1. A multilayer ceramic capacitor, comprising:
a ceramic body having first and second main surfaces perpendicular to a first axis and first and second end surfaces perpendicular to a second axis orthogonal to the first axis, the ceramic body including:
a plurality of ceramic layers laminated in a direction of the first axis, and
a plurality of first and second internal electrodes alternately laminated with the plurality of ceramic layers respectively interposed therebetween in the direction of the first axis, the first and second internal electrodes being drawn out to the first and second end surfaces, respectively; and
first and second external electrodes covering the first and second end surfaces of the ceramic body, respectively,
wherein the plurality of first and second internal electrodes include a plurality of first and second standard internal electrodes and a plurality of first and second special internal electrodes,
wherein in the plurality of first and second special internal electrodes, an area density of a metal material is lower than that in the plurality of first and second standard internal electrodes, and
wherein the plurality of first and second special internal electrodes are successively laminated in a section of the ceramic body that is closer to one side of one of the first and second main surfaces than a center in the direction of the first axis.
