1. A multilayer ceramic capacitor comprising:
a plurality of dielectric layers and a plurality of inner electrode layers that are stacked and each made of a ceramic material; wherein
each of the plurality of inner electrode layers includes a plurality of through holes;
inside the plurality of through holes, a portion of the dielectric layers is packed and Si that is derived from the plurality of dielectric layers segregates; and
an average circularity of the plurality of through holes is equal to or greater than about 0.6.
