PROBLEM TO BE SOLVED: To provide a method for reducing drawing resistance of deformed wire drawing in the cold working process in the manufacture of a deposit strengthened copper alloy trolley wire. SOLUTION: This manufacturing method of the deposit strengthened copper alloy trolley wire has at least (A) a solution treatment process, (B) a cold working process, and (C) an aging heat treatment process, and is characterized in that at least skinning, round wire drawing and the deformed wire drawing are performed in this order in the cold working process, and a further round wire drawing is desirably performed before the skinning process. This manufacturing method can relatively reduce the drawing resistance in the deformed wire drawing work because the deformed wire drawing is performed after conditioning the surface of rough drawn wire suitable for wire drawing by the round wire drawing providing relatively small drawing resistance.
