A multilayer ceramic electronic component including: a ceramic body having a plurality of dielectric layers stacked therein; active layers including a plurality of first and second internal electrodes formed to be alternately exposed to both end surfaces of the ceramic body with the dielectric layers interposed therebetween; and first and second external electrodes formed on the both end surfaces of the ceramic body and electrically connected to the first and second internal electrodes, respectively. The active layers may include a first active layer including a ferroelectric layer and a second active layer including a paraelectric layer, the first and second active layers being alternately stacked.
