     DETAILED DESCRIPTION TO EXECUTE THE INVENTION 
     Description of Embodiments of Present Disclosure 
     First, embodiments of the present disclosure will be listed and described. 
     The wiring member of the present disclosure is as follows. 
     (1) A wiring member according to the present disclosure is a wiring member including a plurality of wires, and a holding member configured to hold the plurality of wires, wherein the plurality of wires include a power line and a communication line that extend in the same direction, the holding member includes a plurality of wire holding portions that each can hold a wire at a fixed position, the power line is held by a first wire holding portion of the plurality of wire holding portions, the communication line is held by a second wire holding portion of the plurality of wire holding portions, and at least one of the plurality of wire holding portions is formed to be capable of retrofittably holding the wire. The power line and the communication line can be positioned using the holding member. In this manner, the positional relationship between the power line and the communication line can be stabilized. Further, at least one of the plurality of wire holding portions is capable of retrofittably holding a wire that is attachable afterwards. In this manner, it is possible to stabilize the positional relationship between the plurality of wires while enabling a wire to be attached afterwards. 
     (2) A configuration is also possible in which the plurality of wire holding portions include a third wire holding portion capable of retrofittably holding a parallel wire that extends in the same direction as the power line and the communication line of the plurality of wires. In this manner, it is possible to hold the parallel wire that is parallel to the power line and the communication line, and stabilize the positional relationship of the parallel wire in addition to the power line and the communication line. Further, the parallel wires can be attached afterwards. For this reason, it is possible to cause the holding member to hold the parallel wires after the wiring including the power line and the communication line and the wiring including the parallel wires are assembled separately. 
     (3) A configuration is also possible in which the holding member further includes a stabilizing mechanism that is in contact with the parallel wire in a state corresponding to a number of the parallel wire and causes the third wire holding portion to hold the parallel wire at a fixed position. In this manner, even if the number of parallel wires varies, it is possible to stabilize the positional relationship of the parallel wires. 
     (4) A configuration is also possible in which the holding member is provided at a plurality of locations spaced apart from each other along a longitudinal direction of the power line and the communication line. In this manner, it is possible to bend the power line and the communication line after attaching the holding member to the power line and the communication line. 
     (5) A configuration is also possible in which the holding member is provided at a location at which the power line and the communication line bend, and regulates the power line and the communication line into a bent state. In this manner, it is possible to regulate the power line and the communication line into a bent state with the holding member. 
     (6) A configuration is also possible in which the power line includes a core wire and an insulating coating that covers the core wire, and the core wire and the insulating coating are formed flat. In this manner, the height dimension of the wiring member can be reduced. 
     (7) The core wire may also be a twisted wire. In this manner, the flatly formed power line can be easily bent. 
     DETAILED DESCRIPTION OF EMBODIMENTS OF DISCLOSURE 
     Specific examples of the wiring member of the present disclosure will be described below with reference to the drawings. It should be noted that the present disclosure is not limited to these examples, but is indicated by the scope of the claims, and all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein. 
     First Embodiment 
     Hereinafter, a wiring member according to a first embodiment will be described.  FIG. 1  is a plan view showing a wiring member  10  according to the first embodiment.  FIG. 2  is a cross-sectional view taken along line II-II in  FIG. 1 . 
     The wiring member  10  is provided with a plurality of wires  20  and a holding member  30 . The holding member  30  holds the plurality of wires  20  in a state of being positioned at a fixed position. 
     Here, each of the wires  20  is an insulated wire. The insulated wire includes a core wire  21  and an insulating coating  22  that covers the core wire  21 . The wiring member  10  may include a cable in which a plurality of insulated wires are covered with a sheath. 
     The core wire  21  is formed using a conductor such as copper, a copper alloy, aluminum, or an aluminum alloy as the material. The core wire  21  may be a single core wire constituted by a single strand. The core wire  21  may include a plurality of strands. If the core wire  21  includes a plurality of strands, the strands may or may not be twisted. 
     The insulating coating  22  is formed by an insulating material. Typically, the insulating coating  22  is formed by a resin such as polyvinyl chloride (PVC) or polyethylene (PE). The insulating coating  22  may be formed through press-molding a resin around the core wire  21 , or applying an insulating paint such as enamel around the core wire  21 . The insulating coating  22  is formed in a shape conforming to the shape of the core wire  21 . The insulating coating  22  is favorably formed at approximately the same thickness around the core wire  21 . 
