Abstract
The ink jet printer includes a pressure chamber plate having a plurality of pressure chambers 20 separated by bulkheads, and a piezoelectric member having drive sections arranged opposite to the pressure chambers via a vibrating plate. The drive sections are separated from each other by parallel extending grooves. The piezoelectric member has inner electrodes 32 embedded therein and exposed to the side surfaces of the drive sections. The exposed portions of the inner electrodes are covered by insulating members, so that no short circuit is caused between the inner electrodes provided in the piezoelectric member.
