Abstract
A thin-film piezoelectric material element includes a laminated structure part having a lower electrode film, a piezoelectric material film laminated on the lower electrode film and an upper electrode film laminated on the piezoelectric material film. The thin-film piezoelectric material element includes a surface layer insulating film disposed on side surfaces of the laminated structure part, a first top surface of the upper electrode film and a second top surface of the lower electrode film, and has a first through hole formed on a first top disposed part and a second through hole formed on a second top disposed part. Further, the surface layer insulating film has an upper electrode pad being in directly contact with a first inside exposed surface and a lower electrode pad being in directly contact with a second inside exposed surface.
