    摘要： A multilayer ceramic capacitor includes a ceramic body including a dielectric layer, a plurality of first and second internal electrodes disposed inside the ceramic body, exposed to the first and second surfaces, and having ends exposed to the third or fourth surface, and a first side margin portion and a second side margin portion disposed on side portions of the plurality of first and second internal electrodes exposed to the first and second surfaces. A ratio Db/Da satisfies 1.00 to 1.07, inclusive, where ‘Db’ is a distance, in a stacking direction of the dielectric layer, between both end points of respective edge regions of the first side margin portion and the second side margin portion, and ‘Da’ is a distance in a central region of the ceramic body in the stacking direction.
