1. A multilayer ceramic electronic component comprising:
a ceramic body including:
an electrode-stacked portion that includes a plurality of ceramic layers stacked in a direction of a first axis and a plurality of internal electrodes disposed between the plurality of ceramic layers and alternately led out to respective sides along a second axis orthogonal to the first axis,
first and second cover portions opposed to each other in the direction of the first axis with the electrode-stacked portion interposed therebetween, and
first and second side margin portions opposed to each other in a direction of a third axis orthogonal to the first axis and the second axis with the electrode-stacked portion interposed therebetween; and
first and second external electrodes connected to the plurality of internal electrodes and opposed to each other in a direction of the second axis across the ceramic body,
wherein a dimension in the direction of the first axis of the ceramic body is larger than a dimension in the direction of the third axis of the ceramic body, and
wherein the plurality of internal electrodes contain ceramic particles, and
wherein the plurality of internal electrodes include:
a plurality of first peripheral internal electrodes collectively disposed in a peripheral portion at a side of the first cover portion in the direction of the first axis,
a plurality of second peripheral internal electrodes collectively disposed in another peripheral portion at a side of the second cover portion in the direction of the first axis, and
a plurality of central internal electrodes collectively disposed closer to a center in the direction of the first axis than the plurality of first peripheral internal electrodes and the plurality of second peripheral internal electrodes, and
wherein an average particle size of ceramic particles contained in each of the plurality of first peripheral internal electrodes and the plurality of second peripheral internal electrodes is larger than an average particle size of ceramic particles contained in each of the plurality of central internal electrodes.
