The main purpose of the present invention is to provide a solid electrolyte microparticle production method capable of stably producing solid electrolyte microparticles having a minute particle diameter. In the present invention, the abovementioned problem is solved by providing a solid electrolyte microparticle production method characterized by comprising: a preparation step of preparing a solid electrolyte solution by dissolving a solid electrolyte material in a good solvent; and a precipitation step of precipitating solid electrolyte microparticles by mixing the solid electrolyte solution into a poor solvent in which the solid electrolyte material is less soluble than in the good solvent, and characterized in that in the precipitation step, the solid electrolyte solution is mixed into the poor solvent such that in the mass ratio (m:n) between the mass (m) of the solid electrolyte solution and the mass (n) of the poor solvent, the rate of the mass (n) of the poor solvent is higher than that in a mass ratio at which the solid electrolyte microparticles are precipitated. |
