摘要： 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.

摘要： A conductive paste capable of forming a terminal electrode in which sintering proceeds while the viscosity of the glass is maintained during the sintering of the conductive component, so that the softened glass is prevented from flowing into the interface between the ceramic element assembly and the terminal electrode or from flowing on the surface of the terminal electrode, and furthermore, sufficient glass remains in the cavity of the terminal electrode film, so that an excellent seal is provided against the penetration of the plating solution, and the so-called “adhesion defect” is prevented from occurring, is provided. In addition, a ceramic electronic component is provided. The conductive paste is composed of a conductive component containing at least one of Cu and Ni, a glass frit and an organic vehicle, in which the glass frit contains a crystallizable glass, and the sintering starting temperature of the conductive component is higher than the crystallization starting temperature of the crystallizable glass and lower than the remelting temperature of the crystallizable glass.
