Abstract
An ultrasonic treating apparatus includes an inpedance detection unit for detecting the impedance of an ultrasonic vibration element for transmitting ultrasonic vibrations and a determining unit for determining whether the ultrasonic vibration element is good or not. If the ultrasonic vibration element is found not to be good, then a control unit inhibits ultrasonic vibrations from being generated from the ultrasonic vibration element. It is thus possible to prevent any breakage of the apparatus.
