To provide a contact wire with high hardness in the central part.SOLUTION: A contact wire is composed of a copper alloy comprising tin of at least 0.15 mass% and at most 0.60 mass%, featuring a cross section with a central part and an outer peripheral part. The central part is the region with the orientation ratio of the crystal's 111 plane, determined by X-ray diffraction, being 70% or more. The outer peripheral part is the region with the orientation ratio being less than 70%.SELECTED DRAWING: Figure 2
