摘要：
Piezoelectric elements constituted by lower electrodes, piezoelectric layers, and an upper electrode are extended from positions corresponding to openings of pressure chambers to outer positions beyond opening edges of the pressure chambers. The piezoelectric layers have exposure portions on the extended portions and the exposure portions of the piezoelectric layers are covered by an adhesive between an actuator unit and a sealing plate.
