Claims

[Claims for Utility Model Registration] 1- A power generation element using an alkaline electrolyte is placed in a flat metal battery case that also serves as an impulse terminal, and one pole of the power generation element is brought into contact with the case. , the other pole is brought into contact with the outer surface of the dish-shaped current collector plate, and the inner surface of the dish-shaped current collector plate is passed through the inside and outside of the case and from the case through a hermetic sealing material. An insulator is welded and connected to a current collector lead that is held insulated and also serves as a terminal for external force, and further, an insulator is provided to insulate and isolate the periphery of the opening of the dish-shaped current collector plate from the case and the other seed material. In a flat sealed battery in which the inside of the dish-shaped current collector plate is isolated from the power generation element by joining the plate-shaped current collector plate to a material portion, the joint portion between the opening periphery of the current collector plate and the insulating material portion and the surrounding area. A flat sealed battery characterized by having a seal layer made of a liquid sealant formed into an annular shape. 2. The sealing layer portion is filled in an annular groove formed in the joint surface of the insulating material portion with the opening peripheral portion of the current collector plate, and is formed from a liquid sealant. Flat sealed battery. 3. The flat seal according to claim 1, wherein the sealing layer portion is formed of a liquid sealing agent attached in an annular manner to the joint surface of the insulating material portion with the opening peripheral portion of the current collector plate. type battery. 4. The flat sealed battery according to claim 1, 2, or 3, wherein a liquid sealant with relatively high viscosity and high adhesiveness is used as the liquid sealant.
