PROBLEM TO BE SOLVED: To provide a copper alloy which has superior bendability, and is suitable for a connector and a terminal material for electric or electronic equipment with high tensile strength, for instance, a connector, a switch, a terminal material and a relay which are mounted in automobiles. SOLUTION: The copper alloy is composed of Ni and/or Si, at least one or more substances selected from B, Al, As, Hf, Zr, Cr, Ti, C, Fe, P, In, Sb, Mn, Ta, V, S, O, N, misch metal (MM), Co and Be, and the balance of Cu and unavoidable impurities. This copper alloy has a precipitate X composed of Ni and Si and a precipitate Y composed of Ni and/or Si and at least one substance selected from B, Al, As, Hf, Zr, Cr, Ti, C, Fe, P, In, Sb, Mn, Ta, V, S, O, N, misch metal (MM), Co and Be, and the particle size of the precipitate Y is 0.01 to 2μm.
