PIEZOELEKTRISCHES FESTKOERPERBAUELEMENT

摘要

A monolithic piezoelectric element comprising a sintered body comprising a plurality of ceramic layers which is provided with a first electrode group which includes a plurality of electrodes electrically connected with each other and located between alternate pairs of adjacent layers, and a second electrode group which includes a plurality of electrodes interposed between the electrodes of the first electrode group and electrically connected with each other. The two groups of electrodes are electrically isolated from each other. The respective electrodes of the first and second electrode groups are electrically connected with each other through through-holes formed in the sintered body.
