A railway vehicle brake disc which can reduce aerodynamic sound raised high speed running, improve cooling performance during braking, and improve durability comprises a donut-shaped disc section having a sliding surface on a front surface side, a plurality of fin sections, each convexly provided in a rear surface of the disc section in a radial pattern, and a bolt hole passing through the disc section and the fin section. The disc section is mounted on a wheel in a state where the fin sections contact a plate section of the wheel using a bolt inserted into the bolt hole. The fin section has a groove formed along a circumferential direction in at least one of an area on an inner peripheral side and an area on an outer peripheral side of the bolt hole when viewed in a radial direction of the disc section.