     The plurality of wires  20  include a power line  23  and communication lines  24 . The power line  23  and the communication lines  24  extend in the same direction. In the following description, if the power line  23  and the communication lines  24  need to be distinguished from each other, the reference signs  23  and  24  may be referred to, and if the power line  23  and the communication lines  24  do not need to be distinguished from each other, they may be collectively called the wires  20 . 
       FIG. 3  is a front view showing the power line  23  according to the first embodiment. The power line  23  is a wire for supplying power to a connection destination of the wiring member  10 . The core wire  21  and the insulating coating  22  of the power line  23  are formed flat. The core wire  21  of the power line  23  is a twisted wire  21   a . The twisted wire  21   a  is formed by twisting a plurality (seven in the example shown in  FIG. 3 ) of strands  21   b . One or a plurality (eight in the example shown in  FIG. 3 ) of the twisted wires  21   a  are included. In the example shown in  FIG. 3 , the plurality of twisted wires  21   a  collectively form one conductive path. Here, the twisted wires  21   a  are not flat. The plurality of strands  21   b  are twisted such that the lateral cross-sections of the twisted wires  21   a  are formed in approximately circular shapes. Here, since the plurality of twisted wires  21   a  are arranged flat, the core wire  21  is formed flat. However, the twisted wires  21   a  may be formed flat. In the example shown in  FIG. 3 , the eight twisted wires  21   a  are arranged side by side in a row. The plurality of twisted wires  21   a  may be arranged in a plurality of rows as long as the twisted wires  21  are arranged flat. The twisted wires  21   a  are in contact with each other inside the insulating coating  22 . However, the twisted wires  21   a  may also separate from each other inside the insulating coating  22 , and in contact with each other at a portion that has no insulating coating  22  such as an end portion of the power line  23 . The flat core wire  21  of the power line  23  may be a flat plate. The flat core wire  21  of the power line  23  may also be formed by the plurality of strands  21   b  being arranged so as to extend in parallel to each other. 
     The communication lines  24  are wires for transmitting signals between the destinations to which the wiring member  10  is connected. The communication lines  24  are not formed flat. The communication lines  24  are round wires. The communication lines  24  may also be flat wires. 
     Here, the allowable current value of the power line  23  is set higher than the allowable current value of the communication lines  24 . For this reason, the transverse cross-sectional area of the core wire  21  of the power line  23  is larger than the lateral cross-sectional area of the core wire  21  of the communication line  24 . 
     In the example shown in  FIG. 2 , the one power line  23  is provided. The one power line  23  is a power line on the positive side, for example. However, the number of the power line  23  is not limited to this. Two or more power lines  23  may also be provided. Two or more power lines  23  only on the positive side may be provided. In other words, a plurality of power lines for a plurality of different circuits may be included. Two or more power lines including a power line on the negative side may be provided. That is, a power line for one closed circuit may be included. Note that, in some cases, the power line on the positive side is simply called a power line, and the power line on the negative side is called a ground line. 
     In the example shown in  FIG. 2 , two communication lines  24  are provided. The two communication lines  24  are communication lines  24  for CAN (Controller Area Network) communication, for example. Note that the number of the communication lines is not limited to this. One or three or more communication lines may be provided. If one communication line is provided, the communication line is a communication line for LIN (Local Interconnect Network) communication, for example. The above describes an example in which the communication line includes one bus wiring. The communication line may include a plurality of bus wirings. 
       FIG. 4  is a front view showing the holding member  30  according to the first embodiment. The holding member  30  includes a plurality of wiring holding portions  32 . Each of the plurality of wire holding portions  32  can hold the wire  20  at the fixed position. The wire holding portions  32  each include a housing space in which the wires  20  can be held at a fixed position. The first wire holding portion  33  and the second wire holding portion  34  are included in the plurality of wire holding portions  32 . In the following description, if the first wire holding portion  33  and the second wire holding portion  34  need to be distinguished from each other, the reference signs  33  and  34  are referred to, and if the first and second wire holding portions  33  and  34  do not need to be distinguished from each other in particular, the first and second wire holding portions  33  and  34  may be collectively called the wire holding portions  32 . The power line  23  is held in the first wire holding portion  33 . The communication lines  24  are held in the second wire holding portion  34 . The holding member  30  is a member formed in one piece through molding using a material such as a resin. 
