Abstract: A multilayer ceramic capacitor may include a ceramic body including dielectric layers, first and second internal electrodes disposed in the ceramic body to face each other, the dielectric layer being interposed between the first and second internal electrodes, and first and second external electrodes covering both end surfaces of the ceramic body. The ceramic body may include an active layer as a capacitance forming part and a cover layer as a non-capacitive part disposed on at least one surface of upper and lower surfaces of the active layer, the cover layer including at least one buffer layer, and when a thickness of the cover layer is defined as tc, and a thickness of the buffer layer is defined as ti, ti/tc being in a range of 0.15 to 0.90 (0.15≦ti/tc≦0.90).
