Abstract

PURPOSE: A thin piezo-electric porcelain having been polarized in the thickness direction is overlapped upon another one with polarization directions made opposite each other, and every other electrode of this lap is connected in common to be a low-voltage terminal, so that excellent transformation will be achieved even at the frequency except one near a natural oscillation frequency.