     At least one of the plurality of wire holding portions  32  is formed such that the wire  20  can be retrofittably held. Here, the first wire holding portion  33  and the second wire holding portion  34  are formed such that the wire  20  can be attached and retrofittably held. The state in which the wire  20  can be attached afterwards means that the wire  20  that is to be attached afterwards and the holding member  30  are not formed in one piece. The state in which the wire  20  can be attached afterwards can also be understood as a state in which the holding member  30  can hold the wire  20  that was formed separately from the holding member  30 . The wire holding portion  32  to which the wire  20  can be attached afterwards may be formed such that the wire  20  can be held in an attachable/detachable manner. Here, the first wire holding portion  33  and the second wire holding portion  34  are formed such that the wire  20  can be held in an attachable/detachable manner. The wire  20  being attachable/detachable means that the wire  20  can be attached afterwards and the wire  20  that is held by the holding member  30  can be detached from the holding member  30  without the holding member  30  being broken. Accordingly, the wire  20  being attachable afterwards includes a case in which the wire  20  can be attached and detached, and a case in which the holding member  30  needs to be broken when the wire  20  held by the holding member  30  is detached from the holding member  30 . 
     The first wire holding portion  33  is formed in a groove shape. The first holding portion includes the bottom wall  33   a  and a pair of side walls  33   b . The pair of side walls  33   b  are provided so as to stand at the two edges of the bottom wall  33   a . The space between the leading end portions of the side walls  33   b  is open. The power line  23  can be inserted through the opening. The housing space of the first wire holding portion  33  is formed in a shape that conforms to the power line  23 . Here, the side walls  33   b  are formed longer than the bottom wall  33   a . In other words, the dimension from the opening to the bottom wall  33   a  is longer than the dimension between the pair of the side walls  33   b . The bottom wall  33   a  is formed to have a length corresponding to the thickness of the power line  23 . The side walls  33   b  are formed to have a length corresponding to the width of the power line  23 . However, the side walls  33   b  may be formed shorter than the bottom wall. In other words, the dimension from the opening to the bottom wall may be shorter than the dimension between the pair of side walls. In this case, the bottom wall is formed to have the length corresponding to the width dimension of the power line  23 . The side walls are formed to have the width corresponding to the width dimension of the power line  23 . 
     The first wire holding portion  33  is provided with pressing pieces  36 . The pressing pieces  36  are provided at the leading ends of the side walls  33   b . The pressing pieces  36  protrude so as to cover the opening of the first wire holding portion  33 . The pressing pieces  36  protrude toward the opposing side wall  33   b . The pressing pieces  36  are provided at positions of the pair of side walls  33   b  that are spaced apart from the bottom wall  33   a  by the same length dimension. Note that, the pressing pieces  36  may be only formed on one of the pair of side walls  33   b.    
     The pressing pieces  36  are provided at a plurality of positions that are at different distances from the bottom wall  33   a . In this manner, as shown in  FIG. 4 , it is possible to house multiple kinds of power lines  23  with various width dimensions at a fixed position. Specifically, the pressing pieces  36  provided at a plurality of positions are called pressing pieces  36 A,  36 B, and  36 C in order from a position close to the bottom wall  33   a . Also, multiple kinds of power lines  23  having different widths are called power lines  23 A,  23 B, and  23 C in ascending order of width. In this case, when the power line  23 A is fully housed in the first wire holding portion  33 , the pressing pieces  36 A act as detents of the power line  23 A. Similarly, when the power line  23 B is fully housed in the first wire holding portion  33 , the pressing pieces  36 B act as detents of the power line  23 B. Similarly, when the power line  23 C is fully housed in the first wire holding portion  33 , the pressing pieces  36 C act as detents of the power line  23 C. It is favorable that, when the power line  23 C corresponding to the pressing pieces  36 C is housed in the first wire holding portion  33 , the pressing pieces  36 A and  36 B that are closer to the bottom wall  33   a  can elastically deform toward the side walls  33   b  to which the base end portion is connected. In this manner, the side walls  33   b  are unlikely to protrude outward when the power line  23 C is housed in the first wire holding portion  33 . 
     The second wire holding portion  34  is provided on the outer surface of the first wire holding portion  33 . Here, the second wire holding portion  34  is provided on the outer surface of the side wall  33   b , but may also be provided on the outer surface of the bottom wall  33   a . The second wire holding portion  34  includes a first wall  34   a  that protrudes from the first wire holding portion  33  and a second wall  34   b  that protrudes from the leading end of the first wall  34   a . The second wire holding portion  34  is formed in an L shape. The second wall  34   b  extends along the outer surface of the first wire holding portion  33  at a position spaced apart from the outer surface of the first wire holding portion  33 . The space between the leading end of the second wall  34   b  and the outer surface of the first wire holding portion  33  is open. The communication lines  24  can be inserted through this opening. The second wire holding portion may be formed so as to include a plurality of walls provided at intervals on the outer surface of the first wire holding portion  33 . In this case, the outer surface of the first wire holding portion  33  forms the bottom of the housing space of the second wire holding portion. 
