SOLUTION: The specific surface area of a carbon material obtained by Bet method of nitrogen adsorption is 800 m /g or more and 2000 m /g or less and a mean layer face interval thereof obtained by X ray diffraction method is 0.36 nm or less. The carbon material is used as powder and its average grain diameter is 5 μm or more and 100 μm or less. The carbon material is manufactured by adding 2 or 3 cyclic aromatic compound whose boiling point is 200 deg.C or higher or a mixture thereof as additive to pitch such as petroleum pitch and coal pitch and heating and mixing it, and thereafter, it is molded and a pitch molded item is obtained. Then, additive is extracted from a pitch molded item by solvent with low solubility to pitch and high solubility to additive, the obtained porous pitch is oxidized by using oxidizer, the obtained porous pitch which is insoluble to heat is subjected to activation treatment and activated carbon-like carbon material is obtained.
