が求められている。2. Description of the Related Art In recent years, as the performance of personal computers and peripheral devices has increased, the interface cables used therein have also been required to have higher performance and higher quality. The conductor used for the interface cable is required to have excellent bending characteristics in an environment in which the cable is used, and to be capable of processing the terminal such that the conductor strands are not easily separated when the terminal is processed. Usually, hard or soft materials of copper and copper alloy wires are used for the conductor. The hard material of the copper alloy wire has the advantage of being excellent in bending characteristics due to its high strength, but has the disadvantage of poor end workability due to insufficient elongation. On the other hand, the soft material has a large elongation and is excellent in end workability, but has a disadvantage that the bending resistance is small due to insufficient strength. Therefore, as a conductor used for an interface cable, a conductive ultrafine alloy wire having a high conductivity and a semi-hard material having both of these characteristics is required.
