PROBLEM TO BE SOLVED: To provide a method for efficiently and easily separating fullerene 60 or 70 with high purity from a mixture of fullerenes including fullerene 60 and 70 as the main components. SOLUTION: In the method for separating fullerene 60 or fullerene 70 with high purity from a mixture of fullerenes including fullerene 60 and fullerene 70 as the main components, a solvent used is set, the fullerene mixture is added at the reflux temperature of the solvent to the solvent in an amount 0.8-1.2 time the amount (volume) of the solvent in which a fullerene which accounts for a minor proportion in the fullerene mixture is dissolved to form a saturated solution, and the solvent is refluxed, cooled and filtered to separate insoluble matter, whereby a fullerene which accounts for a major proportion in the fullerene mixture is separated with high purity from the fullerene mixture.
