Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of manufacturing the electrode of an electric double layer capacitor having a high capacity in a short time.SOLUTION: In an electrolytic solution of phosphoric acid or sulphuric acid, a rectangular wave having a lower limit potential from 0.0 V to +0.3 V for a reversible hydrogen electrode used as a reference electrode and an upper limit potential in the range from +0.5 V to +0.7 V is applied to a carbon substrate, i.e. the electrode body of an electric double layer capacitor, for 10-60 sec of the upper limit potential holding time until a charge amount of 3,800-120,000C flows per 1 mol of carbon contained in the carbon substrate.
