Abstract

PURPOSE:To improve leak-proof performance by forming a projection on the inner face of rising wall of circular gasket. CONSTITUTION:A portion of electrolyte is injected into the bottom of anode can 9 to mount anode agent 10 and separator 11 then cathode agent 13 contained in cathode terminalboard 1 is provided on them. A circular gasket 3 is placed on said terminalboard 1 to enclose the opening 12 of anode can 12 to form a button-type cell. The circular gasket 3 of said cell is made of synthetic resin such as polyethylen or rubber having approximately L-shaped cross-section comprised of bottom wall 4 and rising wall 5. While furthermore a projection 6 is provided on the rising wall 5 to be located above the upper end 7 of circumferential folding portion 2 of cathode terminalboard 1.
