Abstract
A reliable piezoelectric actuator whose warpage is prevented and of which electrodes are prevented from peeling off, and an ink-jet print head including the piezoelectric actuator are manufactured. A piezoelectric sheet having individual electrodes formed thereon and another piezoelectric sheet having common electrodes formed thereon are stacked alternately on top of each other in layers, with an insulating sheet having surface electrodes placed on the top. Each piezoelectric sheet has through holes. The through holes are formed such that through holes adjacent in a direction parallel to the alignment of the individual electrodes are not aligned.
