1. A multilayer ceramic capacitor, comprising:
a body including a dielectric layer, and first and second internal electrodes layered in a third direction with the dielectric layer interposed therebetween and having first and second connection portions, respectively, the body including first and second surfaces opposing each other in the third direction, third and fourth surfaces opposing each other in a first direction, and fifth and sixth surfaces opposing each other in a second direction;
a first external electrode connected to the first internal electrode and disposed on the fifth surface of the body; and
a second external electrode connected to the second internal electrode, spaced apart from the first external electrode, and disposed on the fifth surface of the body,
wherein the first connection portion of the first internal electrode is connected to the first external electrode,
wherein the second connection portion of the second internal electrode is connected to the second external electrode,
wherein in a first direction-second direction cross-section, a substantially entire surface, being in contact with one of the first and second external electrodes, of one of the first and second connection portions has a rounded shape, and
wherein in the first direction-second direction cross-section, a radius of curvature of the surface, being in direct contact with the one of the first and second external electrodes, of the one of the first and second connection portions is within a range of 0.1 to 1 times a width, in the second direction, of the one of the first connection portion and the second connection portion.
