An ultrasonic-motor driving apparatus includes an ultrasonic motor, a driving unit, and a characteristic storage. The driving unit is detachable from the ultrasonic motor and has a driving circuit for driving the ultrasonic motor. The characteristic storage provided in the ultrasonic motor stores driving characteristic values of a resonant frequency and a drive voltage signal specific to the ultrasonic motor. The driving circuit drives and controls the ultrasonic motor based on the driving characteristic values stored in the characteristic storage.
