A hydraulic pump (1) comprising an actuator (2) and a pump unit (3). The pump unit (3) comprises a cylinder (30) and a piston (40) that reciprocally moves along an axial direction (DL). The actuator (2) comprises: a cylindrical coil body (10) arranged coaxially with the cylinder (30) in the axial direction (DL); and a movable body (20) coupled to the piston (40), arranged so as to overlap the cylindrical coil body (10) when viewed in the radial direction along the radial direction (DR), and being reciprocally movable along the axial direction (DL) relative to the cylindrical coil body (10). The movable body (20) is driven towards both sides in the axial direction (DL) by magnetic flux generated from the cylindrical coil body (10).
