Abstract

PURPOSE:To open an air hole without damaging components in a battery after sealing the opening of the battery by providing thin wall part for knock down at the opening position of a air hole of positive electrode case. CONSTITUTION:A thin wall portion 12 to be punched is formed in a position on a positive electrode case 4 where an air hole 8 for taking oxygen in air as a positive electrode active substance into a battery is to be opened after sealing the opening of the battery. By providing such a thin wall portion 12 for such a purpose, the components in the battery are not damaged even if the air hole 8 is opened by punching after sealing the opening of the battery.
