Abstract: There is provided an inorganic solid electrolyte-containing composition containing an inorganic solid electrolyte, a polymer binder, and a dispersion medium, in which the polymer binder includes a polymer having a tensile permanent strain of less than 50% in a stress-strain curve obtained by repeating pulling and restoration once and includes a polymer binder in which the adsorption rate with respect to the inorganic solid electrolyte in the dispersion medium is less than 60%. There are also provided a sheet for an all-solid state secondary battery and an all-solid state secondary battery, in which this inorganic solid electrolyte-containing composition is used, and manufacturing methods for a sheet for an all-solid state secondary battery, and an all-solid state secondary battery.
