A 1st invention provides the battery packaging material by which it has the discrimination from the outside, is excellent in a moldability and insulation, and an appearance defect and a sealing defect were suppressed. A second invention provides a battery packaging material having designability or distinguishing properties, which is excellent in concealability and adhesiveness after molding, and is also excellent in electrolyte resistance and surface insulation properties. The battery packaging material of the first invention includes a laminate in which at least a base layer, an adhesive layer, a metal layer, and a sealant layer are sequentially laminated, and at least one of the base layer and the adhesive layer contains a dye. The battery packaging material of the second invention includes a laminate in which at least a decoration layer, a substrate layer, a metal layer, and a sealant layer are sequentially stacked, wherein the decoration layer includes at least a first decoration layer and a second decoration layer in order from the substrate layer side. It has a decoration layer, the said decoration layer contains a coloring agent and a matting agent, The ratio of resin of each of the said 1st decoration layer and a 2nd decoration layer is 60 mass % or more. |
