A wire harness is provided with an electrically conductive path, a tubular sheath member which accommodates the electrically conductive path in an inner part, and a sheet member positioned between at least a part of a circumferential direction of the electrically conductive path and an inner peripheral surface of the sheath member. The sheet member may be wound on the electrically conductive path so as to cover an entire area in the circumferential direction. The sheet member may be intermittently arranged in an axial direction of a tube of the sheath member.
