摘要：
{Problems} To provide, at low cost, a copper alloy wire that is excellent in a balance between high physical strength and favorable elongation, that is excellent in coil characteristics (service life of the coil and coil formability), which is obtained by using the copper alloy wire, and that is used, for example, in magnet wires.
{Means to solve} A copper alloy wire containing 0.1 to 4 mass% of Ag, with the balance being Cu and unavoidable impurities, wherein an area ratio of grains having orientation is 30% or more of the entire measurement area, when the transverse cross-section of the wire is observed from the axis direction by the EBSD method; and a method of producing thereof.
