A non-aqueous battery comprises a positive electrode, a negative electrode and a non-aqueous electrolyte as well as a battery can serving as a negative electrode-terminal and a sealing terminal serving as a positive electrode-terminal which are crimp-sealed through a gasket comprising a polyolefin resin, wherein the polyolefin resin comprises a block copolymer of propylene and ethylene having an ethylene copolymerization rate ranging from 2 to 20% by weight and a modulus in flexure ranging from 12000 to 18000 kg/cm2. The non-aqueous battery has substantially improved storage stability when it is not in use and is not deteriorated even when it is subjected to discharge, large current discharge and pulse-discharge in an atmosphere whose temperature varies. |
