Title: Laminated type piezoelectric actuator
Inventor: KIMURA TASUKE
IPC: H01L41/083
Filed: 1990-03-20
Abstract: PURPOSE:To achieve improvement of dielectric strength characteristic and relaxation of concentration of internal stress by a method wherein an inner electrode excepting a part is drawn in from an outer peripheral surface of an element to be formed, and a dummy part is installed to the periphery. CONSTITUTION:Electrode parts 2a, 2b of which only one parts are exposed to an outer periphery are provided as an inner electrode on a piezoelectric plate 1, and are bonded to outer electrodes 3a, 3b in an exposed part. Since the electrode parts 2a, 2b of the inner electrode are not exposed to the outer periphery of the element excepting the bonded parts, there is no fear of coming in contact with the outer electrodes 3a, 3b of reverse polarity, and there is no necessity for installing an electric insulation layer. Therefore, cost can be steeply reduced. Further, since the electrode surfaces 2a, 2b of the inner electrode are not exposed to the outer periphery of the element, leak current between electrodes of reverse polarities can be prevented, and a dielectric strength characteristic is improved. Further, since dummy parts 2c, 2d are formed in the outer peripheral part wherein the electrode parts 2a, 2b on the piezoelectric plate 1 are not installed, pressure and internal stress in manufacturing are relaxed with the dummy parts 2c, 2d, and a crack can be prevented from occurring.
