Nonaqueous electrolyte battery

Disclosed is a nonaqueous electrolyte battery including a battery element contained in an outer covering member composed of a laminated film and sealed therein by heat seal, and a gas absorbable material interposed between the outermost layer of the outer covering member and the battery element. Such a battery is advantageous in that even if gas occurs in the battery element, the laminated film as the outer covering member is prevented from being swelled.
