Abstract: A curved piezoelectric element comprises at least one piezoelectric piece of sheet formed into a wave shape which deforms when a voltage is applied thereto. The wave shape of the piezoelectric piece comprises essentially at least two half-waves connected contiguously and consecutively in one body.
