A main object of the present disclosure is to provide a method for producing an all-solid-state battery in which the used amount of the PVDF binder may be decreased, and the deterioration of the sulfide solid electrolyte may be suppressed. The present disclosure achieves the object by providing a method for producing an all-solid-state battery, the method comprising a step of forming an electrolyte-containing layer by using a slurry including a sulfide solid electrolyte containing a Li element, a P element, and a S element, a PVDF binder, and a solvent, and as a first solvent, the solvent includes 50 volume % or more of a ketone solvent represented by a general formula (1): n n n n n n n n n n n n wherein, in the general formula (1), R 1 and R 2 are each independently a saturated hydrocarbon group or an aromatic hydrocarbon group, and a carbon number of at least one of R 1 and R 2 is 2 or more. |
