A laminated piezoelectric actuator includes piezoelectric plates, and inner electrode layers composed of an electrode material. The piezoelectric plates and the inner electrode layers are laminated alternately. The electrode material includes a metallic component, and an electrically conductive oxide. When the electrically conductive oxide, in which the oxygen ions works as carriers, is added to the electrode material, oxygen is supplied into the operating piezoelectric plates from the inner electrode layers. As a result, the piezoelectric plates are inhibited from degrading. |
