Multilayer ceramic capacitor and method of manufacturing the same

A multilayer ceramic capacitor comprising:

• a ceramic body including a dielectric layer, and including a first surface and a second surface opposing each other, a third surface and a fourth surface connected to the first surface and the second surface and opposing each other, and a fifth surface and a sixth surface connected to the first surface to the fourth surface and opposing each other;
• a plurality of internal electrodes disposed in the ceramic body, exposed from the first and second surfaces, and having one ends exposed from 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 exposed from the first and second surfaces,
• wherein the ceramic body comprises an active portion comprising the plurality of internal electrodes arranged to oppose each other with the dielectric layer interposed therebetween to form capacitance, and cover portions respectively disposed on upper and lower surfaces of the active portion,
• the first and second side margin portions respectively include a first region adjacent to an outer side surface of each of the side margin portions, and a second region adjacent to the internal electrodes exposed from the first and second surfaces, wherein the number of pores per unit area in the second region is less than the number of pores per unit area in the first region,
• wherein The first region and the second region include magnesium (Mg), a thickness of each of the internal electrodes is 0.4 μm or less.
