That portion of a wire harness, corresponding to an installation path region E1 where a cable is not required to have flexibility, includes rigid wires 1 each having a single conductor 1a, and a metal shielding case 2 covering outer peripheries of the rigid wires 1. Each of those portions of the wire harness, corresponding respectively to installation path regions E2 where the cable is required to have flexibility, includes flexible wires 4, and a flexible shielding member 5 covering outer peripheries of the flexible wires 4. Conductors 4a of the flexible wires 4 are connected to the conductors 1a of the rigid wires 1, and the metal protector 2 is connected to the flexible shielding members 5.
