Abstract: The present invention addresses a problem of providing a production method for a sulfide solid electrolyte having a high ionic conductivity by pulverizing a sulfide solid electrolyte without complicating the production process. Provided is a production method for a crystalline sulfide solid electrolyte including mixing a raw material inclusion containing at least one selected from a lithium atom, a sulfur atom and a phosphorus atom, and a complexing agent without using a mechanical treating machine to obtain an electrolyte precursor, heating the electrolyte precursor to obtain a complex degradate, performing smoothing treatment on the complex degradate to obtain a smoothed complex degradate, and heating the smoothed complex degradate.
