There is provided a multilayer ceramic capacitor including a ceramic body having first and second side surfaces and third and fourth end surfaces, a plurality of internal electrodes and having one ends exposed to the third or fourth end surface, and first and second side margin parts formed so that an average thickness from the first and second side surfaces to edges of the internal electrodes is 18 μm or less, wherein when the first or second side margin part is divided into two regions by a virtual line obtained by connecting mid points of distances between the edges of the internal electrodes and points at which lines extended from the internal electrodes contact the first or second side surface, when a region adjacent to the internal electrodes is defined as S1 and a porosity of S1 is defined as P1, P1 is in a range of 1 to 20 (1≦P1≦20).
