Abstract: A nonaqueous electrolyte battery is disclosed which is capable of improving impact resistance while airtightness of a laminate film is being maintained. When a battery element is accommodated in a casing constituted by a laminate film and the case is welded to enclose the battery element, a resin layer is provided for at least one surface of a battery element. The resin layer may be a resin plate which has previously been molded or the resin layer may be formed by enclosing resin. The resin layer is provided for two sides of all of the sides of the battery element which have smallest areas. In a case of a wound-type battery element, the resin layer is provided for the two end surfaces of the wound battery element. The resin layer has a shock buffering function to protect the battery element from impact.
