ABSTRACT:
A multilayer ceramic device includes an external electrode disposed on a piezoelectric ceramic body including internal electrodes. The external electrode is a sintered body in which an Ag grid is integrally embedded in a coating film primarily composed of Ag. Therefore, it is possible to obtain a multilayer ceramic device having outstanding properties, such as durability and moisture resistance, without leading to poor electrical continuity and a decrease in conductivity even when a continuous operation is performed for a prolonged period of time.
