Abstract
Provided is a more appropriate method of producing lithium sulfide having high ionic conductivity and no by-products generated. The method of producing lithium sulfide includes a temperature rising step (Step S14) of reducing lithium sulfate fed into a furnace in a state of heating to a temperature of more than 700° C. under an atmosphere of a reduced pressure of 0.05 MPa or less.
