Abstract: Provided is a method of manufacturing a positive electrode for a solid-state battery, the method including: a step of mixing a positive electrode active material, a sulfide solid electrolyte, a binder, and a solvent with each other to prepare a positive electrode slurry; a step of applying the prepared positive electrode slurry to a surface of a solid electrolyte layer of the solid-state battery or a substrate of the positive electrode; and a step of drying the applied positive electrode slurry. In this method, the solvent is butyl butyrate, and the binder is a copolymer containing a vinylidene fluoride (VDF) monomer unit and a hexafluoropropylene (HFP) monomer unit, in which a molar ratio of the HFP monomer unit to a total amount of the VDF monomer unit and the HFP monomer unit is 10% to 20%.
