Abstract: A multilayer ceramic capacitor includes a ceramic body including an active portion including dielectric layers and internal electrodes that are alternately stacked and a margin portion disposed on outer surfaces of the active portion; and external electrodes disposed on outer surfaces of the ceramic body. The margin portion includes an inner half adjacent to the active portion and an outer half adjacent to the edge of the ceramic body, and a porosity of the inner half is greater than a porosity of the outer half.
