Abstract
A method for producing a sulfide-based solid electrolyte includes heating and melting a raw material under a gas atmosphere containing a sulfur element. The raw material includes a lithium source obtained by using an aqueous solution containing Li and SO4, and a ratio of SO4 to Li is 0.1 mol % or more in the aqueous solution.
