Abstract
The invention relates to a coin-type electric double-layered capacitor, including activated carbon electrode layers, an electrolytic solution, and a separator between a metal-made top vessel and a metal-made bottom vessel, and obtained by caulking and sealing the top vessel and the bottom vessel with a gasket and a sealing agent, wherein the edges of the top and bottom vessels overlap each other by 0.1 to 0.5 mm. Preferably, the injection amount of the electrolytic solution is in a range of 0.1 to 10% of the void volume in the electrode.
