An electric pump device of an aspect of the invention includes a state determination unit and a gain adjusting unit. The state determination unit determines whether or not the electric pump device is in a stable state where a required oil pressure is supplied to a hydraulic operating device by maintaining a rotation state of a motor. The gain adjusting unit adjusts a gain for a current feedback control so as to reduce responsiveness of the current feedback control when the state determination unit determines that the electric pump device is in the stable state.
