A disc brake (1) for allowing a piston (9) in a cylinder (13) to press friction pads (5, 6) against a rotor (3) by means of an oil pressure supplied to a caliper body (7), wherein an electric oil pressure generator (15) is incorporated in the caliper body (7) with a solid element capable of controlling electrically an expansion/contraction operation used as a drive source and is connected to the cylinder (13) via an oil passage (29) formed in the caliper body (7), thereby eliminating the need of an oil pressure pipeline between a cylinder on the caliper body and the electric oil pressure generator and enhancing the operational accuracy and maintainability of the disc brake.
