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