<p>PROBLEM TO BE SOLVED: To provide an electrochemical capacitor capable of suppressing a decrease (dry-up) in an impregnating amount of an electrolyte in a separator and contributing to a reduction in an internal resistance. SOLUTION: In the electrochemical capacitor, a polarizable electrode containing a carbon material having a fine crystal carbon similar to a partly oxidized graphite is dipped in an organic electrolyte. The electrode is volumetrically expanded by charging and volumetrically contracted by discharging. The electrode 26 has recesses 38, slits 34, holes 35 or an opening part 40 having in combination of them.</p> |
