WIRE HARNESS

A wire harness includes a cable that includes electric wires and a sheath covering the electric wires and is arranged so that the electric wires are exposed from an end portion of the sheath, a housing that accommodates the electric wires exposed from the end portion of the sheath, wire seal members arranged inside the housing to seal between the electric wires and the housing, a holder that includes an elastic body, a cylindrical sheath-side cylinder portion including an inner circumferential surface in contact with an outer circumferential surface of the sheath, and a cylindrical housing-side cylinder portion in contact with an outer circumferential surface of the housing, the sheath-side cylinder portion and the housing-side cylinder portion being integrally formed, and a first pressing member that presses the housing-side cylinder portion toward the housing and thereby fixes the housing-side cylinder portion to the housing.
