PROBLEM TO BE SOLVED: To provide a fullerene production method capable of selectively forming fullerene C60, fullerene C70, or a higher fullerene. SOLUTION: In a method for producing mixed fullerene having fullerene C60, fullerene C70, and higher fullerenes by feeding a hydrocarbon raw material and an oxygen-containing gas into a reactor 11 and subjecting them to incomplete combustion or thermal decomposition in the reactor 11, the ratio (fullerene C70)/(fullerene C60) in the mixed fullerene is 1 or smaller, the ratio of the fullerene C60, the fullerene C70 and the higher fullerenes produced is controlled, and a sootlike material containing the mixed fullerene is continuously recovered from a high-temperature gas generated in the reactor 11.
