The invention attenuates noise caused by pulsation of brake fluid generated during driving of a pump. A pulsation damping section (80) provided in a pump device is provided with a fixing member (86) that divides a housing chamber (58) into an upstream region and a downstream region, and the fixing member (86) has a hole (83 b) in the center. The upstream region is provided with an upstream movable member (84), an inflow opening side damper portion (81 a) for accommodating an inflow opening side elastic body (92), and a fixed member side damper portion (81 c) for accommodating a fixed member side elastic body (91). The downstream region is provided with a downstream movable member (85) and an outflow opening side damper (81 b) for accommodating an outflow opening side elastic body (96). The upstream movable member (84) is provided with a through hole (84 b), the through hole (84 b) is provided with a seat (84 d) that can be closed by a valve member (94), and the valve member (94) is configured so as to be capable of abutting against the cylindrical portion (86 d) when the upstream movable member (84) moves.
