Abstract

The object of the present invention is to provide a sealed battery that includes a gas release valve formed on the closure cap by covering a gas release hole with a thin film that rarely breaks even if the battery is dropped. For this object, the external casing of the sealed battery includes a shielding member passing no drop of the electrolyte between the thin film and the generator element so as to form a gas channel from the internal space of the external casing to the gas release hole. When the sealed battery is dropped, electrolyte drops are pushed out of the generator element at the side opposed to the thin film. The thin film, however, is prevented from being directly hit by the drops due to the presence of the shielding member.
