PROBLEM TO BE SOLVED: To provide a plated copper wire that is excellent in heat resistance and shows resistance to corrosion, and a method for manufacturing the same. SOLUTION: The plated copper wire has a plurality of plating layers on a surface of a Cu substrate, in which a surface part thereof is composed of a Sn-based plating layer 4 made of Sn or a Sn alloy and having an average thickness of 0.05-1.5 μm, and a Sn-Ag coating layer 5 formed on the Sn-based plating layer 4, and having a hardness of 10-20 Hv and an average thickness of 0.05-0.5 μm. The Sn-Ag coating layer 5 contains Sn particles 11 and Ag<SB>3</SB>Sn particles 12 having average particle sizes of 1-10 μm and 10-100 nm, respectively. COPYRIGHT: (C)2011,JPO&INPIT
