Abstract: A piezoelectric ceramic transformer has a general shape of a disk and is divided in a thickness direction into a generating part and a driving part or symmetrically into a generating part, a driving part and another generating part or into a driving part, a generating part and another driving part. Each of the parts has a layering structure wherein layers are polarized alternately in the thickness direction, and inner electrodes are drawn around from side end faces to main surfaces through outer electrodes and electronic terminals are led out from locations in the proximity of the centers of main surfaces which coincide with nodes of vibrations. In operation, a basic mode of radial direction expansion vibrations is utilized. When a voltage is applied to a driving side electronic terminal in a frequency of a vibration basic mode, the driving part vibrates in a kr mode which relies upon electromechanical coupling coefficient kr.
