EXTERIOR MATERIAL FOR ALL-SOLID-STATE BATTERY, METHOD FOR MANUFACTURING SAME, AND ALL-SOLID-STATE BATTERY

An exterior material for an all-solid-state battery, wherein hydrogen sulfide generated inside the all-solid-state battery including a sulfide solid electrolyte material is effectively suppressed from leaking to the outside. The exterior material for an all-solid-state battery is used for an all-solid-state battery including a sulfide solid electrolyte material, and is composed of a laminate having: at least a substrate layer; a barrier layer; and a heat-fusible resin layer in this order from the outside, wherein the amount of hydrogen sulfide permeation through the resin constituting the heat-fusible resin layer is 1.0×10cc·mm/cm·sec·cmHg or less.
