1. Activated carbon used for an electrochemical element comprising the activated carbon and an electrolytic solution,wherein under definitions that van der Waals molecular diameters of a cation, an anion, and a solvent contained in the electrolytic solution are denoted by Lc, La, and Ls, respectively;

  • minimum widths of van der Waals molecules of the cation, the anion, and the solvent are denoted by Lmin,c, Lmin,a, and Lmin,s, respectively;

    a maximum value of Lc, La, Ls, Lmin,c, Lmin,a, and Lmin,s is denoted by W1; and

    a minimum values of (Lc+La), (Lc+Ls), (La+Ls), (Lmin,c+Lmin,a), (Lmin,c+Lmin,s), and (Lmin,a+Lmin,s) is denoted by W2,a total pore volume of the activated carbon in which a slit width obtained by an MP method is W1 or more and W2 or less is 15% or more of a total pore volume in which the slit width is 2.0 nm or less.
