A main object of the present invention is to provide a solid electrolyte material having excellent Li ion conductivity. To attain the object, the present invention provides a solid electrolyte material represented by a general formula: Lix(La2−aM1a)(Ti3−bM2b)O9+δ, characterized in that “x” is 0<x≦̸1; “a” is 0≦̸a≦̸2; “b” is 0≦̸b≦̸3; “δ” is −2≦̸δ≦̸2; “M1” is at least one selected from the group consisting of Sr, Na, Nd, Pr, Sm, Gd, Dy, Y, Eu, Tb, and Ba; and “M2” is at least one selected from the group consisting of Mg, W, Mn, Al, Ge, Ru, Nb, Ta, Co, Zr, Hf, Fe, Cr, and Ga. |
