Provided is a novel sulfide-type solid electrolyte of which the electric conductivity can be significantly improved compared with those of conventional solid electrolytes. Proposed is a sulfide-type solid electrolyte comprising a compositional formula: Li7+xP1-ySiyS6 (wherein x is -0.6 to 0.6 and y is 0.1 to 0.6) which has the structural skeleton of Li7PS6 and in which some of P's are substituted by Si. |
