PROBLEM TO BE SOLVED: To provide a copper alloy for a terminal/a connector jointly having an excellent electric conductivity compared with that of the conventional material for a terminal/a connector while securing its high strength, spring properties and migration resistance. SOLUTION: The copper alloy has a composition comprising, by mass, 0.1 to 0.5% Fe, 0.2 to 1.0% Ni, 0.03 to 0.2% P, 0.02 to 0.1% Si, 0.01 to 1.0% Sn and 0.1 to 1.0% Zn, and the balance Cu, and in which the ratio between the total mass of the Fe and the Ni and the total mass of the P and the Si, (Fe+Ni)/(P+Si)=3 to 10.
