Abstract
A copper alloy wire rod has a chemical composition comprising Ag: 0.1 to 6.0 mass % and P: 0 to 20 mass ppm, the balance being copper with inevitable impurities. In a cross section parallel to a longitudinal direction of the wire rod, a number density of second phase particles each having an aspect ratio of greater than or equal to 1.5 and a size in a direction perpendicular to the longitudinal direction of the wire rod of less than or equal to 200 nm is greater than or equal to 1.4 particles/μm.
