Abstract

A polymer battery module packaging sheet includes, as essential components, a base layer (61), an aluminum layer (62), chemical conversion coatings (64a, 64b) coating the opposite surfaces of the aluminum layer (62), and an innermost layer (63). The chemical conversion coatings (64a, 64b) are formed by processing the opposite surfaces of the aluminum layer (62) by a phosphate treatment method. The base layer (61) and the innermost layer (63) are bonded to the chemical conversion coatings (64a, 64b) of the aluminum layer (62) with adhesive layers (65a, 65b), respectively.
