In manufacturing aromatic hydrocarbons by causing a contact reaction between a lower hydrocarbon and a catalyst, the aromatic hydrocarbons are stably produced over a long period of time while maintaining high aromatic hydrocarbon yields. The process includes a reaction process of initiating the contact reaction between the lower hydrocarbon and the catalyst thereby obtaining the aromatic hydrocarbons and hydrogen, and a regeneration process of regenerating the catalytic activity by bringing hydrogen into contact with the catalyst used in the reaction process. The reaction process and the regeneration process are repeated thereby producing the aromatic hydrocarbons and hydrogen. In the reaction process, carbon monoxide is added to the lower hydrocarbons and additionally a reaction temperature is set at higher than 800° C.
