Abstract
A capacitor element includes a pair of conductor layers, a plurality of generally tube-shaped dielectric substances, a first electrode outside the dielectric substances and second electrodes in the insides thereof, and insulation caps for insulating the first electrode from the conductor layer, wherein an electrode material is filled in gaps of a structure of an oxide base material resulting from anodic oxidation of a metal, and then, the structure is removed and replaced by a high permittivity material.
