Abstract
A transducer that converts electrical energy to mechanical energy, the transducer includes a dielectric layer; a first electrode that is provided on one surface of the dielectric layer; and a second electrode that is provided on another surface of the dielectric layer. At least one of the first electrode and the second electrode becomes an insulator, before the dielectric layer suffers insulation breakdown by voltage that is applied between the first electrode and the second electrode.
