Abstract: There are provided an inorganic solid electrolyte-containing composition that exhibits excellent dispersibility and hardly deteriorates an inorganic solid electrolyte and is capable of forming a constitutional layer that exhibits a high ion conductivity even in a low temperature environment, 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. The inorganic solid electrolyte-containing composition contains an inorganic solid electrolyte, a polymer binder, and a dispersion medium, in which the polymer binder contains a polymer having a surface energy of 20 mN/m or less and an SP value of 14 to 21.5 MPa1/2, and the polymer binder is dissolved in the dispersion medium.

Abstract: There is provided an inorganic solid electrolyte-containing inorganic solid electrolyte-containing composition, a polymer binder, and a dispersion medium, where the polymer binder includes a polymer binder consisting of a random polymer that has a halogen atom directly connected to a main chain and has a content of non-aromatic carbon-carbon double bonds of 0.01 to 10 mmol/g. 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, as well as manufacturing methods for a sheet for an all-solid state secondary battery, and an all-solid state secondary battery.
