<p>A conductor (2) of plug, socket or connector is provided. The substrate of the conductor (2) is steel and the conductor is obtained by plating a coating of Ni on the substrate, and then plating Cu on the outer surface of the substrate by electrolyzing or electrodepositing with using the substrate as the cathode. Alternatively, the substrate of the conductor (2) is stainless steel, and the conductor (2) is obtained by cladding Cu directly on the columnar stainless steel substrate.</p> |
