Abstract

Provided is an electroacoustic converter film including thin film electrodes provided on both surfaces of a polymeric composite piezoelectric body in which piezoelectric body particles are dispersed in a viscoelastic matrix formed of a polymer material that exhibits viscoelasticity at normal temperature, and protective layers formed on the thin film electrodes. The electroacoustic converter film further includes electrode lead-out metal foils laminated on the thin film electrodes, and the electrode lead-out metal foils allows connection to wiring through soldering when electrodes are led out from the thin film electrodes.
