A copper alloy wire is composed of a precipitation-hardened copper alloy containing Co, P and Sn, and can be produced by the cold working of a continuously casted wire produced by a continuous casting-rolling method or a continuous casting method. The copper alloy wire has a chemical composition comprising 0.20 to 0.35 mass% inclusive of Co, more than 0.095 mass% and 0.15 mass% or less of P and 0.01 to 0.5 mass% inclusive of Sn, with the remainder made up by Cu and unavoidable impurities. |
