The present invention provides a composition for forming an active material layer comprising a sulfide-based solid electrolyte, a method for producing the same, and a method for producing a solid electrolyte-containing sheet and an all-solid-state secondary battery. Active material, conductive aid containing carbonaceous material, and dispersion medium, in the composition for forming an active material layer, the dispersion medium contains at least one carbonyl group bonded to two aliphatic groups having 4 or more carbon atoms. Ketone compound dispersion medium. |
