PURPOSE:To synthesize C60 at a lowered production cost by using a specific atmospheric pressure discharge device, adding a carbon raw material gas to a rare gas in a discharged state, producing the C60 with the energy of the discharged state, and subsequently depositing the produced C60 on a substrate. CONSTITUTION:An Ar/He rare gas mixture is charged at a prescribed flow rate into an atmospheric pressure discharge device in which a cylindrical dielectric substance such as quartz glass is placed between a central electrode such as a W electrode and an outside electrode such as a stainless steel electrode, both being placed in a coaxially cylindrical shape. A high frequency electric power is applied to the flow of the gas from a high frequency electric source to produce the rare gas of a stable plasma discharge state having a temperature of =1000 K. A carbon raw material such as vaporized naphthalene is charged together with a carrier gas such as Ar into a discharge space at the tip of the central electrode and kept for a prescribed time. A substrate such as a borosilicate glass plate is placed at the tip of the cylindrical dielectric substance to deposit the product on the substrate. After the finish of the reaction, the resultant product is extracted with hexane, etc., to provide the C60.