     The housing space of the second wire holding portion  34  is formed to be capable of collectively housing the two communication lines  24 . Here, the second wall  34   b  is formed longer than the first wall  34   a . That is, the dimension from the opening to the first wall  34   a  is longer than the dimension from the second wall  34   b  and the outer surface of the first wire holding portion  33 . However, the second wall may also be formed shorter than the first wall. That is, the dimension between the second wall and the outer surface of the first wire holding portion  33  may be formed shorter than the dimension from the opening to the first wall. 
     The second wire holding portion may separately house a plurality of communication lines  24  that form a plurality of bus wirings. The second wire holding portion in this case is formed in a T shape that further includes a third wall that extends in the opposite direction to the second wall  34   b , for example. 
     The second wire holding portion  34  is provided with a pressing piece  37 . The pressing piece  37  is provided at the leading end of the second wall  34   b . The pressing piece  37  protrudes so as to cover the opening of the second wire holding portion  34 . The pressing piece  37  protrudes toward the outer surface of the first wire holding portion  33 . The pressing piece  37  may be formed on the outer surface of the first wire holding portion  33 . 
     The first wire holding portion  33  and the second wire holding portion  34  respectively hold the power line  23  and the communication lines  24  in a state of being spaced apart from each other. In this manner, noise in the communication lines  24  due to the power line  23  is likely to be a fixed value. At this time, the power line  23  and the communication lines  24  may be spaced apart from each other to an extent that a shield is not required. A shield may also be provided between the power line  23  and the communication lines  24 . At least one of the power line and communication lines may be a shield wire in which the circumstance of the core wire  21  is covered by a shield. 
     The holding member  30  is provided with a fixing portion  39  for fixing the wiring member  10  to the attachment target. In the example shown in  FIG. 2 , the fixing portion  39  is a clip  39 . The clip  39  can be inserted and fixed to a hole that is formed in the target. The clip  39  includes a column  39   a  and a locking piece  39   b . The column  39   a  is formed protruding from the wire holding portion  32 . The locking piece  39   b  is provided at a leading end of the column  39   a . The locking piece  39   b  is provided to laterally expand from the column  39   a . The locking piece  39   b  is formed larger than the hole. When the clip  39  is inserted into the hole and the locking piece  39   b  abuts against the circumferential edge portion of the hole, the locking piece  39   b  can elastically deform to contract to be smaller than the hole by receiving a force from the circumferential edge portion of the hole. Furthermore, the locking piece  39   b  can elastically restore so as to expand to be larger than the hole after passing the hole. In this manner, the clip  39  can be inserted and locked to the hole. 
     The fixing portion  39  is provided at the outer surface on the side wall  33   b . The fixing portion  39  may also be provided on the outer surface of the bottom wall  33   a . The fixing portion  39  is provided on the side wall  33   b  that is opposite to the side wall  33   b  on which the second wire holding portion  34  is provided. The fixing portion  39  may also be provided on the same side wall  33   b  to the side wall  33   b  on which the second wire holding portion  34  is provided. 
     The column  39   a  of the clip  39  extends in the thickness direction of the flat power line  23 . The column of the clip may be provided so as to extend in the width direction of the flat power line  23 . 
     Note that, the holding member  30  need not necessarily be provided with the fixing portion  39 . Also, even if the holding member  30  is provided with a fixing portion, the fixing portion need not necessarily be the clip  39 . The fixing portion may also be a hole, for example. Due to the bolt passing into the hole or the clip being inserted into the hole, the holding member  30  is fixed to the target. 
     The holding members  30  are provided at a plurality of positions spaced apart from each other along the longitudinal direction of the power line  23  and the communication lines  24 . The power line  23  and the communication lines  24  are bent between the two holding members  30 . In the example shown in  FIG. 1 , the power line  23  and the communication lines  24  bend in the direction along the flatly-formed main surface of the power line  23 . However, the power line  23  and the communication lines  24  may bend in another direction other than this. The power line  23  and the communication lines  24  may bend in the normal direction with respect to the flatly formed main surface of the power line  23 . The power line  23  and the communication lines  24  may also bend in the direction in which the power line  23  is twisted. The power line  23  and the communication lines  24  may be bent at a plurality of positions. The plurality of positions may be between the one pair of the holding members  30  or between another pair of holding members  30 . At each position, the direction in which the lines bend may be the same or different. Further, in the example shown in  FIG. 1 , although the power line  23  and the communication lines  24  bend at a 90°, but the bending angle may also be another value. 
