The present invention provides a carbon porous body having a mesoporous structure and a large difference in nitrogen adsorption amount with respect to a nitrogen relative pressure difference in a region where the nitrogen relative pressure is large. In the carbon porous body of the present invention, α of nitrogen adsorption isotherm measured at a temperature of 77K s The micropore volume calculated by curve analysis is 0.1cm 3 (ii) less than g, relative pressure P/P of nitrogen in the nitrogen adsorption isotherm 0 The mesopore volume calculated by subtracting the micropore volume from the nitrogen adsorption volume at 0.97 is small, and the nitrogen relative pressure P/P in the nitrogen adsorption isotherm 0 The nitrogen adsorption amount at 0.5 was 500cm 3 (STP)/g or less and nitrogen relative pressure P/P 0 The nitrogen adsorption amount at 0.85 was 600cm 3 (STP)/g or more and 1100cm 3 (STP)/g or less. |
