An electric double layer capacitor using activated carbon as a polarizable electrode is provided with a large capacity electric double layer capacitor that does not require a large-scale manufacturing facility and can be manufactured at a low cost. It is an issue. In an electric double layer capacitor in which a polarizable electrode 3 using activated carbon, a collecting electrode 1, a separator 2, and an aqueous electrolyte 6 are accommodated in a container 7, the polarizable electrode 3 An activated carbon, the iron collector electrode 1, and a potassium hydroxide aqueous solution, a sodium hydroxide aqueous solution, or a mixture thereof serving as the electrolytic solution 6 were sealed in a container 7.
