摘要:
A capacitor includes a dielectric substrate and a large number of filamentous conductors formed to penetrate through the dielectric substrate in a thickness direction thereof. An electrode is connected to only respective one ends of a plurality of filamentous conductors constituting one of groups each composed of a plurality of filamentous conductors. The electrode is disposed in at least one position on each of both surfaces of the dielectric substrate, or in at least two positions on one of the surfaces. Further, an insulating layer is formed on each of both surfaces of the dielectric substrate so as to cover regions between the electrodes, and a conductor layer is formed on the corresponding insulating layer integrally with a desired number of electrodes.
