ABSTRACT:
A first common electrode is fixed at a predetermined potential. A first piezoelectric layer is laminated on the first common electrode and has a first deformability with respect to a predetermined voltage. A drive electrode is laminated on the first piezoelectric layer, to which a drive signal is supplied externally. A second piezoelectric layer is laminated on the drive electrode and having a second deformability with respect to the predetermined voltage which is larger than the first deformability. A second common electrode is laminated on the second piezoelectric layer and to be fixed at the predetermined potential.
