A wire harness is constructed by bundling a plurality of electric wires in which conductors are surrounded with insulating coatings respectively. The electric wires are constructed of aluminum electric wires in which the conductors consist of aluminum or aluminum alloy and copper electric wires in which the conductors consist of copper or copper alloy. A plurality of the aluminum electric wires is disposed so as to surround the copper electric wires having a lower shape retention property than the aluminum electric wires. The bundles electric wires include bent portions formed by bending or curving the bundled electric wires respectively.
