Multilayer ceramic electronic component and method of manufacturing the same

A multilayer ceramic electronic component comprising:

• a ceramic body including a plurality of active parts including a plurality of dielectric layers and a plurality of internal electrodes that are alternately disposed;
• an interlayer margin part separating the active parts from each other within the ceramic body;
• cover parts disposed on an upper portion of an uppermost internal electrode and a lower portion of a lowermost internal electrode among the plurality of internal electrodes, within the ceramic body,
• wherein the interlayer margin part and the cover parts are formed of a dielectric composition different from that of the dielectric layers and contain magnesium in an amount of lmol % or more.

A method of manufacturing a multilayer ceramic electronic component, the method comprising:

• preparing a plurality of first green sheets for forming an active part, a plurality of second green sheets for forming an interlayer margin part, and a plurality of third green sheets for forming a cover part;
• printing an internal electrode pattern on the plurality of first green sheets;
• stacking the first to third green sheets to form a green sheet multilayer body;
• and
• sintering the green sheet multilayer body to prepare a ceramic body including a plurality of active parts, an interlayer margin part separating the active parts from each other, and cover parts disposed on an upper portion of an uppermost active part and a lower portion of a lowermost active part among the plurality of active parts,
• wherein the second green sheets and the third green sheets contain magnesium in an amount of 1 mol % or more.
