PURPOSE:To obtain a high electroconductive heat-resistant copper alloy having excellent repeated bending strength and tensile strength by respectively incorporating specific amounts of Mg, P and one kind among In, Sn, Pb and Sb into the alloy. CONSTITUTION:The copper alloy contains, by weight, 0.02-0.5% Mg, 35-100% P for Mg, 0.01-0.8% Zr, one kind among 0.01-0.5% In, Sn, Pb and Sb and the balance consisting of Cu. Said copper alloy is suitable as the conductor of an electrical wire for wiring in a prior electronic equipment and as the conductor of a cable for an industrial robot. The titled alloy furthermore has the capacity which is effectively usable at the time of using the alloy as about 0.3-0.01mmphi thin diameter conductor accompanied by the miniaturization of an electronic equipment and as a cable for the robot which operates repeatedly.
