WIRE HARNESS AND METHOD FOR MANUFACTURING SAME

The purpose of the present invention is to reduce size and improve heat dissipation performance. A wire harness in which the outermost of a plurality of circuits includes a metal pipe body (20) and an insulating body (21) provided on the outer circumferential side of the metal pipe body (20) . The metal pipe body (20) is expanded in an exterior member (16) into an expanded state, whereby the outer surface of the insulating body (21) makes intimate contact with the inner surface of the exterior member (16).
