Claim 0:
1. A multilayer ceramic capacitor comprising:
a ceramic body including dielectric layers, and including a first surface and a second surface opposing each other, a third surface and a fourth surface connecting the first and second surfaces and opposing each other, and a fifth surface and a sixth surface connected to the first, second, third, and fourth surfaces and opposing each other;
a plurality of internal electrodes disposed in the ceramic body, extending to the first and second surfaces, and extending to only one of the third surface or the fourth surface; and
a first side margin portion and a second side margin portion respectively arranged on end portions of the internal electrodes extending to the first and second surfaces,
wherein the ceramic body comprises an active portion comprising the plurality of internal electrodes arranged to face each other with the dielectric layers interposed therebetween to form capacitance, and cover portions disposed above an uppermost internal electrode and below a lowermost internal electrode in the ceramic body,
the cover portions each include a first region adjacent to the fifth and sixth surfaces of the ceramic body, and a second region adjacent to the uppermost or lowermost internal electrode, wherein an average size of dielectric grains included in the second region of each of the cover portions is larger than an average size of dielectric grains included in the first region of each of the cover portions, and
wherein a content of magnesium (Mg) included in the second region of each of the cover portions is different from a content of magnesium (Mg) included in the first region of each of the cover portions.
