Disclosed herein are a multilayer ceramic electronic component and a method for manufacturing the same. The multilayer ceramic electronic component includes a multilayer body in which dielectric layers and internal electrode layers are alternately stacked and external electrodes, wherein a portion in the internal electrode layers positioned in a marginal portion in which vertically neighboring internal electrode layers in the multilayer body is not overlapped with each other has a thickness thicker than that of a portion of the internal electrode layer positioned in an overlapped portion in which the vertically neighboring internal electrode layers are overlapped with each other, such that an accumulated stepped height difference in the marginal portion is reduced.
