  "textContent": "For avoiding problems in existent non-aqueous electrolyte cells or electric double layer capacitors of a rectangular parallel piped shape that sealing at high reliability can not be attained unless a bonded portion has a sufficient margin of a certain degree in view of liquid electrolytes contained therein, a metal layer comprising a metal ring and a brazing material having a heat expansion coefficient approximate to that of a concave vessel of a non-aqueous electrolyte cell or an electric doceble layer capacitor is disposed to the edge of the vessel, a sealing plate made of a metal having a property similar with the metal ring and having a brazing material layer at the bonded surface is also used for the sealing plate and, further, paired electrodes comprising a positive electrode and a negative electrode, a separator and an electrolyte are contained in the concave vessel, the sealing plate is placed on the vessel and seam welding is conducted by using a parallel seam resistance welding method thereby capable of attaining sealing at high reliability.",
