PURPOSE:To provide the device for easily synthesize fullerene at a high yield. CONSTITUTION:An evaporating carbon rod 1 having a diameter within 1mm and a counter electrode carbon rod 2 having the diameter of =2 times this diameter are brought into contact with each other. The circumference of the carbon rods 1, 2 is enclosed by a cylinder 20. Two holes facing each other are provided on the cylinder 20. The one of these holes is used as a helium introducing port 4 and the other as a suction port 5a for collecting the formed carbon powder. The suction port is differentially discharged and the carbon powder gathers at the collector 6. The carbon rods 1, 2 are heat under resistance to evaporate the carbon from the carbon rod 1. Since just two holes are bored at the cylinder 20, the smooth flow of the carbon vapor from the introducing port 4 side to the suction port 5a side is generated. More than 85% of the consumed carbon rod 1 is, therefore, collected as the carbon powder in the collector. More than 15% in the recovered carbon powder is the fullerence (C60, C70). Since the diameter of the evaporating carbon rod 1 is confined to =1mm, there is no need for a large-capacity power source.
