Claim:
1. A high voltage electrode for an electric double layer capacitor, comprising: a through type aluminum sheet configured to have a plurality of through holes formed in the through type aluminum sheet so that the through holes are spaced apart from one another; a plurality of first hollow protrusion members extended from the through type aluminum sheet in such a way as to communicate with the through holes and protruded to a first side of the through type aluminum sheet; a plurality of second hollow protrusion members spaced apart from the plurality of first hollow protrusion members, extended from the through type aluminum sheet in such a way as to communicate with the through holes, and protruded to a second side of the through type aluminum sheet; a metal oxidation layer coated on the through type aluminum sheet, the plurality of first hollow protrusion members, and the plurality of second hollow protrusion members; a first active material sheet placed on a first surface of the through type aluminum sheet and bonded to the metal oxidation layer so that the plurality of first hollow protrusion members is buried; and a second active material sheet configured to have the plurality of second hollow protrusion members buried in the second active material sheet and placed on a second surface of the through type aluminum sheet and bonded to the metal oxidation layer so that the second active material sheet is connected to the first active material sheet through the plurality of first hollow protrusion members and the plurality of second hollow protrusion members, wherein: each of the plurality of first hollow protrusion members and the plurality of second hollow protrusion members is formed by perforating the through type aluminum sheet by applying pressure on the first side or second side of the through type aluminum sheet using one of a cylindrical pillar member, an elliptical pillar member, and a square pillar member each having a pointed tip so that the plurality of through holes is formed in the through type aluminum sheet, the plurality of first hollow protrusion members and the plurality of second hollow protrusion members are extended and protruded from the through type aluminum sheet in such a way as to respectively communicate with the plurality of through holes, and each of the through holes has one of a cylindrical shape, an oval, and a square shape by one of the cylindrical pillar member, the elliptical pillar member, and the square pillar member.
