Document Type and Number:
Japanese Patent JP3045531
Kind Code:
B2
Abstract:
A laminate displacement device comprises a laminate body having a plurality of thin plates made of an electromechanical converting material and a plurality of internal electrodes made of conductive material superposed on each other. The internal electrodes are used for every other electrode alternately as electrodes of first and second conductivity type, respectively. A first insulating layer is formed on one side surface of the laminate body so that the internal electrodes used for the electrodes of first conductivity type are exposed. Further a second insulating layer is formed on another side surface of the laminate body so that the internal electrodes used for the electrodes of second conductivity type are exposed. A pair of external electrodes are formed on the first and second insulating layers, which bridge the internal electrodes used as the electrodes of first and second conductivity type, respectively. The insulating layers are made of a crystalline inorganic material containing Pb converted into PbO of 5.0 to 45.0 wt. %.
