PROBLEM TO BE SOLVED: To provide a method for producing a saturated hydrocarbon solution of fullerene capable of preparing a saturated hydrocarbon solution in which fullerene is stably dissolved at a high concentration.SOLUTION: The saturated hydrocarbon solution in which fullerene is dissolved is prepared by dissolving fullerene in toluene or cyclohexane in advance, mixing this solution with saturated hydrocarbon, and distilling off toluene or cyclohexane from the mixed solution under reduced pressure.
