Claim Text:
1. A carbon material consisting of activated carbon and having a pore distribution, which is obtained by a BJH method and is plotted on a graph with a pore diameter D on the abscissa and a derivative ΔV/ΔD of a pore volume V per unit mass or unit volume with respect to the pore diameter D on the ordinate, such that a ratio M1/M2 of the maximum value M1 of the derivative ΔV/ΔD in an interval of the pore diameter D from 10 to 100 nm with respect to the maximum value M2 of the derivative ΔV/ΔD in an interval of the pore diameter D from 2 to 10 nm is within a range of 1.5 to 10, the carbon material having an interplanar spacing for the (002) plane of 0.365 to 0.380 nm and a specific surface area of 300 to 900 m 2 /g, which is obtained by utilizing a BET adsorption isotherm.
