<p>PROBLEM TO BE SOLVED: To provide a large-capacitance electrochemical capacitor which has a specific capacitance higher than that of a prior art electric double layer capacitor and which is lower in manufacturing cost than a pseudo-capacitance capacitor using fine particles of ruthenium oxide. SOLUTION: In the electrochemical capacitor having a pair of electrodes, a porous separator interposed between the pair of electrodes, and an electrolyte impregnated in the separator, the material of at least one of the electrodes is made of titanium oxide, hydrate oxide or fine particles of these hydride containing an element capable of conducting oxidation and reduction, which is carried on porous active carbons or active carbon fibers.</p> |
