Claims

[Scope of Claim for Utility Model Registration] An exterior can that also serves as a unipolar terminal with a built-in power generation element, a metal lid that is fitted and fixed to the opening edge of the exterior can, and insulating packing in the through hole provided in the metal lid. and a terminal member of the other polarity fixed through the metal lid, and a non-circular recess is formed at the periphery of the through hole on at least one of the upper and lower surfaces of the metal lid, and A sealed battery characterized in that an extension of the insulating packing located within the recess has a shape that cannot rotate within the recess. The recess is formed on one surface of the metal lid, and a protrusion corresponding to the recess is formed on the other surface, and the insulating packing is formed by insert molding, and the metal lid An extension of the insulation packing on one surface of the metal lid is in contact with an inner wall of the recess, and an extension of the insulation packing on the other surface of the metal lid extends beyond the protrusion. Sealed battery. The other polarity terminal member is composed of a support portion and a flat plate portion formed at one end of the support portion, and radial projections are formed on the lower surface of the flat plate portion, and the projections bite into the opposing insulating packing. A sealed battery according to the claim.
