In a piezoelectric bimorph element made of two piezoelectric plates having electrodes formed on both sides and a metal plate bonded together in a sandwich pattern, the piezoelectric bimorph element is bonded to a metal plate among the electrodes of the two piezoelectric plates. A full-surface electrode is formed on each surface, and a first electrode for bending in the direction of the longitudinal force and a two-part electrode for applying torsional displacement in a direction orthogonal to the direction of the longitudinal force are formed on the other surface, facing the full-surface electrode. A piezoelectric bimorph element characterized in that it is formed with two layers. 2 The two piezoelectric plates are divided in the thickness direction, one of the two divided electrode parts is polarized to have opposite polarity, and the polarity of the polarization of the surface of the two piezoelectric plates to be bonded to the metal plate is changed. A piezoelectric bimorph element according to claim 1 of the utility model registration claim.
