An alkali-activated carbon for an electric double layer capacitor electrode is provided in which the alkali-activated carbon has a first pore group having a pore diameter D in the range of D<=2 nm, a second pore group having a pore diameter D in the range of 2 nm<D<=10 nm, and a third pore group having a pore diameter D in the range of 10 nm<D<=300 nm. When the pore volume of the first pore group is Pv 1 , the pore volume of the second pore group is Pv 2 , the pore volume of the third pore group is Pv 3 , and the sum total Pv 0 of the pore volumes is Pv 0 =Pv 1 +Pv 2 +Pv 3 , the pore volumes being obtained by a nitrogen gas adsorption method, the proportion A of the pore volume Pv 1 of the first pore group relative to the sum total Pv 0 of the pore volumes is A>=60%, and the proportion B of the pore volume Pv 2 of the second pore group relative to the sum total Pv 0 of the pore volumes is B>=8%. |
