ABSTRACT:
A piezoelectric transformer element includes electrodes formed on a maximum-area of the front surface and rear surface of a long-plate shaped piezoelectric body. A case in which the piezoelectric transformer element is housed includes first lead terminals and second lead terminals. The first lead terminals press the electrodes on the front surface of the piezoelectric transformer element and are electrically connected to the electrodes. The second lead terminals press the electrodes on the rear surface of the piezoelectric transformer element and are electrically connected to the electrodes. The piezoelectric transformer element is held within the case by the first and second lead terminals and ring-shaped elastic bodies in which the piezoelectric transformer element is inserted. Thus, inhibition of vibration of the piezoelectric transformer element is suppressed and energy conversion efficiency of the piezoelectric transformer element is improved.
