Abstract: To provide an ultrasonic generator capable of detecting any of a state operated without a water load, abnormality of an ultrasonic transducer and abnormality of a cleaning bath. The ultrasonic generator according to the present invention includes a signal source 9 for generating a signal having at least one of frequencies of f1, f2 and f3, a matching circuit 17 for matching the signal generated from the signal source, an ultrasonic transducer 2 to which the signal matched by the matching circuit is input, a detection circuit 10 for detecting the voltage value and current value of the signal input to the ultrasonic transducer, an impedance computing unit 11 for computing the impedance to the signal using the voltage value and current value detected by the detection circuit, and a determination part 13 for determining abnormality of the cleaning bath or the ultrasonic transducer by comparing the impedance to the signal computed by the impedance computing unit with a previously-set threshold for detecting an impedance abnormality.
