摘要： A wing type ultrasonic transducer is free from a reduction in the output power and has one ultrasonic generator. This ultrasonic generator has piezoelectric ceramic materials with two countermasses respectively coupled to the outside ends of the piezoelectric ceramic materials. A rod-like resonator is coaxially coupled to the outside end of each of the countermasses and is used to emit ultrasonic waves to a liquid in a radial direction. An immersible housing covers the ultrasonic generator so as to accomplish a water tightness of the ultrasonic generator. The rod-like resonator may be a solid resonator or hollow resonator. In addition, the rod-like resonator is integral times as long as a half-wavelength (&lgr;/2) at an operating resonant frequency.
