Beschreibung
Zusammenfassung:	A copper alloy wire rod containing Ag: 0.5 wt % or more and 6 wt % or less and the balance including inevitable impurities and Cu, in which, on a cross section parallel to a longitudinal direction of the copper alloy wire rod, within a range observed with a visual field of 1.7 μm in a direction perpendicular to the longitudinal direction and 2.3 μm in a direction parallel to the longitudinal direction, the copper alloy wire rod has at least one rectangular range that is a rectangular range having a width perpendicular to the longitudinal direction of 0.2 μm and a length parallel to the longitudinal direction of 2.3 μm and entirely includes five or more second phase particles containing Ag and having a maximum length in the longitudinal direction of less than 300 nm.
