer  24  is formed of a material different from that of the fusion layer, or has a different structure. The second layer  24  increases a function of the fusion layer, or adds a function which the fusion layer does not have to the sheet  20 . A material constituting the second layer  24  is a material described for the fusion layer described above, metal, or an inorganic material, for example. A structure of the second layer  24  may be any of the structure described for the fusion layer described above. One surface of the second layer  24  is the other main surface of the sheet  20 . 
     The first layer  22  and the second layer  24  are fixed to each other while the other surface of the first layer  22  and the other surface of the second layer  24  have contact with each other. A fixing state of the first layer  22  and the second layer  24  is not particularly limited, however, fixing by fusion or adhesion is preferable. For example, when at least one of the first layer  22  and the second layer  24  is 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 layer  22  and the second layer  24  are rigidly fixed. 
     In the description herein, the first layer  22  is a solid sheet made of resin and the second layer  24  is a fibrous material sheet. In the description herein, the first layer  22  and the second layer  24  are fused to each other. That is to say, the resin of the first layer  22  enters between the fibers of the second layer  24  while having flowability, and is then hardened. Maintained accordingly is a state where the resin of the first layer  22  enters between the fibers of the second layer  24 , and the first layer  22  and the second layer  24  are rigidly fixed to each other. 
     The first layer  22  and the second layer  24  are formed to have the same size (the same planar shape). One of the first layer  22  and the second layer  24  may also be formed to be larger than the other one thereof. The first layer  22  and the second layer  24  are wholly fixed at a region where they have contact with each other. The first layer  22  and the second layer  24  may also be fixed only at a part of a region where they have contact with each other. 
     The sheet  20  may be a flexible member. For example, the first layer  22  is a solid sheet made up of flexible resin such as flexible PVC as a material, the second layer  24  is a non-woven cloth made up of PET as a material, and the sheet  20  is a flexible member. For example, the sheet  20  may have a plastic property so as to be able to follow bending of the wire-like transmission member  30 . It is also applicable that the wiring member  10  can be bended in a thickness direction (bending so that a fold line follows the main surface of the sheet  20 ). 
     The plurality of wire-like transmission members  30  are wire-like members transmitting electrical power or light, for example. The plurality of wire-like transmission members  30  are assumed to be members connecting components in a vehicle. A connector C, for example, is provided on an end portion of the wire-like transmission member  30 . This connector C is connected to a connector provided in the other side component, thus the wire-like transmission member  30  is connected to the other side component. That is to say, the present wiring member  10  is used as the wiring member  10  electrically connecting various types of component in a vehicle, for example (or connecting them so that they can perform optical communication). The connector C may be fixed to the sheet  20 . 
     Routes of the plurality of wire-like transmission members  30  are set in accordance with a position of a component to which the wire-like transmission members  30  are connected. The plurality of wire-like transmission members  30  are fixed to the sheet  20 , thus the plurality of wire-like transmission members  30  are kept in a form following a wiring route corresponding to a position of a component as a connection destination of each wire-like transmission member  30 . The route of the plurality of wire-like transmission members  30  may be made up of a combination of a straight route and a bending route. The sheet  20  may also be made up of a combination of a straight route and a bending route. The plurality of wire-like transmission members  30  may be fixed to the sheet  20  in a state where a branch wire is branched from a main wire. The sheet  20  may 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. Herein, the plurality of wire-like transmission members  30  are bended on the sheet  20 . The plurality of wire-like transmission members  30  are branched on the sheet  20 . 
     The wire-like transmission member  30  includes a transmission wire body  31  and a covering layer  32 . The transmission wire body  31  is a portion transmitting electrical power or light. When the wire-like transmission member  30  is an electrical wire, the transmission wire body  31  is 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. When the wire-like transmission member  30  is an optical fiber, the transmission wire body  33  is a core and a clad. The covering layer  32  is a layer covering the transmission wire body  31 . A resin material constituting the covering layer  32  is not particularly limited, but can be appropriately set. For example, the wire-like transmission member  30  may 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 member  30  transmitting the electrical power may be various kinds of signal wires or various kinds of power wires. Some of the wire-like transmission members  30  transmitting 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 member  30  may 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  30  with one transmission route. The wire-like transmission member  30  may be a multicore wire. The multicore wire is a compound body of a plurality of wire-like objects. The single core wire is the wire-like transmission member  30  with 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  36 , for example. 
