A wiring member includes a twisted wire in which a first wire-like transmission member and a second wire-like transmission member are stranded and a base member to which the twisted wire is fused and fixed. Each of the first wire-like transmission member and the second wire-like transmission member is fused to the base member in each of the side-by-side parts in which the first wire-like transmission member and the second wire-like transmission member are arranged side by side on the base member in the twisted wire to form a side-by-side fusion part. A length of a first half cycle section including the side-by-side fusion part is larger than a length of a second half cycle section located adjacent to the first half cycle section.

A method of forming a flexible circuit, including providing a flexible flat cable with a first surface and a second surface. The first surface of the flexible flat cable is diametrically opposed to the second surface. A dispensing apparatus including a nozzle is further provided, and an extruded material is dispensed through the nozzle onto the first surface of the flexible flat cable. The extruded material is shaped into a pattern and cured onto the first surface of the flexible flat cable.

A wiring member includes a sheet, a holding member fixed to the sheet, and a first wire-like transmission member held by the holding member. The holding member includes a holding part in which a groove and a protrusion narrowing a width dimension of an opening part of the groove are formed. The first wire-like transmission member is housed in the groove.

Elongated conductors are provided. Aspects of the elongated conductors include: an elongated structure having a proximal region and a distal region, where the elongated conductor includes two or more insulated conducting members that are in fixed relative position along at least a portion of the elongated structure and extend from the proximal region to the distal region. A pattern of insulation openings among the insulated conducting members is present at one or both of the proximal and distal regions. Aspects of the invention further include methods of making the elongated conductors, as well as devices that include the elongated conductors.

A flexible flat cable includes a base film extending in a first direction and having a first length, a conductive wire portion on a first surface of the base film and extending in the first direction, a cover film on the conductive wire portion, extending in the first direction and exposing a part of the conductive wire portion, the cover film having a second length which is less than the first length and a first conductive tape comprising a first tape area on a surface of the cover film and extending in the first direction and a second tape area folded at a certain angle from the first tape area and having a third length.

Elongated conductors are provided. Aspects of the elongated conductors include: an elongated structure having a proximal region and a distal region, where the elongated conductor includes two or more insulated conducting members that are in fixed relative position along at least a portion of the elongated structure and extend from the proximal region to the distal region. A pattern of insulation openings among the insulated conducting members is present at one or both of the proximal and distal regions. Aspects of the invention further include methods of making the elongated conductors, as well as devices that include the elongated conductors.

A wiring member includes: a wiring body including a base member and a normal wire fused to the base member; and a special wire fixed to the wiring body via a fixing part. The fixing part is fixed in a fixing state different from fusion between the base member and the special wire.

A wiring member includes: a wire-like transmission member (for example, an electric wire); a first sheet member including one main surface to which the wire-like transmission member is fixed; and a second sheet member fixed to the first sheet member on a side of another main surface of the first sheet member. The first sheet member is suitable for fixing of the wire-like transmission member in comparison to the second sheet member. One member of the first sheet member and the second sheet member includes a space into which another member being melted can be filled. The first sheet member and the second sheet member overlap each other with the another member out of the first sheet member and the second sheet member being melted, filled and then solidified in the space of the one member.

An improved plastic-cladding filament structure includes a combined arrangement of a base layer, thermosetting polymer glue, and at least one conductive filament. The thermosetting polymer glue is combined with the base layer. The at least one conductive filament is enclosed and housed in the thermosetting polymer glue to allow the conductive filament to be attached to the base layer through heating and setting of the thermosetting polymer glue. By means of the property the thermosetting polymer glue that the thermosetting polymer glue gets set after being heated to a predetermined temperature and melted and shaped and once heated to get set and shaped, further heating does not change the shape, the thermosetting polymer glue that encloses and houses the conductive filament can be set to form any desired shape to facilitate combination thereof with the base layer.

A wiring member includes a first sheet including a fusion layer, a second sheet, and at least one first wire-like transmission member provided between the first sheet and the second sheet. The first sheet and the second sheet are fixed to each other via the fusion layer in a direction intersecting with a longitudinal direction of the first wire-like transmission member.
