Claims

[Scope of utility model registration request]

In a cylindrical battery in which a cathode mixture, a separator, and an anode mixture are placed coaxially with each other in a cylindrical battery can, the separator includes at least a single separator element cut into strips, It is formed into a multilayered cylindrical shape consisting of an inner layer part and an outer layer part 1, and its lower end opening is closed with an electrically insulating filler layer to form a bottom part, and the outer peripheral edge of the filler layer is The lower ends of the inner layer and the outer layer of the multi-layer wound cylindrical separator are fixed to each other by the lower end difference means at the lower ends of the inner layer and the outer layer of the multi-layer wound cylindrical separator. A cylindrical battery characterized by being integrated.