     Herein, the wire-like transmission member  30  is fused and fixed to the sheet  20 . In this case, an outermost layer of the wire-like transmission member  30  and a fusion layer are fused to each other. An outermost layer of the wire-like transmission member  30  is a covering layer  32 . The covering layer  32  is made up of a material which can be fused to the fusion layer. A resin material constituting the covering layer  32  and a resin material constituting the fusion layer are the same type of material. A resin material constituting the fusion layer and a resin material constituting the covering layer  32  are PVC or polyolefin, for example. However, a fixing state of the wire-like transmission member  30  and the sheet  20  is not limited to fusion. The fixing state other than fusion is described in detail in modification examples described hereinafter. 
     The plurality of fixing parts FP where the sheet  20  and the wire-like transmission member  30  are fixed are provided at intervals along the extension direction of the wire-like transmission member  30 . The interval between the fixing parts FP is not particularly limited, but can be appropriately set. However, the fixing parts FP where the sheet  20  and the wire-like transmission member  30  are fixed may be continuously provided along the direction in which the wire-like transmission member  30  extends. 
     Herein, eight wire-like transmission members  30  are included. The eight wire-like transmission members  30  are divided into two wire-like transmission members  30 A, two wire-like transmission members  30 B, and four wire-like transmission members  30 C. The two wire-like transmission members  30 A intersect with the two wire-like transmission members  30 B, respectively, in a first intersection region A 1 . The two wire-like transmission members  30 A and the two wire-like transmission members  30 B intersect with the four wire-like transmission members  30 C, respectively, in a second intersection region A 2 . The first intersection region A 1  and the second intersection region A 2  are provided in positions away from each other along the extension direction of the wire-like transmission member  30 A. Only one of the first intersection region A 1  and the second intersection region A 2  may be provided. 
     In the present specification, a portion where two wire-like transmission members  30  intersect with each other on the sheet  20  is referred to as an intersection part  40 . A portion where two wire-like transmission members  30 A and  30 B intersect with each other is referred to as an intersection part  40 AB hereinafter. A portion where two wire-like transmission members  30 A and  30 C intersect with each other is referred to as an intersection part  40 AC. A portion where two wire-like transmission members  30 B and  30 C intersect with each other is referred to as an intersection part  40 BC. 
     The plurality of wire-like transmission members  30  include two or more types of wire-like transmission member having rigidity different from each other. In a combination of two wire-like transmission members having different rigidity, a wire-like transmission member having higher rigidity is referred to as a first wire-like transmission member and a wire-like transmission member having lower rigidity is referred to as a second wire-like transmission member. A degree of rigidity of the two wire-like transmission members  30  may be obtained by an amount of bending of a test piece with a predetermined length supported in a predetermined posture at a time of applying predetermined load to a predetermined position in the test piece, for example. 
     The rigidity of the wire-like transmission member  30  is determined by a compositive combination of a plurality of conditions such as a layer structure of the wire-like transmission member  30 , a material and structure of the transmission wire body  31 , and a material and structure of the covering layer  32 , for example. 
     For example, it is assumed that two wire-like transmission members  30  of a single-core general wire and a single-core shield wire have the same condition except for a layer structure. In this case, rigidity of the single-core shield wire tends to be generally higher than that of the single-core general wire. The single-core general wire is an electrical wire made up of one conductor core wire and one covering layer. The single-core shield wire is an electrical wire in which a shield layer and a second covering layer are further provided on a single-core general wire. 
     For example, it is assumed that two wire-like transmission members  30  of a single-core general wire and a multicore wire have the same condition except for the number of cores. That is to say, the multicore wire is a compound body of a plurality of single-core general wires. In this case, rigidity of the multicore wire tends to be generally higher than that of the single-core general wire. 
     For example, it is assumed that two wire-like transmission members  30  having different conductor cross-sectional area have the same condition except for the conductor cross-sectional area. In this case, rigidity of the wire-like transmission member  30  having a larger conductor cross-sectional area tends to be generally higher than that of the wire-like transmission member  30  having a smaller conductor cross-sectional area. Herein, when each of a power source wire, a ground wire, and a signal wire are made up of a single-core general wire, the power source wire and the ground wire tend to have a larger conductor cross-sectional area than the signal wire. Thus, the power source wire and the ground wire tend to have higher rigidity than the signal wire. The reason is that the power source wire and the ground wire are used for a circuit for supplying electrical power to an actuator, for example, in some cases, and such a circuit needs to have a large conductor cross-sectional area so that large current can flow therein. 
