There is provided a multilayer ceramic electronic component. The multilayer ceramic electronic component includes a ceramic main body including a dielectric layer, and first and second internal electrodes disposed to face each other within the ceramic main body and having the dielectric layer interposed therebetween. When an average roughness of center lines of the first and second internal electrodes is Ra, a maximum distance from a virtual line corresponding to Ra to a bottom of a pit (d) formed below the virtual line is 0.1 &#x3bc;m to 13 &#x3bc;m. The surface roughness of the internal electrode printed surface is improved to decrease the occurrence of electrical shorts.

Multilayer ceramic electronic component and manufacturing method thereof

There is provided a multilayer ceramic electronic component, including: a ceramic body having dielectric layers and first and second internal electrodes alternately stacked therein; and first and second external electrodes electrically connected to the first and second internal electrodes and formed at both ends of the ceramic body, wherein the ceramic body includes an effective layer contributing to capacitance formation and a protective layer provided on at least one of upper and lower surfaces of the effective layer, the protective layer including one or more step absorbing layers provided at both ends thereof, so that the multilayer ceramic electronic component can have excellent reliability by reducing defects such as electrode spreading, cracks, delamination and the like.
