PROBLEM TO BE SOLVED: To cut down time, space for manufacturing, cost or the like by conducting processes of powdering of a raw material of the metal sulfide powder, of mixing, pulverizing and synthesizing of a raw material, and of pulverizing or the like of the produced metal sulfide, at one time. SOLUTION: The manufacturing time, space, cost or the like can be cut down by charging pulverizing balls, metal lumps and sulfur lumps both having an optional shape and dimension into the inside of a pulverizing vessel body, and heating the inside of the vessel body while closing the vessel body or passing an inert gas through the vessel body and operating the pulverizing vessel, because the processes of mixing, pulverizing and synthesizing of a raw material, and of pulverizing of the produced metal sulfide can be conducted at one time.
