1. A capacitor array comprising:
a capacitor layer including a plurality of capacitor portions divided by a plurality of through-portions and arranged in a plane,
wherein the capacitor portions each include a first electrode, a second electrode, and a dielectric layer between the first electrode and the second electrode, and each of the capacitor portions having a first main surface and a second main surface that are opposite to each other in a thickness direction thereof,
wherein the plurality of through-portions include a first through-portion extending in a first direction perpendicular to the thickness direction, and a second through-portion extending in a second direction perpendicular to the thickness direction and intersecting the first direction,
wherein, in a sectional view taken in the thickness direction, the first through-portion has a first taper that has a first width decreasing from one of the first main surface of the capacitor portion and the second main surface of the capacitor portion to another one of the first main surface and the second main surface, and the second through-portion has a second taper that has a second width decreasing from one of the first main surface of the capacitor portion and the second main surface of the capacitor portion to another one of the first main surface and the second main surface,
wherein the first taper has a first taper angle that is different from a second taper angle of the second taper,
wherein the capacitor layer further includes a first insulating portion over at least one of the first main surface of the capacitor portion and the second main surface of the capacitor portion, and
wherein the first insulating portion extends through the first through-portion and does not extend through the second through-portion.
