Multilayer piezoelectric element and method of producing the same |
摘要 |
An electronic part comprises a main part, a terminal electrode, and a film. The main part includes a sintered piezoelectric ceramic element (101), wherein a plurality of internal electrode layers (110,111,112) and piezoelectric layers (113) are alternately stacked. The terminal electrode (114) is provided at an edge of the sintered piezoelectric ceramic element and electrically conducting to the internal electrodes. Insulating films (115) are provided on surfaces of the sintered piezoelectric ceramic element and the exposed internal electrodes, and are made of a glass insulating material. <IMAGE> |
