In FIG. 14, a drive circuit 23 generates and amplifies an ultrasonic signal from the ultrasonic transducer and supplies the amplified ultrasonic signal to the handpiece 4. The phase difference between the voltage and the current of the ultrasonic signal supplied to the ultrasonic transducer is obtained.
