ABSTRACT:
A laminated piezoelectric device and method for manufacturing the device, wherein a large number of thin sheets of piezoelectric ceramic are disposed one on another via electrode films formed on the surfaces of the sheets of piezoelectric ceramic. Electrode films of the piezoelectric elements then are connected to each other with electric conductors to form a one-piece laminated piezoelectric device. Polarization of the whole of a large number of piezoelectric elements then is performed at one time.
