層圧電アクチユエータ素子。[Claims for Utility Model Registration] Includes a laminated sintered body in which sheet-like piezoelectric ceramic members and internal electrode conductor layers are alternately laminated, and the internal electrode conductor is exposed on a pair of opposing sides of the laminated sintered body. One end surface of the layers is alternately insulated on the pair of side surfaces, and the other end of the internal electrode conductor layer that is not insulated is connected to an external electrode conductor layer provided for each side surface, and the layer is laminated. In a laminated piezoelectric actuator element that has a piezoelectric layer made of only a piezoelectric ceramic member approximately in the center of the sintered body, and a lead wire is connected to an external electrode conductor layer on this piezoelectric layer, soldering of the lead wire is required. The external electrode conductor layer at the attachment part is
A laminated piezoelectric actuator element characterized in that it is connected to an external electrode conductor layer in other parts through a narrow constricted part.
