Multilayer ceramic electronic component

A multilayer ceramic electronic component comprising:

• a ceramic body having a hexahedral shape including at least one rounded corner and including dielectric layers and first and second internal electrodes stacked to be alternately exposed through first and second external sides with the dielectric layer interposed therebetween;
• and
• first and second external electrodes disposed on the first and second external sides of the ceramic body and electrically connected to the first and second internal electrodes, respectively,
• wherein the first and second external electrodes respectively include first and second base electrode layers which at least partially contact the first and second external sides of the ceramic body, and first and second plating layers disposed to cover the first and second base electrode layers, respectively, and
• wherein CP/CT is within a range from 1.6 to 2.4, where CP is a length of a rounded boundary line of the at least one rounded corner of the ceramic body viewed in a cross-section in length and thickness directions, and CT is a thickness of one of the first and second base electrode layers at a central point in the thickness direction.
