Abstract: A method of manufacturing a multilayer ceramic capacitor includes stacking dielectric sheets on which internal electrode patterns are printed, to form a multilayer body, forming additional dielectric sheets on portions of opposite side surfaces of the multilayer body, and sintering the multilayer body to form a ceramic body in which internal electrodes are disposed. Here, the additional dielectric sheets form attachment parts on the opposite side surfaces of the ceramic body by the sintering of the multilayer body.