     For example, it is assumed that two wire-like transmission members  30  of a copper electrical wire in which a material of the transmission wire body  31  is copper and an aluminum electrical wire in which a material of the transmission wire body  31  is aluminum have the same condition except for the material of the transmission wire body  31 . In this case, rigidity of the aluminum electrical wire tends to be generally higher than that of the copper electrical wire. 
     For example, it is assumed that two wire-like transmission members  30  having substantially the same conductor cross-sectional area and having a different number of strands have the same condition except for the number of strands of the transmission wire body  31 . In this case, rigidity of the wire-like transmission member  30  having a smaller number of strands tends to be generally higher than that of the wire-like transmission member  30  having a larger number of strands. 
     One of the two wire-like transmission members  30  constituting one intersection part  40  located on a side of the sheet  20  is referred to as a lower side wire-like transmission member, and the other one of the two wire-like transmission members  30  is referred to as an upper side wire-like transmission member in some cases. Focusing on rigidity of the lower side wire-like transmission member and the upper side wire-like transmission member constituting the intersection part  40 , the intersection part  40  is divided into three intersection parts of a first intersection part, a second intersection part, and a third intersection part. The first intersection part is an intersection part in which the lower side wire-like transmission member has higher rigidity than the upper side wire-like transmission member. The second intersection part is an intersection part in which the upper side wire-like transmission member has higher rigidity than the lower side wire-like transmission member. The third intersection part is an intersection part in which the lower side wire-like transmission member has the same rigidity as the upper side wire-like transmission member. 
     In the example illustrated in  FIG.  2   , four intersection parts  40  in the first intersection region A 1  are all intersection parts  40 AB. In the first intersection region A 1 , the wire-like transmission members  30 A and  30 B intersect with each other to change an order of arrangement. The wire-like transmission members  30 A and  30 B are parallel to each other in both sides of the first intersection region A 1 . 
     The wire-like transmission member  30 A has higher rigidity than the wire-like transmission member  30 B. Accordingly, the wire-like transmission member  30 A is the first wire-like transmission member and the wire-like transmission member  30 B is the second wire-like transmission member in a combination of the wire-like transmission members  30 A and  30 B. The wire-like transmission member  30 A is the lower side wire-like transmission member located on a side of the sheet  20  and the wire-like transmission member  30 B is the upper side wire-like transmission member in the intersection part  40 AB. Accordingly, all of the intersection parts  40 AB are the first intersection parts. 
     The wire-like transmission member  30 A extends straight in a section including the intersection part  40 AB. The wire-like transmission member  30 B extends to be curved in a section including the intersection part  40 AB. A route of the wire-like transmission member  30 A is longer than that of the wire-like transmission member  30 B in a section including the intersection part  40 AB in the parallel route part. In this manner, it is sufficient that the route of the second wire-like transmission member is disposed to be longer than that of the first wire-like transmission member in a section including the intersection part  40  in which the two wire-like transmission members  30  changes their order of arrangement. 
     In the example illustrated in  FIG.  2   , eight intersection parts  40  in sixteen intersection parts  40  in the second intersection region A 2  are the intersection parts  40 AC and eight intersection parts  40  are the intersection parts  40 BC. In the second intersection region A 2 , the wire-like transmission members  30 A,  30 B, and  30 C intersect with each other to be branched. The wire-like transmission members  30 A,  30 B, and  30 C are parallel to each other in one side of the second intersection region A 2 . The wire-like transmission members  30 A and  30 B and the wire-like transmission member  30 C extend in different directions in the other side of the second intersection region A 2 . The wire-like transmission members  30 A and  30 B and the wire-like transmission member  30 C may also extend in different directions in the other side of the second intersection region A 2 . 
     The wire-like transmission member  30 A has higher rigidity than the wire-like transmission member  30 C. Accordingly, the wire-like transmission member  30 A is the first wire-like transmission member and the wire-like transmission member  30 C is the second wire-like transmission member in a combination of the wire-like transmission members  30 A and  30 C. The wire-like transmission member  30 A is the lower side wire-like transmission member located on a side of the sheet  20  and the wire-like transmission member  30 C is the upper side wire-like transmission member in the intersection part  40 AC. Accordingly, all of the intersection parts  40 AC are the first intersection parts. 
