Two sets of bend elements are attached together via shims, and the piezoelectric element and electrostrictive element of each bent element are electrically connected to each other so as to cancel changes in capacitance due to temperature changes. An electromechanical transducer element characterized by being wired in series and connected to an alternating current power source via a diode so that an alternating voltage is alternately applied to two sets of bend elements.
