IPC: H02N2/00
Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a laminated piezoelectric actuator which can prevent the deterioration of its internal electrodes and has a long service life. SOLUTION: At the time of manufacturing this laminated piezoelectric actuator constituted by alternately laminating a piezoelectric material 105 and the internal electrodes 101a and 103a upon another, the electrodes 101a and 103a are first formed on the material 105. The portions of the electrodes 101a and 103a which are not connected to external electrodes are prevented from being exposed on the side face A of this actuator by making the area of one internal electrode smaller than that of one layer of the material 105. Consequently, the deterioration of the internal electrodes 101a and 103a can be prevented, because the electrodes 101a and 103a are prevented from coming into contact with the outside air. In addition, the surface of this actuator crossing the displacing direction at right angles is coated with a resin having Shore hardness of >=D20.
