Abstract
An ink impermeable and electrically insulative adhesive sheet is pasted to the lower surface of a piezoelectric actuator, which is constructed by laminating alternately a piezoelectric sheet with individual electrodes and a piezoelectric sheet with a common electrode. Then, the piezoelectric actuator is bonded to a cavity plate by the aid of the adhesive sheet such that the individual electrodes of the piezoelectric actuator are aligned with pressure chambers of the cavity plate. In this construction, electrical insulation between the piezoelectric sheets is not damaged by ink in the pressure chambers of the cavity plate.
