PRODUCTION OF ELECTROSTRICTIVE EFFECT ELEMENT

Japanese Patent JPS6127687

A

PURPOSE:To improve the reliability of insulation and to obtain high field effect driving and generation of large strain simultaneously, by depositing an organic material on every second layer of internal electrodes on the side faces of a layered body, heating the material to secure it thereon and baking glass powder on the layered body. CONSTITUTION:A layered body of electrostrictive material is cut off along two lines such that every second layer of internal electrodes is exposed on the surface. Temporary external electrodes 25 and 26 are applied and baked on the surfaces of the body exposed by cutting. Two side faces different from the surfaces provided with the temporary external electrodes are further cut off so that whole layers of internal electrodes 23 and 24 are exposed. A beltlike film 27 of an organic material is formed by electrode position on the exposed portions of the internal electrodes on the layered body, and glass powders 28 and 29 are then deposited thereon. Only the glass powder 28 deposited on the organic material film 27 are scraped by a scraper or the like and baked to form glass coat films 31. Similar glass coat films are formed in a similar manner and procedures on the opposite end face at the positions each shifted by one internal electrode layer. External electrodes 32 are provided on the front and back end faces of the body, which is then cut off along the broken lines in the drawing to obtain the final electrostrictive effect elements.
