Claims

[Scope of utility model registration request]

The electric double layer capacitor element laminate is housed in a conductive case, and the laminate is assembled into an assembled electrode in which a first electrode plate and a second electrode plate each having a lead terminal are arranged on the upper and lower surfaces of an inner case made of an insulating material. In an electric double layer capacitor in which the outer edge of the conductive case is caulked into a curled shape by maintaining a predetermined pressing force, the outer diameter of the first electrode plate is smaller than the outer diameter of the inner case, An electric double layer capacitor characterized in that a tapered chamfered portion is provided on the upper part outside the inner case.
