摘要： PROBLEM TO BE SOLVED: To provide a disc brake which is improved in productivity.SOLUTION: An outer peripheral side corner part of an opening side end part 17 of a piston 8 is formed by a convex-shaped curved surface 18 smoothly continuing to an outer peripheral surface 12. Thereby, when forming a coating film 13 at least on the outer peripheral surface 12 of the piston 8 by an electrolytic plating method, current density distribution at the time of electric conduction can be made uniform. Compared with a conventional piston of a disc brake in which a chamfer part is formed by C-chamfering on the outer peripheral side corner part on the opening side end part, power supply time at the time of electrolytic plating can be greatly shortened. As a result, productivity of disc brakes can be enhanced.