     The wire-like transmission member  30 B has the same rigidity as the wire-like transmission member  30 C. Thus, there is no first wire-like transmission member and the second wire-like transmission member in the combination of the wire-like transmission members  30 B and  30 C. All of the intersection parts  40 BC are the third intersection parts. The wire-like transmission member  30 B is the lower side wire-like transmission member located on a side of the sheet  20  and the wire-like transmission member  30 C is the upper side wire-like transmission member in the intersection part  40 BC. 
     In the example illustrated in  FIG.  2   , all of the plurality of intersection parts  40 AB and  40 AC set in one wire-like transmission member  30 A are the first intersection parts. Some of the plurality of intersection parts  40 AB and  40 BC set in one wire-like transmission member  30 B are the first intersection parts and the other some of the intersection parts  40 BC are the third intersection parts. In the similar manner, some intersection parts  40 AC in the plurality of intersection parts  40 AC and  40 BC set in one wire-like transmission member  30 C are the first intersection parts, and the other some intersection parts  40 BC are the third intersection parts. In this manner, the plurality of intersection parts in one wire-like transmission member  30  may include some of the first intersection parts, the second intersection parts, and the third intersection parts. 
     When the wire-like transmission member  30  constituting the first intersection part constitutes the second intersection part or the third intersection part in the other intersection part  40  in the same intersection region, it is sufficient that the wire-like transmission member  30  as the upper side wire-like transmission member in the first intersection part is the upper side wire-like transmission member also in the second intersection part or the third intersection part. For example, the wire-like transmission member  30 C constituting the first intersection part in the intersection part  40 AC constitutes the third intersection part in the other intersection part  40 BC in the same intersection region. The wire-like transmission member  30 C is the upper side wire-like transmission member in the intersection parts  40  of any of the intersection parts  40 AC and  40 BC. In the similar manner, when the wire-like transmission member  30  constituting the first intersection part constitutes the second intersection part or the third intersection part in the other intersection part  40  in the same intersection region, it is sufficient that the wire-like transmission member  30  as the lower side wire-like transmission member in the first intersection part is the lower side wire-like transmission member also in the second intersection part or the third intersection part. 
     It is also applicable that the first wire-like transmission member is any of a power source wire, a ground wire, a shield wire, and a multicore wire, and the second wire-like transmission member is a single-core signal wire. Herein, one of the two wire-like transmission members  30 A is a power source wire, and the other one thereof is a ground wire. The power source wire and the ground wire are wires supplying electrical power to an apparatus. The power source wire is an electrical wire on a plus side. The ground wire is an electrical wire on a minus side. When a body earth, for example, is adopted, the ground wire may be omitted. The remaining wire-like transmission members  30 B and  30 C are all single core signal wires. 
     As illustrated in  FIG.  2   , the plurality of second wire-like transmission members are provided. The plurality of second wire-like transmission members are parallelly arranged in the parallel route part. The first wire-like transmission member intersects with the plurality of second wire-like transmission members in the parallel route part. The plurality of second wire-like transmission members press the first wire-like transmission member. Specifically, four wire-like transmission members  30 C are parallelly arranged in the second intersection region A 2 . Each of two wire-like transmission members  30 A intersects with the four wire-like transmission members  30 C. Each of the two wire-like transmission members  30 A is pressed by the four wire-like transmission members  30 C. 
     Effect etc. of Embodiment 1 
     According to the wiring member  10  having the above configuration, the wire-like transmission member  30 A having higher rigidity than the wire-like transmission members  30 B and  30 C is located on the side of the sheet  20  in the intersection parts  40 AB and  40 AC. Thus, the wire-like transmission member  30 A can be continuously fixed to the sheet  20  in a section including the intersection parts  40 AB and  40 AC, or can be fixed to the sheet  20  at a small fixation interval. Accordingly, the wire-like transmission member  30 A is detached more hardly from the sheet  20  in the section including the intersection parts  40 AB and  40 AC. Herein, the wire-like transmission member  30 A as a power source wire or a ground wire is detached more hardly from the sheet  20 . 
