简介 A multilayer ceramic capacitor includes a ceramic body including first and second surfaces opposing each other, and third and fourth surfaces connecting the first and second surfaces, a plurality of internal electrodes disposed inside the ceramic body, exposed from the first and second surfaces, and having an end exposed from the third surface or the fourth surface, and a first side margin and a second side margin respectively disposed on the first and second surfaces, from which end portions of the plurality of internal electrodes are exposed. The first and second side margins include a base material powder of a barium titanate-based base powder and a subcomponent. The subcomponent includes terbium (Tb) as a first subcomponent including a lanthanide rare earth element, and a content ratio of the terbium (Tb) to a content of the first subcomponent (RE) excluding the terbium (Tb) satisfies 0.110≤Tb/RE≤2.333.
