    摘要: To provide a piezoelectric actuator that is small in size, large in displacement, high in rigidity, excellent in controllability, and excellent in stability, the present invention provides a piezoelectric actuator, including: a first piezoelectric member that is bent and displaced in a thickness direction; and a second piezoelectric member that is bent and displaced in a direction opposite to the first piezoelectric member. In the piezoelectric actuator, the first piezoelectric member and the second piezoelectric member are stacked on each other in the thickness direction of the first piezoelectric member and the second piezoelectric member, and the center portion in the longitudinal direction of the first piezoelectric member and the center portion in the longitudinal direction of the second piezoelectric member, or both ends of the first piezoelectric member and both ends of the second piezoelectric member are fixed to each other.

    摘要: Pluralities of electrode groups are formed on one face of a piezoelectric element, and a common electrode is formed on another face. The common electrode is connected to a booster circuit for boosting a voltage signal obtained from an amplifier circuit. The pluralities of electrode groups are connected to selection circuits for switching a signal path of a signal output from here.
