<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing activated carbon in which the corrosion of the inside of a reaction furnace caused by the scattering of an alkali metal compound and/or an alkali metal, and the danger of the ignition or the explosion of the alkali metal in alkali activation are eliminated, and to provide an electrical double layer capacitor using the activated carbon manufactured by the manufacturing method as an electrode. <P>SOLUTION: In the method of manufacturing activated carbon, a capturing layer, in which an adsorbing agent capable of capturing the alkali metal compound and/or the alkali metal scattered in the activation reaction is filled, is formed in the upper part of an alkali activation reaction vessel, and/or carbon dioxide is allowed to be contained in a specified amount in an atmospheric gas in the reaction furnace in which the alkali activation reaction vessel is mounted, when the alkali activation is carried out by adding the alkali metal compound into a carbon precursor. The electrical double layer capacitor using activated carbon as the electrode is manufactured by the method. <P>COPYRIGHT: (C)2004,JPO |
