<p>PROBLEM TO BE SOLVED: To provide a battery laminate sheath material which can be made lightweight by reducing entire thickness as a sheath material, can be surely adhered to a battery body during thermal adhesion and can be firmly adhered to a plastic component for end portion reinforcement even when using such a component.SOLUTION: One side of an aluminum foil 3 is coated with a base resin, and a first coating layer 1 formed from the base resin is laminated and while leaving exposed edges 1a where the first coating layer is exposed, at both edges of the first coating layer in a width direction on a surface of the first coating layer, a second coating layer 2 is formed from a thermal adhesive resin of which the softening point is 160°C or lower so as to be thermally adhered to a surface film of a battery body.</p> |
