ABSTRACT:
A piezoelectric actuator includes piezoelectric layers. Individual electrodes are formed on an outermost piezoelectric layer and arranged in a row extending along a first direction. Through holes are formed in the outermost piezoelectric layer and arranged substantially in a row extending in the first direction to contact with first end portions of the individual electrodes. The individual electrodes include at least one first individual electrode and at least one second individual electrode. The first individual electrode comprises a first electrode terminal provided at the first end portion, and the second individual electrode comprises a second electrode terminal provided at a second end portion opposite to the first end portion with respect to a second direction perpendicular to the first direction. The second individual electrode has a thickened portion extending from the second electrode terminal towards the first end portion.
