  • Patent number: 10354798
    Abstract: A multilayer ceramic capacitor includes: a ceramic body having first and second surfaces opposing each other and third and fourth surfaces connecting the first and second surfaces to each other; a plurality of internal electrodes disposed in the ceramic body, exposed to the first and second surfaces, and each having one end exposed to the third or fourth surface; and first and second side margin portions disposed on the first and second surfaces and covering exposed surfaces of the internal electrodes. A dielectric composition contained in the first and second side margin portions is different from a dielectric composition contained in the ceramic body, the first and second side margin portions contain a barium titanate-based base material powder and magnesium (Mg), manganese (Mn), and aluminum (Al) as accessory ingredients, and a content ratio of manganese (Mn) to magnesium (Mg), manganese (Mn), and aluminum (Al) satisfies 0.316?Mn/(Mn+Mg+Al)?0.
