ABSTRACT:
A cylindrical nonaqueous electrolyte solution secondary cell having a high productability and a high sealability is provided. The nonaqueous electrolyte solution secondary cell is a double tube type structure having a spiral electrode laminate structure obtained by spirally winding strip-shaped anode and cathode through a separator around an inner tube between the inner tube and an outer tube. The cell includes a ring-shaped electrically insulating gasket inserted into the inner circumferences of the outer tube at both ends of the inner tube and the outer tube, and first and second ring-shaped sealing plates provided between the inner circumferences of the ring-shaped electrically insulating gasket and the outer circumference of the inner tube. Both the ends are sealed by press-fitting the ring-shaped sealing plates and the inner tube by expanding the inner tube from inside.
