ータ。[Claims for Utility Model Registration] (1) A piezoelectric actuator in which a plurality of piezoelectric ceramic plates are stacked so that the polarization directions are alternately different, and a predetermined displacement is obtained by applying a voltage to the piezoelectric actuator, in which adjacent The opposing surfaces of the electrodes of the piezoelectric ceramic plate are bonded to each other with an adhesive layer to form an internal electrode part, and one end of each of the internal electrode parts is connected so that the internal electrode part is alternately electrically connected to the external electrodes on both sides. A groove is provided every other layer in the portion where the internal electrode portion is located, and a groove is provided in every other layer in the portion where each other end of the internal electrode portion is located, one layer offset from the groove on the one end side. A laminated piezoelectric actuator characterized by filling each groove with an insulating material. (2) The laminated piezoelectric actuator according to claim 1, wherein the adhesive layer is made of an epoxy resin having a glass transition point of 100° C. or higher.
