Abstract
A multilayer ceramic capacitor and a method of manufacturing the same is provided. The capacitor comprises dielectric layers and internal electrode layers alternately stacked. Two of the internal electrode layers that are located outermost and/or at least one of the internal electrode layers that is located inside each outermost internal electrode layer are substantially oxidized and do not function as electrodes. The capacitance of the multilayer ceramic capacitor depends on the unoxidized internal electrode layers other tan the oxidized ones. The method of manufacturing a multilayer ceramic capacitor comprises forming green dielectric layers, forming green internal electrode layers, preparing a green ceramic chip, forming green external electrodes, and firing the green ceramic chip.
