A cable is provided with a cable core including one or more electric wires, a shield layer provided to cover around the cable core and composed of a laterally wound shield formed by winding metal wire strands helically, and a sheath provided to cover around the shield layer. The metal wire strands are semi-hard copper alloy wires, and P/PD, which is the ratio of the winding pitch P in the laterally wound shield to the pitch diameter PD of the shield layer, is less than 9.9.

Cable

A method for manufacturing a conductive wire includes conducting a continuous casting of a conductive alloy material at a casting rate of not less than 40 mm/min and not more than 200 mm/min to form a conductive wire with a primary diameter, the conductive alloy material containing not more than 1.0 mass % of an added metal element, reducing a diameter of the conductive wire with the primary diameter to form a conductive wire with a secondary diameter, heat treating the conductive wire with the secondary diameter so that tensile strength thereof is reduced to not less than 90% and less than 100% of tensile strength before the heat treating, and reducing a diameter of the conductive wire with the secondary diameter and the reduced tensile strength to generate a logarithmic strain of 7.8 to 12.0 therein to form a conductive wire with a tertiary diameter.
