A solid electrolyte material that does not generate hydrogen sulfide and has high ionic conductivity is provided. A solid electrolyte material is a compound represented by the following general formula, The cation ratio (M1/Li+M1), which is the content ratio of the M1 element to the total amount of the Li element and the M1 element in the general formula (Chemical Formula 1), is more than 0 and 0.07 or less. A solid electrolyte material was used. [Chemical 1] (The M1 element in the formula contains at least one selected from the group consisting of Na, K, Rb, Cs and Fr. The M2 element includes at least one selected from the group consisting of Cl, Br, I and F x in the formula is a real number greater than 0 and less than 3.) [Selection drawing] Fig. 1 |
