PROBLEM TO BE SOLVED: To provide an electrochemical capacitor of a low cost and a high capacity by carrying a ruthenium (IV) oxide on activated carbon. SOLUTION: In this electrochemical capacitor having a pair of electrodes 11 and 12, an ion permeable porous separator 15 disposed between the electrodes 11 and 12 for electronically insulating them and an electrolyte solution immersed in these, the pair of electrodes 11 and 12 are electrodes containing complex activated carbon fine particles manufactured by a process of neutralizing with an alkali after a halide of a transition metal element of Group VIII is immersed in activated carbon fine particles 13 and 14 from a water solution containing the halide of the transition metal element 6 Group VIII. |
