A motor control apparatus includes a current target value computation unit which computes a target value of a current to be passed through a motor; a current detector which detects the current passed through the motor; a command value computation unit which computes a command value to the motor based on a deviation between the current target value computed by the current target value computation unit and the current value detected by the current detector; a PWM control unit and a motor drive circuit which drive the motor based on the command value; and a boosting circuit which boosts a voltage supplied to the motor. A boosting control unit is provided in the motor control apparatus, which judges whether or not the command value computed by the command value computation unit exceeds a predetermined threshold, computes a rate of change of the command value to time, and controls an boosting operation of the boosting circuit based on the judgment result and the rate of change of the command value.
