摘要：
The present invention can provide a production method for a solid electrolyte having Li3PS4, said method characterized by including: a solution-making step in which a homogenous solution is prepared by mixing Li2S and P2S5 into an organic solvent; and a precipitation step in which further Li2S is added to and mixed in the homogenous solution and a precipitate is formed. Preferably, the embodiment either has a molar ratio (Li2S/P2S5) between the Li2S and the P2S5 in the solution-making step of 1.0-1.85 or has further Li2S added to the homogenous solution in the precipitation step such that the molar ratio becomes Li2S/P7S5=2.7-3.3.
