PROBLEM TO BE SOLVED: To provide a method for producing a dispersion liquid of flake-type graphite, for achieving efficient production of a dispersion liquid of flake-type graphite, in which flake-type graphite is stably dispersed. SOLUTION: The method comprises mixing a graphite compound having a sulfur-containing group, a nitrogen compound selected from a group consisting of primary amines, hydrazine and ammonia, and water, to prepare a mixture liquid having a pH of 8 to 14, and granulating the graphite compound into flakes. By the method, a dispersion liquid of flake-type graphite having stably dispersed flake-type graphite can be efficiently produced by peeling layer faces from each other of the graphite compound.
