Abstract (en)
Provided is a copper alloy wire rod superior in the balance of the strength, the electric conductivity and the drawability. A copper alloy wire rod comprises an alloy composition including 1.0% by mass or more and 6.0% by mass or less of Ag, a remainder being Cu and inevitable impurities, in which, for a peak intensity I(111) of 111 diffraction, a peak intensity I(200) of 200 diffraction, a peak intensity I(220) of 220 diffraction and a peak intensity I(311) of 311 diffraction obtained by X-ray diffraction analysis of a surface, a peak intensity ratio of a total intensity of the peak intensity I(111), the peak intensity I(200) and the peak intensity I(311) relative to the peak intensity I(220) ((the peak intensity I(111) + the peak intensity I(220) + the peak intensity I(311)) / the peak intensity I(220)) is 1.20 or more and 3.00 or less.