     The wire-like transmission member  30 A having high rigidity hardly follows bending of the sheet  20  compared with the wire-like transmission members  30 B and  30 C having low rigidity when the sheet  20  is bended, for example, thus is easily detached from the sheet  20 . A portion detached from the sheet  20  and cannot be fixed to the sheet  20  occurs in a section including the intersection part  40  in the upper side wire-like transmission member in the two wire-like transmission members  30  having the intersection part  40 . In contrast, the lower side wire-like transmission member can have contact with the sheet  20  in the section including the intersection part  40 , and can be fixed thereto. Thus, when the wire-like transmission member  30 A having high rigidity is applied to the lower side wire-like transmission member, the wire-like transmission member  30 A can have contact with the sheet  20  in the section including the intersection parts  40 AB and  40 AC, and can be fixed thereto, thus is hardly detached from the sheet  20 . 
     The wire-like transmission member  30 A intersects with the plurality of wire-like transmission members  30 C in the parallel route part, thus the plurality of wire-like transmission members  30 C suppresses deviation of the wire-like transmission member  30 A from the sheet  20 . 
     The covering layer  32  of each of the wire-like transmission members  30  are fused to the sheet  20 , thus the wire-like transmission member  30  is simply fixed to the sheet  20 . 
     Modification Example 
       FIG.  4    is a cross-sectional view illustrating a modification example of the wiring member  10 . In the wiring member  110  illustrated in  FIG.  4   , the wire-like transmission member  130 A is a shield wire. The wire-like transmission member  130 A includes the transmission wire body  31 , a first covering layer  32   a,  a shield layer  33 , and the second covering layer  32   b.  The transmission wire body  31 , the first covering layer  32   a,  the shield layer  33 , and the second covering layer  32   b  are stacked in this order from an inner side to an outer side. A configuration similar to the transmission wire body  31  and the covering layer  32  in the wiring member  10  can be adopted to the transmission wire body  31  and the first covering layer  32   a.  The shield layer  33  is not particularly limited. For example, the shield layer  33  may be a conductor foil. The conductor foil may be spirally wound or vertically attached. For example, the shield layer  33  may be a braided wire. The braided wire may be formed into a cylindrical shape. The second covering layer  32   b  is an outermost layer of the wire-like transmission member  130 A. When the second covering layer  32   b  is fused to the fusion layer, the second covering layer  32   b  is preferably a material which can be fused to the fusion layer. 
     The wire-like transmission member  130 A has higher rigidity than the wire-like transmission member  30 C. Accordingly, the wire-like transmission member  130 A is the first wire-like transmission member and the wire-like transmission member  30 C is the second wire-like transmission member in a combination of the wire-like transmission members  130 A and  30 C. The wire-like transmission member  130 A is the lower side wire-like transmission member and the wire-like transmission member  30 C is the upper side wire-like transmission member in the intersection part  140 AC of the wire-like transmission member  130 A and the wire-like transmission member  30 C. Accordingly, the intersection part  140 AC is the first intersection part. Also in this case, the wire-like transmission member  130 A as a shield wire is hardly detached from the sheet  20 . 
       FIG.  5    is a cross-sectional view illustrating another modification example of the wiring member  10 . In the wiring member  210  illustrated in  FIG.  5   . the wire-like transmission member  230 A is a multicore wire. The wire-like transmission member  230 A illustrated in  FIG.  5    includes two transmission routes. The wire-like transmission member may be a multicore wire having three or more transmission routes. The wire-like transmission member  230 A includes two covering electrical wires  35 . The two covering electrical wire  35  is covered by the sheath  36 . Accordingly, the wire-like transmission member  230 A is a multicore wire with the sheath  36 . 
     The wire-like transmission member  230 A has higher rigidity than the wire-like transmission member  30 C. Accordingly, the wire-like transmission member  230 A is the first wire-like transmission member and the wire-like transmission member  30 C is the second wire-like transmission member in a combination of the wire-like transmission members  230 A and  30 C. The wire-like transmission member  230 A is the lower side wire-like transmission member and the wire-like transmission member  30 C is the upper side wire-like transmission member in the intersection part  240 AC between the wire-like transmission member  230 A and the wire-like transmission member  30 C. Accordingly, the intersection part  240 AC is the first intersection part. Also in this case, the wire-like transmission member  230 A as a multicore wire is hardly detached from the sheet  20 . 
     In the above description, the wire-like transmission member  30  on the sheet  20  is the first wire-like transmission member or the second wire-like transmission member, however, this configuration is not necessary. For example, the third wire-like transmission member which does not intersect with the other wire-like transmission member  30  may be provided on the sheet  20 . The third wire-like transmission member may extend along the same route as the first wire-like transmission member or the second wire-like transmission member on the sheet  20 . The third wire-like transmission member may extend along a route different from the first wire-like transmission member or the second wire-like transmission member on the sheet  20 . 
