PROBLEM TO BE SOLVED: To provide a method for easily producing a sulfide solid electrolyte having high purity and high ionic conductivity because side reactions and the like are unlikely to occur. SOLUTION: A method for producing a sulfide solid electrolyte containing a lithium atom, a sulfur atom, a phosphorus atom and a halogen atom, and a complex (1) containing a sulfide containing a lithium atom, a sulfur atom and a phosphorus atom as a constituent element. A sulfide solid electrolyte, comprising preparing a complex (2) containing a halide containing a lithium atom and a halogen atom as a constituent element, and mixing the complex (1) and the complex (2), respectively. Manufacturing method. [Selection diagram] None |
