PRODUCTION METHOD OF ELECTRODE FOR ALL-SOLID-STATE BATTERIES AND PRODUCTION METHOD OF ALL-SOLID-STATE BATTERY

In a production method of an electrode for all-solid-state batteries, the electrode having an electrode mixture layer containing active material particles and solid electrolyte particles, the solid electrolyte particles include a first group of particles having an average particle diameter d, and a second group of particles having an average particle diameter d. The production method includes: a first mixing step of dry-mixing the active material particles and the first group of particles, to obtain a mixture A; a second mixing step of dry-mixing the mixture A and the second group of particles, to obtain a mixture B; and a pressing step of pressing the mixture B to form the electrode mixture layer. A ratio of the average particle diameter d to the average particle diameter d: d/d satisfies d/d≥1.5.
