池。[Scope of Claim for Utility Model Registration] (1) A cylindrical battery with a bottom, in which a current collecting rod is used as a wound core, and a spiral electrode body is wound with a separator interposed between both long positive and negative electrodes, together with an electrolyte. In a cylindrical battery that is housed in a container and whose opening is sealed with a sealing plate via an insulating sealing body, the head of the current collector rod is press-fitted or press-contacted in the center between the sealing plate and the current collector rod. a conductive connection plate having a protruding portion that is fitted in the insulating sealing body in the state and having a stepped portion on the peripheral portion that clamps the inner circumferential end of the insulating sealing body between the sealing plate and the insulating sealing body when the insulating sealing body is sealed; A cylindrical battery characterized by an interposed battery. (2) The sealing plate is characterized in that a stepped portion is formed on the outer circumferential portion thereof so that the inner circumferential portion of the insulating sealing body can be held between the conductive connection plate and the utility model registration claim 1. cylindrical battery. (3) The cylindrical shape according to claim 1 of the utility model registration, characterized in that the sealing plate has a safety element interposed between it and the current collector rod, the resistance of which increases rapidly as the temperature rises. battery. (4) The cylindrical battery according to claim 3, wherein the safety element is interposed between the sealing plate and the conductive connection plate.
