SUPPORT MEMBER-ATTACHED WIRE HARNESS AND WIRE HARNESS SUPPORT STRUCTURE

A support member-attached wire harness includes a wire harness including an electrical wire and a support member that includes a fitting portion formed in a partially cylindrical shape that is opened partially in a circumferential direction so as to be capable of being fitted to an outer peripheral portion of a bar-shaped member. On at least one of the wire harness and the support member, a support portion for supporting the wire harness disposed along an outer periphery of the fitting portion at a fixed position with respect to the fitting portion is formed.