     &lt;Variation of Wiring Member&gt; 
       FIG. 5  is a front view showing a variation of the wiring member  10  according to a first embodiment. The wiring member  110  according to the variation is provided with a plurality of wires  20  and a holding member  130 . The plurality of wires  20  according to the present embodiment are different from the plurality of wires  20  according to the first embodiment in that parallel wires  25  are further included. The holding member  130  is different from the above holding member  30  in that a third wire holding portion  35  is further included in the plurality of wire holding portion  32 . 
     The parallel wires  25  are wires that extend in the same direction as the power line  23  and the communication lines  24 . One or a plurality (seven in the example shown in  FIG. 5 ) of parallel wires  25  are provided. The parallel wires  25  may include a wire that supplies power, similarly to the power line  23 , a wire that transfers signals, similarly to the communication lines  24 , or may include both of these types of wires. In the example shown in  FIG. 5 , the plurality of parallel wires  25  are in the same size, but the parallel wires  25  may be different in size. 
     The third wire holding portion  35  is capable of retrofittably holding the parallel wires  25 . Similarly to the second wire holding portion  34 , the third wire holding portion  35  is formed in an L shape including the first wall  35   a  and the second wall  35   b . Here, the second wire holding portion  34  is provided on the outer surface of the bottom wall  33   a , and the third wire holding portion  35  is provided on the outer surface of the side wall  33   b . Accordingly, in the second wire holding portion  34 , the first wall  34   a  protrudes from the outer surface of the bottom wall  33   a , and the second wall  34   b  extends along the outer surface of the bottom wall  33   a  at a position spaced apart from the outer surface of the bottom wall  33   a . In the third wire holding portion  35 , the first wall  35   a  protrudes from the outer surface of the side wall  33   b , and the second wall  35   b  extends along the outer surface of the side wall  33   b  at a position spaced apart from the outer surface of the side wall  33   b . However, the second wire holding portion  34  and the third wire holding portion  35  may also be provided on the outer surface of the same side wall  33   b.    
     The second wall  35   b  of the third wire holding portion  35  is formed longer than the second wall  34   b  of the second wire holding portion  34 . In this manner, the third wire holding portion  35  can hold more wires than the second wire holding portion  34 . 
     The holding member  30  further includes a stabilizing mechanism  40 . The stabilizing mechanism  40  is provided in the third wire holding portion  35 . The stabilizing mechanism  40  is in contact with the parallel wires  25  in a state corresponding to the number of the parallel wires  25  and causes the third wire holding portion  35  to hold the parallel wires  25  in a fixed position. In the example shown in  FIG. 5 , the stabilizing mechanism  40  includes a plurality of pressing pieces  42 . The plurality of pressing pieces  42  are provided on the inner surface of the second wall  35   b . The plurality of pressing pieces  42  are provided at a plurality of positions that are at different distances from the first wall  35   a . In this manner, even if the number of parallel wires  25  varies, the parallel wires  25  can be housed in a fixed position. 
     Specifically, the pressing pieces  42  provided at a plurality of positions are pressing pieces  42 A,  42 B, and  42 C in order from the position close to the first wall  35   a . Four of the parallel wires  25  can be housed between the first wall  35   a  and the pressing piece  42 A. Two of the parallel wires  25  can be housed between the pressing piece  42 A and the pressing piece  42 B. One of the parallel wires  25  can be housed between the pressing piece  42 B and the pressing piece  42 C. In this manner, even if the parallel wires  25  varies in number, different numbers of parallel wires  25  can be appropriately held at a fixed position in the third wire holding portion  35 . 
     Specifically, if there is one parallel wire  25 , the parallel wire  25  is housed between the pressing piece  42 B and the pressing piece  42 C. If there are two parallel wires  25 , the parallel wires  25  are housed between the pressing piece  42 A and the pressing piece  42 B. If there are three parallel wires  25 , two of the parallel wires  25  are housed between the pressing piece  42 A and the pressing piece  42 B, and one of the parallel wires  25  is housed between the pressing piece  42 B and the pressing piece  42 C. If there are four parallel wires  25 , the parallel wires  25  are housed between the first wall  35   a  and pressing piece  42 A. If there are five parallel wires  25 , four of the parallel wires  35   a  are housed between the first wall  35   a  and the pressing piece  42 A, and one of the parallel wire  25  is housed between the pressing piece  42 B and the pressing piece  42 C. If there are six parallel wires  25 , four of the parallel wires  25  are housed between the first wall  35   a  and the pressing piece  42 A, and two of the parallel wires  35   a  are housed between the pressing piece  42 A and the pressing piece  42 B. If there are seven parallel wires  25 , four of the parallel wires  25  are housed between the first wall  35   a  and the pressing piece  42 A, and two of the parallel wires  25  are housed between the pressing piece  42 A and the pressing piece  42 B, and one of the parallel wires  25  is housed between the pressing piece  42 B and the pressing piece  42 C. 
