Abstract

See full text

Provided are an ultrasonic transducer having a state monitoring function, and an ultrasonic cleaning device using the same. The ultrasonic transducer having a state monitoring function is a Langevin ultrasonic transducer for use in an ultrasonic cleaning device configured to clean an object to be cleaned via cleaning liquid to which ultrasonic vibrations are applied, the ultrasonic transducer having a state monitoring function including a plurality of piezoelectric elements, which are arranged to be stacked on each other, and are expandable and contractable in a direction of the stacking, a part of the plurality of piezoelectric elements serving as a vibration exciting piezoelectric element configured to expand and contract by being applied with an AC voltage, another part of the plurality of piezoelectric elements serving as a state monitoring piezoelectric element configured to output a state monitoring voltage by the expansion and contraction of the vibration exciting piezoelectric element.
