As a packaging material applied to an all-solid-state battery using a solid electrolyte containing a sulfide solid electrolyte material, even when the all-solid-state battery is constrained in a high-pressure state, deterioration of the barrier layer of the packaging material is effectively suppressed, and Provided is an all-solid-state battery exterior material capable of discharging hydrogen sulfide generated inside the all-solid-state battery to the outside. At least from the outside, a sulfide solid electrolyte material comprising a laminate comprising a substrate layer, a barrier layer, a barrier layer protective film formed on the surface of the barrier layer, and a heat-fusible resin layer in this order An all-solid-state battery packaging material for use in an all-solid-state battery, wherein a hydrogen sulfide permeation amount of a resin constituting the heat-fusible resin layer is 1.0×10 -8 cc·mm/cm 2 ·sec·cmHg or more, an all-solid-state battery packaging material . |
