PROBLEM TO BE SOLVED: To perform washing without taking time by forming timing of performing an efficient operation for all ultrasonic vibrators in the case of driving the plurality of ultrasonic vibrators with drive circuits fewer than those. SOLUTION: In the apparatus of driving the ultrasonic vibrator in the ultrasonic washing machine, the plurality of ultrasonic vibrators for imparting ultrasonic vibrations to washing liquid and the drive circuits fewer than the ultrasonic vibrators for driving the ultrasonic vibrators are provided, and the drive circuit can set an optional frequency between the upper limit and lower limit of dispersion of a frequency capable of the most efficient drive for each of the plurality of ultrasonic vibrators, and can switch the set frequency and the center frequency of the dispersion further.
