摘要:
There is provided a multi-layered ceramic capacitor with reduced internal resistance by forming internal electrode groups including internal electrodes having different lengths. The multi-layered ceramic capacitor of the present invention includes a sintered ceramic body part in which cover layers are provided on both surfaces thereof as an outermost layer and a plurality of ceramic layers are stacked therebetween, first and second external electrodes each formed on an outer surface of the sintered ceramic body part, a plurality of first and second internal electrode groups adjacent to each other in a stacking direction of the plurality of ceramic layers, having the ceramic layer therebetween, and including 2N or 2N+1 (N is an integer number larger than 1) internal electrodes electrically connected to the first and second external electrodes, wherein the 2N or 2N+1 (N is an integer number larger than 1) internal electrodes are disposed to face at least one internal electrode of other adjacent internal electrode groups. A length of each internal electrode has a pyramid shape.
