A multilayer ceramic electronic component includes a ceramic main body having internal and floating electrode layers laminated therein and spaced apart from each other; and external electrodes formed on ends of the ceramic main body and including a first layer including a conductive metal and a second layer formed on the first layer and including a conductive resin. When Tc is thickness of a cover layer, G is gap between internal electrodes, L1 is length from either end of the ceramic main body in a length direction thereof to an end of the first layer formed on the upper or lower surface of the ceramic main body, Te is thickness of the internal electrode, Td is distance between internal and floating electrode layers, Lm is length of a margin part of the floating electrode layer, and L is length of the ceramic main body, Tc≦80 μm, (1.5)Lm≦G≦(L−2Lm), and L1
