Patent ID: 7903387

Claim:
A capacitor, comprising: a pair of conductor layers opposing each other at a prescribed distance; a plurality of substantially or nearly tube-shaped dielectric substances being substantially or nearly orthogonal to the conductor layers, and being connected at their respective opposite ends to internal main surfaces of the pair of conductor layers, and being formed of a high permittivity material; a first electrode being disposed between the plurality of the dielectric substances, surrounding each dielectric substrate, and being connected to one of the conductor layers at one end of the first electrode, and being insulated from another of the conductor layers at another end of the first electrode; and a plurality of substantially or nearly pillar-shaped second electrodes being disposed inside the plurality of the dielectric substances, respectively, and being connected to the another conductor layer at respective one ends of the second electrodes, and being insulated from the one conductor layer at respective another ends of the second electrode.
