Abstract
The fatigue resistance characteristics, particularly, fatigue resistance characteristics after retention at 150° C. for 1000 hours are improved while maintaining the characteristics in the related art. Provided is a copper alloy sheet having a composition containing 0.2% by mass to 1.2% by mass of Mg, and 0.001% by mass to 0.2% by mass of P, the balance being Cu and unavoidable impurities. When X-ray diffraction intensity of a {110} crystal plane is set as I{110}, and X-ray diffraction intensity of {110} crystal plane of a pure copper standard powder is set as I{110}, a surface crystal orientation of the copper alloy sheet satisfies a relation of 4.0≦I{110}/I{110}≦6.0.
