PROBLEM TO BE SOLVED: To provide a method for producing a homogeneous and high purity composite metal sulfide containing two or more kinds of metals and being expected to be applied in wide fields such as a thermoelectric conversion material, a coloring pigment, a superconducting material and the like. SOLUTION: In the method for producing the composite metal sulfide containing at least two kinds selected from the metal group consisting of an alkali metal, an alkaline earth metal, a transition metal and the like, a metal salt forming the composite metal sulfide is dissolved in a glycol solution added with a hydroxy acid and heated to gelate or pulverize, an oxycarbonate, a composite metal oxide or a mixture containing these is produced by firing and then product is treated under a gas atmosphere containing a sulfur compound.
