Zusammenfassung:An object of the present invention is to provide a carbonaceous material used for an electric double layer capacitor having a high electrostatic capacity and capable of maintaining the high electrostatic capacity and energy density over a long period and a method for producing the same. The present invention relates to a carbonaceous material having a specific surface area of 1,200 m 2 /g to 1,800 m 2 /g according to a BET method, an R-value of 1.2 or more and a G-band half-value width of 70 cm -1 or more according to a Raman spectrum.
