PROBLEM TO BE SOLVED: To provide an ultrasonic cleaning machine which is capable of properly washing a material to be washed even if the output of an ultrasonic vibrator used in the ultrasonic cleaning machine has a variation. SOLUTION: The ultrasonic cleaning machine is provided with the ultrasonic vibrator 30 to impart ultrasonic vibration to a washing liquid and a driving circuit 34 to drive the ultrasonic vibrator 30. The ultrasonic cleaning machine is further provided with a current detection circuit 46 to detect the current value flowing through the ultrasonic vibrator 30 and a superordinate substrate 32 to control the driving circuit 34 so as to change the driving time of the ultrasonic vibrator 30 when washed, so that the ultrasonic generation rate at the time of washing becomes a predetermined volume based on the current value detected by the current detection means 46 in a predetermined timing.
