PROBLEM TO BE SOLVED: To provide an electric double layer capacitor which ensures both large capacitance and low impedance. SOLUTION: This electric double layer capacitor consists of a pair of electrodes and an electrolysis solution touching the above pair of electrodes. Each of the electrodes has a carbon material, a specific surface area of the carbon material is smaller than or equal to 500 m<SP>2</SP>/g, and the volume of a fine pores with a diameter of 1 nm or smaller in the carbon material is smaller than or equal to 0.1 cm<SP>3</SP>/g. The electrolysis solution contains an electrolyte and an organic menstruum, and the organic menstruum contains the compounds of the chemical formula (1) and chained carbonate.
