液特性を向上することができる。 The present invention relates to an alkaline battery in which a metal sealing plate also serving as a negative electrode terminal is sealed by caulking an opening of a positive electrode case inward through an insulating gasket made of synthetic resin or synthetic rubber. An alkaline battery, wherein silicone is applied to an exposed portion of an insulating gasket of the assembled battery after sealing, or the silicone is dried and solidified. Incidentally, dimethylsilicone is used as the silicone.

りを力学的に防止できる。According to this structure, since the exposed gasket surface is covered with silicone, it becomes difficult to absorb water from the outside having water repellency, and it is possible to suppress the deterioration of the gasket's creep characteristics due to the water absorption. Further, since the repulsive force of the gasket with respect to the negative electrode terminal at the time of assembling the battery can be maintained, it is possible to dynamically prevent the alkaline electrolyte from rising from the inner surface of the negative electrode terminal.
