1. A multilayer ceramic capacitor, comprising:
a ceramic body having a pair of end surfaces perpendicular to a first axis and a pair of side surfaces perpendicular to a second axis that is orthogonal to the first axis, the ceramic body including:
a first internal electrode having a first electrode main body portion and a pair of first lead-out portions led out from the first electrode main body portion to the pair of end surfaces, respectively; and
a second internal electrode having a second electrode main body portion and a pair of second lead-out portions led out from the second electrode main body portion to the pair of side surfaces, respectively, the second internal electrode facing the first internal electrode in a direction of a third axis that is orthogonal to the first and second axes;
a pair of first external electrodes arranged on the pair of end surfaces, respectively, and connected to the pair of first lead-out portions of the first internal electrode; and
a pair of second external electrodes arranged on the pair of side surfaces, respectively, and connected to the pair of second lead-out portions of the second internal electrode,
wherein each of the first electrode main body portion of the first internal electrode and the second electrode main body portion of the second internal electrode has a first current regulating portion that is a cutout portion spaced apart from an outer edge of the corresponding first or second electrode main body portion and having a shape in which a ratio of a maximum longitudinal dimension to a maximum transverse dimension is greater than 1,
wherein the first internal electrode is physically continuous between the first external electrodes, and the second internal electrode is physically continuous between the second external electrodes.
