PROBLEM TO BE SOLVED: To improve the yield of fullerenes in the industrial scale production of fullerene by the combustion method, and to sharply decrease the production cost. SOLUTION: In the production of fullerenes by incomplete combustion of hydrocarbon fuel, at least one transition metal compd. selected from the group described below is added as a catalyst to the hydrocarbon fuel and combusted. The group of transition metal compds. includes sandwich-type metallocenes comprised of transition metals and two molecules of cyclopentadiene, complexes of transition metals and ketoenol-type org. active compds. such as acetylacetonate, coordinate compds. of transition metals with amines, olefins, carbon monoxide or the like, chlorides of transition metals, oxides of transition metals and org. carboxylates of transition metals.
