1. A multilayer ceramic capacitor comprising:
a capacitor body including a plurality of dielectric layers, a plurality of first inner electrodes, and a plurality of second inner electrodes that are stacked in a stacking direction, and first and second outer surfaces that face each other in the stacking direction;
at least one first via-conductor inside the capacitor body and electrically connected to the first inner electrodes;
at least one second via-conductor inside the capacitor body and electrically connected to the second inner electrodes;
a first extended electrode portion electrically connected to the at least one first via-conductor and provided on one of the first and second outer surfaces of the capacitor body such that the first extended electrode portion extends to a location different from a location at which the first extended electrode portion is connected to the at least one first via-conductor;
a second extended electrode portion electrically connected to the at least one second via-conductor and provided on the one of the first and second outer surfaces of the capacitor body such that the second extended electrode portion extends to a location different from a location at which the second extended electrode portion is connected to the at least one second via-conductor;
a plurality of first outer electrodes electrically connected to the first extended electrode portion at the one of the first and second outer surfaces of the capacitor body;
a plurality of second outer electrodes electrically connected to the second extended electrode portion at the one of the first and second outer surfaces of the capacitor body; and
an insulative resin providing insulation between the first extended electrode portion and the second extended electrode portion, and between the plurality of first outer electrodes and the plurality of second outer electrodes; wherein
a number of the plurality of first outer electrodes electrically connected to the first extended electrode portion at the one of the first and second outer surfaces of the capacitor body is greater than a number of the at least one first via-conductor; and
a number of the plurality of second outer electrodes electrically connected to the second extended electrode portion at the one of the first and second outer surfaces of the capacitor body is greater than a number of the at least one second via-conductor.
