摘要： PROBLEM TO BE SOLVED: To provide a terminal member of a rail bond and a welding method of the rail bond, capable of reducing quantity of solder used for welding the terminal member of the rail bond, and capable of also efficiently welding the terminal member in a short time.SOLUTION: The terminal member comprises a cylindrical part 2 into which an electric wire 3 of the rail bond is inserted and which press-fits the inserted electric wire and a terminal part 4 provided on the tip side more than the cylindrical part and welded to a welding surface 10a of a rail side part. The terminal part is formed in a band plate shape of extending in the axial direction of the electric wire, and one surface is formed as a cross-sectional circular arc-shaped convex surface having a predetermined radius of curvature R1. The convex surface side of the terminal part faces to the welding surface of the rail, and a radius of curvature R2 in the radial direction on the convex surface side is smaller than the radius of curvature in the radial direction of the welding surface.
