Abstract
A multilayer ceramic capacitor includes a ceramic body including a dielectric layer and having first and second surfaces opposing each other in a width direction, third and fourth surfaces connecting the first and second surfaces in a length direction, and fifth and sixth surfaces opposing each other in a thickness direction, internal electrodes disposed inside the ceramic body, exposed through the first and second surfaces, and having one end portion exposed through the third or fourth surface, and first and second side margin portions disposed on edges of the internal electrodes, exposed through the first and second surfaces. In a cross-section cut along a width-thickness plane of the ceramic body, an area of an oxide region disposed on the edges of the internal electrodes is less than 10% of an overall area of the internal electrodes exposed through the first and second surfaces.
