PROBLEM TO BE SOLVED: To provide an electric double-layer capacitor which has a large electrostatic capacity, a low resistance and high reliability. SOLUTION: An electric double-layer capacitor has electrodes made of carbon material which contains 0.1 to 50 wt.% of metal-equivalent of particles of metal or metal compound, has a specific surface area of 500 to 2500 m2/g, and whose ratio of a specific surface area produced by micropores calculated by a t-plotting method in accordance with a nitrogen adsorption isotherm to the whole specific surface area is not larger than 70% and organic electrolyte. |
