Abstract
A copper alloy sheet has a chemical composition containing 0.7 to 4.0 wt % of Ni, 0.2 to 1.5 wt % of Si, and the balance being copper and unavoidable impurities, the copper alloy sheet having a crystal orientation which satisfies I{200}/I{200}≥1.0, assuming that the intensity of X-ray diffraction on the {200} crystal plane on the surface of the copper alloy sheet is I{200} and that the intensity of X-ray diffraction on the {200} crystal plane of the standard powder of pure copper is I{200}, and which satisfies I{200}/I{422}≥15, assuming that the intensity of X-ray diffraction on the {422} crystal plane on the surface of the copper alloy sheet is I{422}.
