1. A multilayer ceramic capacitor, comprising:
a ceramic body comprising a dielectric layer, and 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 to fourth surfaces and opposing each other, and also including a plurality of internal electrodes disposed in the ceramic body, exposed on the first and second surfaces and each having one end exposed through the third surface or the fourth surface; and
a first side margin portion and a second side margin portion arranged on the first and second surfaces of the ceramic body, respectively,
wherein the ceramic body comprises an active portion in which the plurality of internal electrodes are arranged to overlap each other with the dielectric layer interposed therebetween to form capacitance, and cover portions disposed above an uppermost internal electrode and below a lowermost internal electrode of the active portion, and
the first and second side margin portions comprise tin, and a content of the tin included in the first and second side margin portions is different from a content of tin included in the cover portions.
