PROBLEM TO BE SOLVED: To provide a trolley cable suitable for ultra high speed of a high-speed railway vehicle, and an overhead wiring including the same.SOLUTION: A trolley cable comprises a copper alloy wire formed of copper alloy which contains exceeding 0.4 mass% and 0.6 mass% or less of tin, and exceeding 0 mass% and 0.1 mass % or less of indium, and in which the remainder comprises copper and an inevitable foreign matter. When a nominal cross section of the copper alloy wire is 170 mm, tension strength is 453 MPa or more, conductor resistance is 0.1410 Ω/km or less, and there is provided vibration fatigue resistance characteristic that vibration frequency is 10,000,000 times or more when vibrating in a condition of adding load tensile force of 27.0kN and load strain of 500μ.SELECTED DRAWING: Figure 1