     Of course, the number and arrangement of the plurality of pressing pieces  42  that form the stabilizing mechanism  40  in the third wire holding portion  35  are not limited to the above. For example, the pressing pieces  42  may be two or four or more. Also, the space between the pressing pieces  42  and the number of wires to be housed between the pressing pieces  42  and the first wall  35   a  can be set as appropriate. 
     &lt;Effects of First Embodiment and the Like&gt; 
     According to the present embodiment, the power line  23  and the communication lines  24  can be positioned by the holding members  30  and  130 . In this manner, the positional relationship between the power line  23  and the communication lines  24  can be stabilized. At least one of the plurality of wire holding portions  32  is formed to be to be capable of retrofittably holding the wire  20 . In this manner, it is possible to stabilize the positional relationship between the plurality of wires  20  while enabling the wire  20  to be attached afterwards. Due to the positional relationship between the power line  23  and the communication lines  24  being stabilized, the state of noise that occurs in the communication lines  24  due to the power line  23  is stabilized. For this reason, it is possible to eliminate the need of a measure against the noise, or to simplify the measure against the noise even if it is needed. 
     The holding members  30  and  130  are provided at a plurality of locations spaced apart from each other along the longitudinal direction of the power line  23  and the communication lines  24 . In this manner, it is possible to bend the power line  23  and the communication lines  24  after attaching the holding member  30 . 
     Since the power line  23  is formed flat, the height dimension of the wiring member  10  can be reduced. Since the core wire  21  of the power line  23  is the twisted wire  21   a , the flatly formed power line  23  can be readily bent. 
     Furthermore, with the holding member  130 , the third wire holding portion  35  in the holding member  130  can hold the parallel wires  25 . In this manner, it is possible to stabilize the power line between the parallel wires  25 , as well as the power line  23  and the communication lines  24 . Furthermore, the third wire holding portion  35  is capable of retrofittably holding the parallel wires  25 . For this reason, after the wiring including the power line  23  and the communication lines  24  and the wiring including the parallel wires  25  are separately assembled, the parallel wires  25  can be held by the holding member  130 . Since the stabilizing mechanism  40  is formed in the third wire holding portion  35 , even if the number of the parallel wires  25  varies, the positional relationship between the parallel wires  25  can be stabilized. 
     Second Embodiment 
     The wiring member according to a second embodiment will be illustrated.  FIG. 6  is a plan view showing the wiring member  210  according to the second embodiment.  FIG. 7  is a cross-sectional view taken along line VI-VI in  FIG. 6 . Note that, in the description of the present embodiment, the constituent elements that are similar to those described above will be given the identical reference signs and the descriptions thereof will be omitted. 
     In this example, the shape of the holding member  230  is different from the shapes of the above holding members  30  and  130 . Specifically, the holding member  230  is the same as the above holding member  130  in that the wire  20  can be attached to a third wire holding portion  235  afterwards. The holding member  230  is different from the above holding members  30  and  130  in that a first wire holding portion  233  and second wire holding portions  234  are not formed such that the wire  20  can be attached afterwards. The holding member  230  is formed in one piece with the power lines  23  and the communication lines  24 . 
     Specifically, in this example, the two power lines  23  are provided. The two power lines  23  are held by the holding member  230  at the positions spaced apart from each other in the thickness direction. The communication line  24  is located between the power lines  23 . The two communication lines  24  are arranged in the same direction as the direction in which the two power lines  23  are arranged. The communication line  24  is located at an intermediate portion in the width direction of the power lines  23 . 
     The holding member  230  is formed in an H-shape in which three plate-like portions are combined. The two of the three plate-like portions are first wire holding portions  233 , and the other one is a second wire holding portion  234 . It can be regarded that the two first wire holding portion  233  are provided to be spaced apart from each other. Also, it can be regarded that the second wire holding portion  234  is provided at a location that connects the intermediate portions of the first wire holding portions  233 . Note that, the holding member  230  can be configured such that at least one of the power lines  23  and the communication lines  24  can be attached thereto afterwards. In this case, for example, a groove that can house the power lines  23  or the communication lines  24  attached afterwards can be formed in the plate-like portions. 
     The spaces between the end portion in the width direction of the two first wire holding portions  233  are open. The spaces surrounded by the two first wire holding portion  233  and the second wire holding portion  234  are third wire holding portions  235 . Two third wire holding portions  235  are provided. The two third wire holding portions  235  can house the parallel wires  25  respectively. 
