ABSTRACT:
A head for an ink-jet printer includes a plurality of ink chambers arranged in parallel on a plane, a plurality of nozzles communicated with each of the chambers, and a piezoelectric element. The piezoelectric element has a laminated structure in which at least one piezoelectric layer and at least two electrode layers sandwiching the piezoelectric layer are laminated, and is attached to the chambers so as to overlie the chambers with the layers being in parallel to the plane of arrangement of the chambers. The piezoelectric element includes a plurality of pressure portions and a plurality of slits. The slits face the chambers and deepen in a direction perpendicular to the plane of arrangement of the chamber so as to divide the pressure portions from other portion or the piezoelectric element such that each of the pressure portions attaches to each of the chambers at an area defined by the slits and that each of the pressure portions includes the laminated structure. Each of the pressure portion presses each of the chambers at the attaching area by an expansion due to a piezoelectric effect when an electric voltage is applied across the electrode layers in each of the pressure portions.
