A wire harness including one or more electrically conductive paths and a resin molded product having a tubular shape which accommodates and protects the one or more electrically conductive paths. The resin molded product includes a first part having clearances along a circumferential direction between an inner surface of the resin molded product and outer surfaces of the one or more electrically conductive paths and a second part having substantially no clearance between the inner surface of the resin molded product and an outer surface of one of the one or more electrically conductive paths in an area along the circumferential directions.
