ABSTRACT:
A method for manufacturing piezoelectric actuator which includes a piezoelectric layer formed of a piezoelectric ceramics material and having a drive area, a first electrode and a second electrode arranged on both surfaces of the piezoelectric material layer respectively each at portion corresponding to the drive area, and a ceramics layer formed of a ceramics material and stacked to face the surface of the piezoelectric material layer on which the first electrode is arranged, the method including: forming a stacked body which includes the piezoelectric material layer, the ceramics layer, and the first electrode, and sintering the stacked body; forming the second electrode on the other surface, of the piezoelectric material layer after the sintering, not facing the ceramics layer; and forming elastic layers having a lower coefficient of elasticity than that of the piezoelectric material layer on both surfaces respectively of the stacked body after the sintering.
