Abstract
A copper alloy for an electronic and electric device includes: Mg in a range of 0.1 mass % or more and less than 0.5 mass %; and a Cu balance including inevitable impurities, wherein a graph, in which a vertical axis is dσt/dεt and a horizontal axis is a true strain εt, dσt/dεt being defined by a true stress σt and the true strain εt, obtained in a tensile test of the copper alloy, has a strained region that has a positive slope of dσt/dεt.
