  • a wiring member comprising a base member and a plurality of linear transmission members arranged side by side on the base member, the plurality of linear transmission members including at least one coated linear transmission member and a plurality of bare electric wires, the coated linear transmission members being arranged between the plurality of bare electric wires.
  • the wiring member (1) includes bare electric wires, so that the material cost for the coating layer of the bare electric wires can be reduced compared to when coated electric wires are used instead of bare electric wires. Since a coated linear transmission member is disposed between multiple bare electric wires, the bare electric wires are prevented from being adjacent to each other, and unintended short circuits between the bare electric wires can be prevented.
  • the height of the coated linear transmission member from the arrangement surface of the base member may be higher than the height of the bare electric wire from the arrangement surface. This allows the coated linear transmission member between the bare electric wires to function as an insulating wall higher than the bare electric wires.
  • the coated linear transmission member has a transmission line body and a coating layer that covers the transmission line body, and the dimensions of the transmission line body in a direction perpendicular to the arrangement surface may be the same as or larger than the dimensions of the bare wire. This allows the difference in height between the coated linear transmission member and the bare wire from the arrangement surface of the base member to be large.
  • the at least one coated linear transmission member may have a first outer linear transmission member arranged on one side of the plurality of linear transmission members arranged in parallel on the base member, and a second outer linear transmission member arranged on the other side. This makes it possible to prevent bare wires from being exposed to the side of the wiring member.
  • the plurality of linear transmission members may have intersections where they cross each other in a plan view, and the intersections may include at least one of a group consisting of a first intersection where the bare electric wires cross, a second intersection where the bare electric wires cross and the coated linear transmission member, and a third intersection where the coated linear transmission members cross. This increases the degree of freedom of the paths of the plurality of linear transmission members on the base member compared to a case where no intersections are provided.
  • the intersection may include the first intersection of the group. This increases the freedom of the bare wire's path on the base member compared to when the first intersection is not provided.
  • the wiring member of (6) may further include an insulating sheet disposed between the bare electric wires that cross each other at the first intersection. This makes it possible for the insulating sheet to prevent short circuits between the bare electric wires at the first intersection.
  • the insulating sheet may be partially provided in an area including the first intersection with respect to the base member. This makes it possible to prevent the insulating sheet from becoming large.
  • the insulating sheet may have higher insulating properties than the base member. This allows the insulating sheet to be thinner than the base member, thereby preventing the wiring member from becoming thicker.
  • the intersection portion includes the first intersection portion and the second intersection portion of the group, the first bare electric wire intersects with the second bare electric wire and the first coated linear transmission member and the second coated linear transmission member on both sides of the second bare electric wire, respectively, to provide the first intersection portion and the second intersection portion, the height of the first coated linear transmission member and the second coated linear transmission member from the arrangement surface of the base member is higher than the height of the second bare electric wire, and at the first intersection portion, there may be a hollow space between the bare electric wires that intersect with each other. This makes it possible to suppress short circuits between the bare electric wires at the first intersection portion without providing an insulating sheet or the like.
  • the intersection may include only the second intersection, only the third intersection, or only the second intersection and the third intersection of the group. This prevents the bare wires from being crossed, making it easier to prevent short circuits between the bare wires.
  • the intersection may include the first intersection, the second intersection, and the third intersection of the group. This increases the degree of freedom of the paths of the bare wires and the coated linear transmission member on the base member.
  • the wiring member may include a first wiring body and a second wiring body stacked on each other, each of the first wiring body and the second wiring body including the base member and the plurality of linear transmission members, and the base member of the first wiring body may be in contact with at least one of the plurality of linear transmission members of the second wiring body. This allows the base member of the first wiring body to be used as a cover member for the plurality of linear transmission members of the second wiring body.
  • the bare electric wire of the first wiring body and the bare electric wire of the second wiring body may have an intersection where they cross each other, and the base member of the first wiring body may be located between the bare electric wire of the first wiring body and the bare electric wire of the second wiring body at the intersection. This allows the base member to prevent short circuits between the bare electric wires at the intersection.
  • the bare wire of the first wiring body and the coated linear transmission member of the second wiring body may overlap each other and extend in the same direction, and the coated linear transmission member of the first wiring body and the bare wire of the second wiring body may overlap each other and extend in the same direction.

  • the wiring member 10 since the wiring member 10 includes the bare electric wire 36, the material cost can be reduced by the coating layer 33 of the bare electric wire 36, compared to the case where the coated electric wire 31 is provided instead of the bare electric wire 36. Since the coated linear transmission member 31 is disposed between the bare electric wires 36, the bare electric wires 36 are prevented from being adjacent to each other, and unintended short circuits between the bare electric wires 36 can be prevented.
  • the width dimension (the distance between the first outer linear transmission member 31L and the second outer linear transmission member 31R) when the multiple linear transmission members 30 are arranged can be reduced compared to the case where a coated electric wire is used instead of the bare electric wires 36. This allows the width dimension of the base member 20 to be reduced, and the material cost can be reduced accordingly.
  • the height of the coated linear transmission member 31 from the arrangement surface 23 is higher than the height of the bare electric wires 36 from the arrangement surface 23. This allows the coated linear transmission member 31 between the bare electric wires 36 to function as an insulating wall higher than the bare electric wires 36. This makes it difficult for conductive dust or dirt to come into contact with the bare electric wires 36 on the other side of the coated linear transmission member 31 when the dust or dirt straddles the coated linear transmission member 31 and the bare electric wires 36 on one side of the coated linear transmission member 31.
  • the dimensions of the transmission line body 32 of the coated linear transmission member 31 are equal to or larger than the dimensions of the bare wire 36. This allows the difference in height between the coated linear transmission member 31 and the bare wire 36 from the placement surface 23 to be large.
  • At least one coated linear transmission member 31 has a first outer linear transmission member 31L arranged on one outer side of the multiple linear transmission members 30 arranged in parallel on the base member 20, and a second outer linear transmission member 31R arranged on the other outer side. This makes it possible to prevent the bare wire 36 from being exposed to the side of the wiring member 10.

  • wiring members 110, 110A, and 110B have intersections where the multiple linear transmission members 30 cross each other in a planar view, which increases the degree of freedom of the paths of the multiple linear transmission members 30 on the base member 20 compared to when no intersections are provided.
  • the intersection includes a first intersection 60. This increases the degree of freedom of the path of the bare wires 36 on the base member 20 compared to a case in which the first intersection 60 is not provided.
  • the intersections include a first intersection 60, a second intersection 61, and a third intersection 62. This increases the degree of freedom of the paths of the bare wires 36 and the coated linear transmission members 31 on the base member 20.
  • the height of the covered electric wires 31B on both sides of the bare electric wire 36B from the arrangement surface 23 is greater than the height of the bare electric wire 36B from the arrangement surface 23, and there is a hollow space between the mutually intersecting bare electric wires 36A, 36B at the first intersection 60. This makes it possible to prevent a short circuit between the bare electric wires 36A, 36B at the first intersection 60 without providing an insulating sheet 70 or the like.

  • the wiring member 210 has an intersection where the bare electric wire 36 of the first wiring body 11 and the bare electric wire 36 of the second wiring body 12 cross each other. As shown in FIG. 11, when the first wiring body 11 bends and branches off from the common path with the second wiring body 12, the bare electric wire 36 of the first wiring body 11 and the bare electric wire 36 of the second wiring body 12 cross each other to provide a first intersection 60.