     Stabilizing mechanisms  240  are respectively provided in the third wire holding portion  235 . The stabilizing mechanisms  240  are different from the above stabilizing mechanism  40  in that the stabilizing mechanisms  240  hold the parallel wires  25  in an elastically deformed state. Specifically, the stabilizing mechanism  240  includes elastic pieces  44 . The elastic pieces  44  may be formed by an elastic material such as elastomer including rubber. The elastic pieces  44  may be elastically formed as porous such as a foamed resin including a sponge. The elastic pieces  44  may be elastically formed like a plate spring. The elastic pieces  44  are provided so as to face each other. The elastic pieces  44  are provided on the inner surfaces of the two first wire holding portions  233 . The parallel wires  25  can be sandwiched and held between the elastic pieces  44 . However, the elastic pieces may be provided at only one of the two first wire holding portions  233 . The elastic pieces  44  facing each other are spaced apart from each other and prevented from contacting each other. However, the elastic pieces  44  facing each other may also be in contact with each other. 
     The plurality of elastic pieces  44  are provided so as to be arranged from the second wire holding portion  234  side toward the opening on the inner surface of the one first wire holding portions  233 . However, only one elastic piece may be provided on the inner surface of the one first wire holding portion  233 . A configuration is also possible in which one elastic piece has the same size as the interval between the two first wire holding portions  233  and is fully housed in the third wire holding portion  235 . In this case, a slit that runs from the opening toward the bottom portion of the third wire holding portion  235  is favorably formed in each of the elastic pieces. The parallel wires  25  are inserted and held in these slits. 
       FIG. 8  is an illustrative diagram showing how the parallel wires  25  are housed in the holding member  230 . In the example shown in  FIG. 8 , six parallel wires  25  are housed in one of the two third wire holding portions  235 , and three parallel wires  25  are housed in the other third wire holding portion  235 . In this case, the deformation amount of the elastic pieces  44  in the third wire holding portion  235  in which the six parallel wires  25  are housed is larger than the deformation amount of the elastic piece  44  in the third wire holding portion  35  in which the three parallel wires  25  are housed. In other words, the stabilizing mechanism  240  can hold parallel wires  25  of different numbers at fixed positions due to the deformation amount of the elastic pieces  44  changing. 
     As shown in  FIG. 6 , the holding member  230  is provided at a position at which the power line  23  and the communication lines  24  bend. The holding member  230  regulates the power line  23  and the communication lines  24  into a bent state. The holding member  230  can receive a reactive force of the power line  23  and the communication lines  24  that attempt to return to straight from a bent state. For example, after the holding member  230  is linearly formed in one piece with the power lines  23  and the communication lines  24 , the holding member  230  is bent and deformed at the temperature at which the holding member  230  can easily deform, the holding member  230  is cooled to be fixed in this state, and thus the holding portion can be held in a state in which the holding portion is deformed by bending. Of course, the holding member  230  need not necessarily be provided at the position at which the power line  23  and the communication lines  24  can bend, and the power line  23  and the communication lines  24  may only be provided at partial locations at which the power line  23  and the communication lines  24  linearly extend. 
     &lt;Effects of Second Embodiment and the Like&gt; 
     According to the second embodiment as well, except for the operation and effects due to the holding members  30  and  130  dispersedly being arranged, similar operation and effects to the above first embodiment can be obtained. 
     According to the second embodiment, the holding member  230  is provided at a location at which the power line  23  and the communication line  24  bend. The holding member  230  regulates the power line  23  and the communication line  24  in the bent state. 
     Application Example to Vehicle 
       FIG. 9  is an illustrative diagram showing an example in which the wiring members  10 ,  110 , and  210  are applied to a vehicle. In the example shown in  FIG. 9 , one end portion and the other end portion of the power lines  23  and the communication lines  24  are connected to the same devices  80  and  81 . The power lines  23  and the communication lines  24  extend on the same path from the one end portion to the other end portion. The holding members  30 ,  130 , and  230  are provided in at least part of the intermediate portion excluding the end portion (portion of connector C) which is connected to the devices  80  and  81  of the power lines  23  and the communication lines  24 . Here, the holding members  130  and  230  that can hold the parallel lines  25  are provided. 
