A motor control apparatus includes a target value computation device which computes a target value of a current to be passed through a motor, a current detection device which detects a current passed through the motor, a command value computation device which computes a command value to the motor based on a deviation between the target value and the current value, a motor drive circuit which drives the motor based on the command value, a boosting circuit which boosts a voltage supplied to the motor, a judgment device which judges whether the command value exceeds a predetermined threshold, a rate-of-charge computation device which computes a rate of change of the command value to time, and a boosting control device which controls an boosting operation of the boosting circuit based on a result of the judgment device and the rate of change of the command value.
