A routing configuration of a wire harness includes an outer member having a tubular shape, and at least one conductive path configured to be contained in and protected by the outer member. In a generally straight wiring portion, the wire harness is routed in such a manner that the outer member is snaked so that portions of an inner surface of the outer member are brought into contact with the at least one conductor path, the generally straight wiring portion being defined as a portion where the wire harness is routed generally straightly between bent wiring portions which are defined as portions where the wire harness is routed being bent so as to conform to shapes of corresponding portions of a routing target, respectively.