     Described in the above description is the example that the wiring members  10 ,  110 , and  210  do not include the second intersection part, however, this configuration is not necessary. The wiring member may include the second intersection part. When the plurality of intersection parts  40  are located on the sheet  20 , it is sufficient that at least one intersection part  40  is the first intersection part. 
     In the example described in the embodiment 1, one wire-like transmission member  30  intersects with a different wire-like transmission member  30  at a plurality of positions. That is to say, the plurality of intersection parts  40  are set in one wire-like transmission member  30 . However, only one intersection part may be set in one wire-like transmission member. 
     Described in the embodiment 1 is the example that the wire-like transmission member  30 A intersects with the plurality of wire-like transmission member  30 C in the parallel route part, however, this configuration is not necessary. The wire-like transmission member  30 A may intersect with one wire-like transmission member  30 . 
     In the example described in the embodiment 1, two types of the wire-like transmission member  30  having different rigidity are provided, however, there may be also a case where three or more types of wire-like transmission member  30  having different rigidity are provided in one wiring member  10 . For example, considered is a case where provided are three type of wire-like transmission member, that is, a wire-like transmission member having high rigidity, a wire-like transmission member having middle rigidity, and a wire-like transmission member having low rigidity in descending order of the rigidity. In this case, the wire-like transmission member having high rigidity is the first wire-like transmission member and the wire-like transmission member having middle rigidity is the second wire-like transmission member in a combination of the wire-like transmission member having high rigidity and the wire-like transmission member having middle rigidity. The wire-like transmission member having high rigidity is the first wire-like transmission member and the wire-like transmission member having low rigidity is the second wire-like transmission member in a combination of the wire-like transmission member having high rigidity and the wire-like transmission member having low rigidity. The wire-like transmission member having middle rigidity is the first wire-like transmission member and the wire-like transmission member having low rigidity is the second wire-like transmission member in a combination of the wire-like transmission member having middle rigidity and the wire-like transmission member having low rigidity. In this manner, the wire-like transmission member having middle rigidity may be the first wire-like transmission member or the second wire-like transmission member depending on the other side member in combination. In this manner, the plurality of intersection parts in the wire-like transmission member having middle rigidity may include the first intersection part and the second intersection part. 
     When three or more types of the wire-like transmission member having different rigidity are provided in one wiring member, the wire-like transmission member having highest rigidity in the wire-like transmission member constituting the intersection part may be a lower side electrical wire part in all of the plurality of intersection parts constituting the wire-like transmission member. The wire-like transmission member having lowest rigidity in the wire-like transmission member constituting the intersection part may be an upper side electrical wire part in all of the plurality of intersection parts constituting the wire-like transmission member. 
     As described above, applicable as the fixing state of the sheet  20  and the wire-like transmission member  30  is fusion fixation, or a fixing state other than the fusion fixation is also applicable. Applicable as the fixing state of the sheet  20  and the wire-like transmission member  30  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 sheet  20  and the wire-like transmission member  30  have 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 member  30  toward the sheet  20  or sandwiches the sheet  20  and the wire-like transmission member  30  to keep them in a fixing state. 
     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 sheet  20  and the wire-like transmission member  30  are indirectly stuck and fixed via an adhesive agent, a gluing agent, and a double-sided adhesive tape provided therebetween. The contact area direct fixation indicates that the sheet  20  and the wire-like transmission member  30  are 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 sheet  20  and the wire-like transmission member  30  is melted, thus the sheet  20  and the wire-like transmission member  30  are 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 fusion can be used. For example, when the contact area direct fixation by heat is formed by fusion, adoptable are various types of fusion means such as ultrasonic fusion, heating pressurizing fusion, hot air fusion, and high-frequency fusion. When the state of the contact area direct fixation is formed by these means, the sheet  20  and the wire-like transmission member  30  are in the state of the contact area direct fixation by these means. Specifically, when the state of the contact area direct fixation is formed by the ultrasonic fusion, for example, the sheet  20  and the wire-like transmission member  30  are in the state of the contact area direct fixation by the ultrasonic fusion. Accordingly, the fusion fixation described above is one aspect of the contact area direct fixation. 
     The configurations described in the embodiments and modification examples thereof can be appropriately combined as long as they are not contradictory.
