GESCHICHTETE KERAMIKANORDNUNG UND VERFAHREN ZU DEREN HERSTELLUNG.

摘要

The principal object of the present invention is to provide a laminated ceramic device that can prevent concentration of stress due to unevenly distributed strain caused by application of an electric field. According to the invention, there is provided a laminated ceramic device comprising a plurality of ceramic sheets that can be subjected to electrostrictive force, a first and a second groups of filmy internal electrodes, the electrodes of said first and second groups being alternately arranged and interposed one by one between two adjacent ceramic sheets, a first external electrode connected to an edge of each of the internal electrodes of said first group and a second external electrode connected to an edge of each of the internal electrodes of said second group, wherein spaces are provided between said first external electrode and each of the internal electrodes of said second group and between said second external electrode and each of the internal electrodes of said first group. According to the invention, there is also provided a method of manufacturing said laminated ceramic devices.
