Abstract
A non-aqueous electrolyte battery includes a positive electrode, a negative electrode and an electrolytic solution sealed in a sealing bag, from which lead wires of the positive electrode and the negative electrode are extended to the outside, and the lead wires are also sealed. The battery maintains reliability in hermetic property during long term use. The sealing type non-aqueous electrolyte battery is characterized in that an acid-modified polyethylene, an acid-modified polypropylene or an ionomer is used as a plastic layer of the sealing bag, and preferably both the function of preventing the transmission of water and the function of preventing the transmission of an acid are provided by the plastic layer.
