Claims

[Scope of Claim for Utility Model Registration] 1. A power generation element consisting of a positive electrode mixture, a separator, and a gelled negative electrode arranged concentrically in sequence is housed in a cylindrical battery can, and the opening of the battery can is connected to the negative electrode terminal. A negative electrode current collector rod is formed by combining a plate and sealing packing, one end of which is buried in the gel negative electrode, and the other end of the negative electrode current collector rod is electrically connected to the inner surface of the negative electrode terminal plate via a positive temperature coefficient thermistor material. A cylindrical alkaline battery characterized by: 2. The cylindrical alkaline battery according to claim 1, further comprising a conductive leaf spring interposed between the inner surface of the negative electrode terminal plate and the thermistor material.
