Abstract
According to the present disclosure, there is provided a sealing plate equipped with a gas discharge valve that reduces processing load and work hardening during molding. A gas discharge valve of a sealing platedisclosed herein has a flat plate-shaped base portion and a protruding portion protruding from a first surface of the base portion in a first direction, an annular thin-walled portion having a thickness smaller than the thickness of the protruding portion is provided around the protruding portion, and a first surface of the thin-walled portion is substantially on the same surface as the first surface of the base portion. In the gas discharge valve having the above configuration, the total amount of metal that is plastically deformed is reduced by limiting the formation region of the thin-walled portion to the periphery of the protruding portion.
