Abstract
The battery packaging material includes a substrate layer, a heat-fusible resin layer, a barrier layer arranged between the substrate layer and the heat-fusible resin layer, and a substrate protective layer as an outermost layer arranged on an outer side of the substrate layer. The substrate protective layer includes a binder resin, wax as solid fine particles, resin beads, and inorganic fine particles, and a gross value of the surface of the substrate protective layer is 1% and 5%.
