An oil pressure control device for supplying oil pressure by rotating a hydraulic pump, by means of a motor, comprises an oil pressure sensor; a speed instruction operation unit for outputting a speed instruction value, based on a difference between an oil pressure determination value from the oil pressure sensor and an oil pressure instruction value; a torque instruction value operation unit for calculating a torque instruction value, based on a difference between a speed determination value and the speed instruction value; and a current control unit for controlling a current of the motor, based on the torque instruction value, and adds the load variation compensation speed outputted from the load variation compensation unit and the speed instruction value.
