Abstract

The present invention relates to a Cu-Ni-Sn-P-based copper alloy sheet having a specific composition, where the X-ray diffraction intensity ratio I(200)/I(220) in the sheet surface is set to be a given value or less and at the same time, anisotropy in the stress relaxation resistance characteristic is reduced by fining the grain size. The Cu-Ni-Sn-P-based copper alloy sheet of the present invention is excellent in the properties required for a terminal or connector and further satisfies the stress relaxation resistance characteristic in the direction orthogonal to the rolling direction.
