Abstract:
1. A capacitor comprising: a dielectric material that is formed of anodic metal oxide and has a determinable thickness; a pair of substantially or nearly comb-shaped surface electrodes that is formed on the same principal surface of the dielectric material, each surface electrode comprising a base portion and plural tooth portions connected to the base portion; and plural substantially or nearly columnar internal electrodes whose one ends are connected to each tooth portion of the pair of surface electrodes, said internal electrodes extending in the thickness direction of the dielectric material and being enclosed by a part of the dielectric material including their other ends opposite to the one ends in their entirety except the one ends, wherein the pair of surface electrodes are disposed on the surface of the dielectric material so that the respective tooth portions thereof are arranged alternately and in parallel through the dielectric material.
