Claim 5:
6. A composite capacitor comprising:
a plurality of capacitors stacked on each other; and
an insulating section that covers peripheral surfaces of the plurality of capacitors about a central axis of the plurality of capacitors, a stacking direction of the plurality of capacitors being a direction of the central axis,
each of the plurality of capacitors including:
a support electrode layer;
a plurality of columnar conductors that extend from a side of the support electrode layer along the stacking direction and that each have a nano-size outer diameter;
a dielectric layer that covers the support electrode layer and the plurality of columnar conductors; and
a counter electrode layer that covers the dielectric layer and that opposes the support electrode layer and the plurality of columnar conductors with the dielectric layer interposed therebetween,

wherein the plurality of capacitors include a first capacitor and a second capacitor connected in parallel with the first capacitor,
wherein the counter electrode layer of the first capacitor is electrically connected to the support electrode layer of the second capacitor, the second capacitor being positioned most closely to the first capacitor at the side of the counter electrode layer of the first capacitor in the stacking direction, and
wherein the plurality of capacitors further include a third capacitor between the first capacitor and the second capacitor, the third capacitor being connected in series with the first capacitor.
