Sulfide solid electrolyte material, battery, and method of manufacturing sulfide solid electrolyte material

A sulfide solid electrolyte material, comprising an element M1, an element M2, an element M3 and an element S, wherein:

• the element M1 is at least one selected from the group consisting of Li, Na, K, Mg, Ca and Zn, and contains at least one of Li or Na;
• the element M2 is at least one selected from the group consisting of P, Sb, Si, Ge, Sn, B, Al, Ga, In, Ti, Zr and V, and contains at least P;
• the element M3 is at least one selected from transition elements of group 3 to group 12;
• and
• the sulfide solid electrolyte material has a peak at a position of 2θ=29.58°±0.50°, in X-ray diffraction measurement using a CuKα beam, or
• the sulfide solid electrolyte material does not have a peak at a position of 2θ=27.33°±0.50°, in X-ray diffraction measurement using a CuKα beam, or
• in a case in which the sulfide solid electrolyte material has a peak at a position of 2θ=27.33°±0.50°, if a diffracted intensity of the peak at 2θ=29.58°±0.50° is IA and a diffracted intensity of the peak at 2θ=27.33°±0.50° is IB, a value of IB/IA is less than 1.00.
