Abstract: A fully-solid-state battery packaging material includes at least a substrate layer, a barrier layer, and a sealant layer in this order. The moisture content of the sealant layer is 2700 ppm by mass or less. The sealant layer is, for example, a polyolefin film containing a polyolefin-based resin or a polyester film containing a polyester-based resin.
