Stacked-type piezoelectric device and production method
摘要:
A stacked-type piezoelectric device comprising a ceramic stacked body constituted by alternately stacking ceramic layers and internal electrode layers one upon another, and a pair of external electrodes bonded respectively to a pair of bond surfaces formed on an outer peripheral surface of the ceramic stacked body, in which the ceramic stacked body has, at least partially in a peripheral direction, a groove portion recessed in a groove shape from its outer peripheral surface in such a fashion as to be adjacent to a stacking surface of each internal electrode layer, and a production method thereof.
