A fullerene mixture comprising any two or more of C60, C70 and higher fullerenes having greater than 70 carbon atoms is brought into contact with an amine having two or more nitrogen atoms, especially an amine having an amidine structure, in a solvent to form a complex of a specific fullerene contained in the fullerene mixture and the amine, and the complex is separated from a solution in which fullerenes not forming the complex are dissolved. Consequently, a method of fullerene separation, by which the specific fullerene is separated from the fullerene mixture with ease and at low cost, and the complex having the fullerene can be provided.
