A railway wheel includes: a wheel (10) including a plate portion (13); and a brake disc (1) including a circular plate portion (2) whose front face (2a) side is a sliding surface, and a plurality of fin portions (3) which are radially projected on a back face (2b) of a circular plate portion (2), wherein two of the brake discs (1) interpose the plate portion (13) of the wheel (10) with each of sliding surfaces thereof facing outwardly, and are fastened in a region within the sliding surface. Regarding an area of a section crossing a space formed between the brake disc (1) and the wheel (10) along a circumferential direction, a minimum section portion in which the sectional area is minimum is present in a region formed by an outer peripheral surface (2c) of the circular plate portion (2) and an inner peripheral surface (2c) of the rim portion (12), and the outer peripheral surface (2c) of the circular plate portion (2) follows the inner peripheral surface (12b) of the rim portion (12) in a region extending to the outer side from the minimum section portion. The railway wheel includes a brake disc which has a simple shape and an excellent productivity, and can effectively reduce aerodynamic sound during high speed travelling.
