Abstract
There is provided a carbon material for polarizable electrodes in which a heterocyclic aromatic compound is adsorbed on an activated carbon, wherein the heterocyclic aromatic compound comprises a five- or six-membered ring having two or more nitrogen atoms as ring-forming atoms; a ratio (N/C) of nitrogen atoms to carbon atoms in the heterocyclic aromatic compound is 0.4 or more; 1 to 35 parts by mass of the heterocyclic aromatic compound is adsorbed based on 100 parts by mass of the activated carbon; and the carbon material for polarizable electrodes has a benzene adsorption capacity of 25 to 75% by mass.
