Abstract
An object is to provide a laminated piezoelectric element capable of preventing a short circuit between adjacent piezoelectric films and an electroacoustic transducer using the laminated piezoelectric element. The object is solved by laminating a plurality of layers of piezoelectric films polarized in a thickness direction, in which a piezoelectric layer is interposed between two thin film electrodes, and causing polarization directions of the adjacent piezoelectric films to be opposite to each other.
