On a driven film (13) forming the upper wall surface (21a) of the pressurizing chamber (21) and the side-chamber (23), a lower electrode (33), a driving member, and an upper electrode (35) are formed in this order. The driving member is composed of an operation section (31p) located over the pressurizing chamber (21), and an extended section (31a) extending from the operation section (31p) to over the side-chamber (23). The side-chamber (23) has a smaller width than the pressurizing chamber (21) in a second direction perpendicular to a first direction in which the side-chamber (23) is located beside the pressurizing chamber (21).

Abstract: A stress relaxing layer L22 composed of MgO is formed on the upper surface of a substrate layer L1 in order to alleviate stress acting on a piezoelectric layer L3, the stress relaxing layer L22 is removed while leaving behind a region D1 where the piezoelectric layer L3 is to be formed, and the single crystal piezoelectric layer L3 is formed on the upper surface of the stress relaxing layer L22. As a result, the stress relaxing layer L22 in a region D2 where the piezoelectric layer L3 is not to be formed is preliminarily removed, the region D1 where the piezoelectric layer L3 is to be formed is reduced in size, and stress acting on the piezoelectric layer L3 attributable to the difference in lattice constant between the stress relaxing layer L22 and the piezoelectric layer L3 and thermal expansion is alleviated, thereby enabling favorable single crystallization of the piezoelectric layer L3.
