摘要： PROBLEM TO BE SOLVED: To provide a method of eliminating the leakage of a electrolyte solution of an electric double-layer capacitor in a structure that an electrolyte is impregnated into a laminate formed by winding in spiral the laminate of polarizing electrode, current collecting material and separator, and the laminate is then sealed into a case, the opening end thereof is sealed with a cap composed of an elastomer, and a lead connector to the current collecting material is protruded to the outside through the cap. SOLUTION: A sloping area is provided to a part of the side surface of the cap and the external diameter of only this portion is set larger than the internal diameter of a case. Accordingly, when the cap is inserted to the case, the function as a packing is improved by loading stress to the cap. Since the external diameter of the cap is larger than the internal diameter of the case only at a part thereof, working efficiency is never deteriorated in a sealing process.
