1. A capacitor comprising:
a first support portion;
a second support portion facing the first support portion with a distance therebetween;
a plurality of first conductive columnar portions supported by the first support portion and that extend along a first direction from the first support portion toward the second support portion, with each of the first conductive columnar portions having a nanosized outer diameter;
a first dielectric layer that coats each of the plurality of first conductive columnar portions;
a plurality of second conductive columnar portions supported by the second support portion and that extend along a second direction from the second support portion toward the first support portion, with each of the second conductive columnar portions having a nanosized outer diameter;
a second dielectric layer that coats each of the plurality of second conductive columnar portions; and
a conductive portion disposed on the first dielectric layer and facing at least a part of each of the plurality of first conductive columnar portions with the first dielectric layer interposed therebetween, and disposed on the second dielectric layer and facing at least a part of each of the plurality of second conductive columnar portions with the second dielectric layer interposed therebetween,
wherein a tip of each of the plurality of second conductive columnar portions is located closer to the first support portion than a tip of each of the plurality of first conductive columnar portions.
