A method for driving an ultrasonic motor having an actuator section includes: a step of starting the ultrasonic motor by applying an AC voltage with a first frequency to the actuator section; a voltage detection step of detecting a voltage generated at the actuator section while lowering a driving frequency from the first frequency to a second frequency at which the ultrasonic motor stops; a starting step of starting the ultrasonic motor with a third frequency; and a driving step of changing the driving frequency from the third frequency to a lower frequency such that the driving frequency has a value within an operation frequency range, wherein the operation frequency range is within a range on a higher frequency side than the driving frequency at which a maximum voltage is detected in the voltage detection step.
