Claims (1)

[Scope of Claim for Utility Model Registration] 1. A power generation element made by spirally winding a group of sheet-like electrodes in which a positive electrode, a separator, and a negative electrode are stacked in sequence, is placed inside a cylindrical battery can with an insulating plate arranged at the bottom. In a battery housed in a battery, a thin plate having an outer diameter approximately the same as the inner diameter of the battery can is provided between the insulating plate and the inner bottom surface of the battery can, and a thin plate having an outer diameter approximately the same as the inner diameter of the battery can, and a A battery characterized in that a lead plate is pressed into contact with the inner peripheral surface of a battery can by this thin plate. 2. The battery according to claim 1, wherein the lead plate and the thin plate are integrally formed, and the outer periphery of the thin plate portion is crimped to the inner peripheral surface of the battery can.
