ABSTRACT:
There is herein disclosed a piezoelectric composite transducer comprising a plurality of piezoelectric ceramic poles. The plurality of piezoelectric ceramic poles are arranged two-dimensionally so as to form spaces therebetween. Organic films are disposed on both end surfaces of the plurality of piezoelectric ceramic poles so that the spaces forms hollow portions. The hollow portions causes making small its acoustic impedance up to a value close to the acoustic impedance of water or a human body.
