A high capacitance, a short discharge response time and a high power performance are obtained. The macroreticular carbonaceous material has a total surface area of 500 m 2 / g or more to 2500 m 2 / g, and 20% to 80% of the total surface area is due to pores having a diameter of 17 angstroms to 100,000 angstroms. is there. In addition, the present invention provides at least one first distinguishable peak corresponding to a pore size of 20 angstroms or less, as measured using H-Kdv / dlog (W) pore size distribution, and BJHdv / dlog ( D) An energy storage device comprising a macroreticular carbonaceous material having at least one second distinguishable peak corresponding to a pore size greater than 20 angstroms as measured using the pore size distribution.
