A method for producing solid electrolyte microparticles includes steps of: 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 whose solubility to the solid electrolyte material is lower than that of the good solvent, wherein 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 proportion of the mass “n” of the poor solvent is increased to adjust the mass ratio to be higher than or equal to the mass ratio at which the solid electrolyte microparticles are precipitated. |
