Cylindrical battery cell with non-aqueous electrolyte

The sealing performance of a secondary battery cell using a non-aqueous electrolyte is increased. In an annular swaged space (65) of a battery cell container (60), a sealing lid (50) is swaged and fixed by an insulated sealing ring (43) composed of a full fluorine series fluorine resin and an opening end (60a) of the battery cell container is sealed and the sealing lid is electrically insulated from the battery cell container. The opening end of the battery container is subject to swaging to compress the insulated sealing ring in the way of cramping two surfaces of a flange unit (50F) of the sealing lid, so as to form sealing surfaces on the two surfaces of the flange unit. The upper, lower surfaces of the flange unit are closedly adhered on the insulated sealing ring and pressed by the inner surface of the battery cell container deformed by swaging from above and bottom. In the insulated sealing ring, compression points (1A,1B) with great compression force are generated on the upper, lower surfaces of the fl
