成したことを特徴とする防爆型電池。The opening of the battery case is sealed with a terminal plate that also serves as a lid via a sealing gasket, and a thin wall portion that is easily broken by gas pressure inside the battery case is formed in a part of the wall of the sealing gasket. In an explosion-proof battery in which a gas vent hole is formed in the terminal plate at a position opposite to the thin-walled portion, the circumference of the thin-walled portion is formed on the side of the sealing gasket facing the terminal plate. A protrusion is integrally formed in the surrounding portion, and the protrusion maintains a gap between a portion of the sealing gasket near the thin wall portion and a portion of the terminal plate near the gas vent hole. An explosion-proof battery characterized by:
