Abstract
A piezoelectric transducer has groups of a first part and second part therebetween. Thin piezoelectric ceramic layers in groups and thick piezoelectric ceramic layers in the second part are polarized in the direction of thickness A or B. All of electrodes are layers, and each electrode is provided between the piezoelectric ceramic layers. A step-up output voltage is generated between the piezoelectric ceramic layers of the second part by longitudinal vibration of the piezoelectric ceramic layers of the groups.
