1. A method for producing an electrode member that configures an electrode body of an all-solid-state battery, comprising:
a slurry preparation step that prepares a mixed material slurry which comprises at least a binder, a solid electrolyte particle, and a low polarity nonaqueous solvent;
a molding step that molds the mixed material slurry in a desired shape; and
a drying step that removes the low polarity nonaqueous solvent from the molded mixed material slurry so as to obtain a molded body, wherein
in a case where a melt starting temperature of the binder is represented as Tm and a maximum temperature of the mixed material slurry is represented as Tmax, the temperature of the mixed material slurry is controlled, at least until the molding step is started, to satisfy following Formula (1)
Tmax≤Tm  (1).
