    Abstract: A multilayer ceramic capacitor includes a ceramic body having a dielectric layer, a plurality of internal electrodes disposed in the ceramic body, and a first side margin portion and a second side margin portion arranged on end portions of the internal electrodes exposed through respective opposing surfaces of the ceramic body. The ceramic body includes an active portion having the plurality of internal electrodes arranged to overlap each other with the dielectric layer interposed therebetween to form capacitance, and cover portions disposed above an uppermost and below a lowermost internal electrode of the active portion. The first and second side margin portions include tin (Sn), and a content of Sn included in the first and second side margin portions is greater than a content of Sn included in the dielectric layer of the active portion.
