PRODUCTION METHOD FOR ELECTRODE MEMBER

A method for producing an electrode member that configures an electrode body of an all-solid-state battery, including: a slurry preparation step for preparing a mixed material slurry that contains at least a binder, solid electrolyte particles, and a nonaqueous solvent with low polarity; a molding step for molding the mixed material slurry into a desired shape; and a drying step for obtaining a molded body by removing the nonaqueous solvent with low polarity from the mixed material slurry after the molding. Then, the temperature of the mixed material slurry is controlled so as not to cause re-crystallization of the binder, which has been dissolved in the nonaqueous solvent with low polarity, at least until the initiation of the molding step. Consequently, it is possible to stably provide an all-solid-state battery that has low battery resistance, while improving electrode member production efficiency by preventing gelation of a mixed material slurry.
