A plurality of wire-like transmission members is easily fixed to a base member. The wiring member includes an assembled wire made up of a plurality of bundled wire-like transmission members and a base member in which the assembled wire is fixed on the main surface.

A wiring member includes: a first electric wire; a braided wire that surrounds the first electric wire; a second electric wire; a resin; a sheath; and a ground wire that is electrically continuous with the braided wire. The braided wire surrounds the first electric wire, the second electric wire, and the braided wire. The sheath has a first end exposing the first electric wire, the second electric wire, and the braided wire. The braided wire has a second end exposing the first electric wire away from the first end. The resin seals, in a liquid-tight manner, the sheath and a region covered by the sheath, and the braided wire and a region surrounded by the braided wire. The first electric wire, the second electric wire, and the ground wire are exposed from the resin.

An electrical conductor assembly includes an electrical conductor, an electrically insulating jacket disposed around a conductor section of the electrical conductor, an electrically conductive sleeve disposed around a first insulating jacket section of the insulating jacket, and an electrically conductive yarn for realizing an electric field control. The electrically conductive yarn is wound around a second insulating jacket section of the electrically insulating jacket in adjacent relation to the first insulating jacket section.

Ribbon cables including a plurality of spaced apart substantially parallel conductors extending along a length of the cable and arranged along a width of the cable, and first and second insulative layers disposed on opposite sides of and substantially coextensive with the plurality of conductors along the length and width of the cable are described. Each insulative layer may be adhered to the conductors and may include alternating substantially parallel thicker and thinner portions extending along the length of the cable. The thicker portions of the first and second insulative layers are substantially aligned in one to one correspondence. Each corresponding thicker portion of the first and second insulative layers have at least one conductor in the plurality of conductors disposed therebetween. The thicker portions may have an effective dielectric constant less than 2.

It is aimed to provide a communication cable which includes a solid sheath on an outer periphery of a signal cable having a plurality of insulated wires and in which transmission characteristics hardly decrease due to a pressure in extrusion-molding a sheath. A communication cable 1 is provided with a signal cable 10 including a plurality of insulated wires 11 each having a conductor 12 and an insulation coating 13 covering an outer periphery of the conductor 12, and a solid sheath 20 covering an outer periphery of the signal cable 10.

To provide an insulated wire that can increase in a partial discharge starting voltage, prevent deterioration of an insulator, and not cause worsening of an occupancy ratio, a coil that uses the insulated wire, a variable-thickness insulating tape used in manufacture of the insulated wire, and a manufacturing method of the same. The above-described problem is solved by an insulated wire (10) for a coil, comprising a conductor (1), and insulating coatings (2, 3) provided on an outer periphery of the conductor (1). The insulated wire (10) is constituted by the thick insulating coating (3) for an area where voltage increases and partial discharge readily occurs, and the thin insulating coating (2) for an area where the voltage does not increase and partial discharge does not readily occur, when the coil is wound. The thick insulating coating (3) and the thin insulating coating (2) are repeatedly provided at desired intervals. The above-described problem is solved by a coil (40) obtained by winding such an insulated wire (10) and configured so that the insulating coating (3) of the insulated wire (10) in an area where partial discharge readily occurs is thick, and the insulating coating (2) of the insulated wire (10) in an area where partial discharge does not readily occur is thin.
