1. A multilayer ceramic capacitor, comprising:
a ceramic body comprising a first surface and a second surface facing each other in a first direction, a third surface and a fourth surface facing each other in a second direction and connecting the first surface and the second surface, a fifth surface and a sixth surface facing each other in a third direction and connecting the first surface and the second surface;
a plurality of first internal electrodes and a plurality of second internal electrodes disposed inside the ceramic body;
a first external electrode disposed on the ceramic body and connected to the plurality of first internal electrodes, the first external electrode comprising a first conductive carbon layer connected to the plurality of first internal electrodes on the first surface of the ceramic body and extending to at least one surface among the third surface, the fourth surface, the fifth surface, and the sixth surface, and a first plated layer covering the first conductive carbon layer; and
a second external electrode disposed on the ceramic body and connected to the plurality of second internal electrodes, the second external electrode comprising a second conductive carbon layer connected to the plurality of second internal electrodes on the second surface of the ceramic body and extending to at least one surface among the third surface, the fourth surface, the fifth surface, and the sixth surface, and a second plated layer covering the second conductive carbon layer,
wherein end portions of the plurality of first internal electrodes are exposed through the first surface of the ceramic body, and end portions of the plurality of second internal electrodes are exposed through the second surface of the ceramic body, and
wherein the first conductive carbon layer is in direct contact with the first surface of the ceramic body between the exposed end portions of the plurality of first internal electrodes, and the second conductive carbon layer is in direct contact with the second surface of the ceramic body between the exposed end portions of the plurality of second internal electrodes.
