Patent ID: 8638542

Claim:
A capacitor, comprising: a dielectric substrate; a large number of filamentous conductors formed in the dielectric substrate so as to penetrate through the dielectric substrate in a thickness direction thereof, the large number of filamentous conductors constituting groups each composed of a plurality of filamentous conductors; and a plurality of electrodes each connected to only one ends of the plurality of filamentous conductors of each group, wherein, the plurality of filamentous conductors, having the plurality of electrodes connected to only one ends thereof, has an insulating layer connected to another end thereof, wherein among the groups respectively connected to the electrodes, any two groups next to each other are of capacitance, wherein among the plurality of electrodes two electrodes respectively connected to the any two groups next to each other are disposed on respective surfaces of both surfaces of the dielectric substrate so as to not face each other, or at two positions on one surface of the both surfaces, and wherein the large number of filamentous conductors includes isolated filamentous conductors not electrically connected to the electrodes, the isolated filamentous conductors being disposed between the groups next to each other.
