Original Abstract Submitted
A piezoelectric element includes a substrate, a lower electrode arranged on the substrate, a piezoelectric film arranged on the lower electrode, and an upper electrode arranged on the piezoelectric film. Membrane portions are configured by the lower electrode, the piezoelectric film, and the upper electrode, and supported in a cantilever manner on the substrate, due to a recess formed in the substrate and a through hole penetrating the lower electrode, the piezoelectric film, and the upper electrode. At least two of the membrane portions have resonance frequencies different from each other.
