<p>Provided is a composite electric wire, which is intended to realize a light weight and improve a mechanical strength at the same time and which is enabled to improve the reliability by avoiding the problem of oxide coating or electric erosion so that the electric wire may be easily handled for use as a car-mounted wire harness. The composite electric wire comprises an electric wire body (W) composed of center conductors (CU) and outer-layer conductors (AL) arranged to extend in a Z-direction along the outer circumferences of the center conductors (CU) and to enclose the center conductors (CU). In the electric wire body (W), the center conductors (CU) composed of copper element wires (10) of a (1+ 6) number are sectionally positioned at the center portion of the electric wire body (W) in an X-Y plane, and the outer-layer conductors (AL) composed of twelve copper-coated aluminum element wires (20) are positioned in the outer circumference portion arranged around the center portion of the X-Y plane. Moreover, the outer-layer conductors (AL) make contact at their outer circumferences with the outer circumferences of the center conductors (CU), thereby to make their electric connections.</p> |
