イモルフ。In a piezoelectric bimorph, which is made by laminating a thin piezoelectric element to which a voltage is applied in the same direction as the polarization axis direction and a thick piezoelectric element to which a voltage is applied in the opposite direction to the polarization axis direction, the thickness is the same as that of one piezoelectric element. A piezoelectric bimorph characterized in that a correction plate having the same coefficient of thermal expansion is bonded to the surface of the other piezoelectric element.
