A control apparatus of an ultrasonic motor, comprises a driving wave number determining means for determining a driving wave number based on the targeted displacement of a driven object driven by the ultrasonic motor, a normative driving wave generating means for generating continuously normative driving waves in the number of times determined at the driving wave number determining means, inserted an interval determined based on the targeted velocity of the driven object, every at least one cycle of the normative driving waves, and a driving wave generating means for generating driving waves having the predetermined frequency and the predetermined amplitude based on the normative driving waves generated at the normative driving wave generating means.