     The one end portions of the parallel lines  25 A are connected to the device  80  which is the same as the device to which the power lines  23  and the communication lines  24  are connected. The other end portion of the parallel lines  25 A is connected to the device  82  that is different from the devices  80  and  81  to which the power lines  23  and the communication lines  24  are connected. The one end portion and the other end portion of the parallel line  25 B is connected to devices  83  and  84  which are different from the devices  80  and  81  to which the power lines  23  and the communication lines  24 . Accordingly, a portion of the paths of the parallel lines  25 A and  25 B is the same as the paths of the power lines  23  and the communication lines  24 . Another portion of the parallel lines  25 A and  25 B are different from the paths of the power lines  23  and the communication lines  24 . Note that the one end portion and the other end portion of the parallel lines may be connected to the devices  80  and  81  that are the same device to which the power line  23  and the communication lines  24  are connected. 
     It is preferable that the holding members  130  and  230  that can house the parallel wires  25  are attached to a portion of the paths of the power lines  23  and the communication lines  24  that overlap with the paths of the parallel wires  25 A and  25 B. In this manner, the holding members  130  and  230  can hold the parallel wires  25 . A configuration is also possible in which the holding member  30  that can house the parallel wire  25  is attached to a portion of the paths of the power line  23  and the communication lines  24  that do not overlap with the path of the parallel wire  25 . 
     For example, the devices  80  and  81  to which the power lines  23  and the communication lines  24  are connected are conceivably a power supply communication relay device. The power supply communication relay device is a device that distributes the power supply to one or a plurality of devices  82  that are connected thereto, and relays communication between the one or plurality of devices  82  that are connected thereto. In this case, the power lines  23  are conceivably wires for supplying power to the power supply communication relay device. That is, the power lines  23  are wires for supplying power to the power supply distribution devices  80  and  81 . For this reason, a comparatively large current flows through the power lines  23 . Also, a voltage of 12 V is applied to the power lines  23 , for example. Also, the communication lines  24  are conceivably a communication bus line (bus wiring). 
     For example, the parallel wires  25 A are wires that connect the device  80  that is a power supply communication relay devices and the device  82 . The device  82  is conceivably a body device, an information/entertainment device, or the like. The body device and the information/entertainment device are devices that are not directly related to traveling of an automobile. The body devices include various kinds of illumination devices, various kinds of actuators, operation switches thereof, and the like that are mounted in the automobile. The illumination devices conceivably include head lights, small lumps, brake lamps, fog lamps, interior lights, and the like, and the actuators conceivably include actuators such as power windows, and power slide doors. The information/entertainment devices are conceivably a music or movie reproduction equipment, speakers, auxiliary communication devices, and a navigation device. The parallel wires  25 A may include the power lines or the communication lines, and are applied in accordance with the function of the device  82 . 
     For example, the parallel wires  25 B are wires that connect the devices  83  and  84  that are other than power supply communication relay devices. The devices  83  and  84  conceivably include driving devices, safety devices, and automatically operation devices. The driving devices are, for example, devices relating to steering, acceleration, and braking. The safety devices are, for example, devices relating to a safety driving assisting function such as an automatic braking system, an airbag, and the like. The automatic operation devices are devices relating to automatic operation of sensors (a perimeter monitoring camera, a distance sensor such as a radar) that monitors the periphery of an automotive. The parallel wires  25 B may include the power lines or the communication lines, and are applied in accordance with the devices  83  and  84 . 
     It is preferable that the body device, the information/entertainment device can be easily changed according to preference and the like of the user, in other words, easily customized From this viewpoint, it is preferable that the parallel wires  25 A can be attached and detached to/from the third wire holding portions  35 ,  235  of the holding members  130 ,  230 . Compared with the body device and information/entertainment device, the drive device, the safety device, the automatic operating device, and the like have less need to be easily customized From this viewpoint, it suffices if the parallel wires  25 B can be attached to the third wire holding portions  35 ,  235  of the holding members  130 ,  230  afterwards, and the parallel wires  25 B have less need to be attachable/detachable. Of course, the parallel wires  25 B can be attached and detached to/from the third wire holding portion  35  and  235 . In this case, maintenance of the parallel wires  25 B can be facilitated. A configuration is also possible in which both the attachable/detachable wire holding portion and the wire holding portion that can be attached afterwards and cannot be attached and detached are provided as the third wire holding portion. Further, a configuration is also possible in which the parallel wires  25 A are held by the wire holding portion to which wires are attachable/detachable, and the parallel wires  25 B are by the wire holding portion to which wires are attachable afterwards but not attachable/detachable. 
     Variation 
     In the above description, it is assumed that the power lines  23  are formed flat, but the power lines  23  need not necessarily be flat. For example, the power lines  23  may also be round wires or the like. 
     Note that the configurations described in the above embodiments and variations can be combined with each other as long as no mutual contradiction arises.
