Abstract
An electric double layer capacitor comprising: activated carbon electrode layers comprising an activated carbon, conductive adhesive layers, a separator, and electrolytic solution comprising non-aqueous solvent and electrolyte between a top vessel and a bottom vessel; in which the top vessel and the bottom vessel are sealed by being caulked with a gasket; in which the activated carbon layers are 0.3 mm or more in a thickness per a layer, not less than 0.55 g/cm3 and not more than 0.8 g/cm3 in an electrode density, and 250% or more in impregnation pickup of electrolytic solution.
