PROBLEM TO BE SOLVED: To provide a copper alloy showing a good balance between a high strength and a high conductivity. SOLUTION: The copper alloy contains 0.01-4.0 mass% Fe, wherein≤80% of the added Fe is left in an extract obtained by dissolving only a matrix of the copper alloy and separating and extracting oxides, crystallized products and precipitates within the copper alloy using a mesh having a sieve opening 0.1μm. As alloy components other than Fe, one or more elements chosen from 0.01-0.1 mass% P, 0.01-1.0 mass% Zn and 0.01-0.5 mass% Sn are added, either alone or in combination. COPYRIGHT: (C)2004,JPO
