Patent ID: 6839221

Claim:
A multilayer ceramic capacitor comprising: an effective dielectric material section made by stacking dielectric ceramic layers, that include a main crystal phase comprising at least BaTiO 3 as main component and a secondary phase comprising mainly SiO 2 which forms grain boundary and triple point boundary, and internal electrode layers alternately one on another; external cover dielectric layers that are formed on the upper and lower surfaces in the stacking direction of said effective dielectric material section and include a main crystal phase and a secondary phase comprising at least the same components as those of said dielectric ceramic layer; and external electrodes that are electrically connected with the internal electrode layers led out onto both end faces of said effective dielectric material section which includes said external cover dielectric layers, wherein said external cover dielectric layers comprises ceramics having lower sinterability than the dielectric ceramic layer of said effective dielectric material section.
