US 10,593,481 B2 · Multilayer ceramic capacitor

Abstract

A multilayer ceramic capacitor and a method of manufacturing the same are disclosed. A base part of the multilayer ceramic capacitor includes ceramic dielectric and inner electrodes formed inside the ceramic dielectric, and a terminal of each of the inner electrodes is exposed out of one of the two opposite sides of the base part, to form inner electrode terminals. First outer electrodes are formed on the two sides of the base part and the outside of the inner electrode terminals, and second outer electrodes are formed on the first outer electrodes. The first outer electrodes and the base part are formed together by sintering manner, and the second outer electrodes are formed by metal powder and resin material, thereby solving the problem that the vitreous component diffuses around, or solving the problem that plating solution permeates into the base part or the ceramic dielectric during plating process.
