The object is to produce an aromatic compound (particularly, benzene) from a lower hydrocarbon having 2 or more carbon atoms (particularly, an ethane-containing gas composition such as ethane gas or natural gas) in the presence of a catalyst in a stable manner. Thus, disclosed is a process for production of an aromatic compound comprising the step of reacting ethane or an ethane-containing raw gas in the presence of a catalyst. The catalyst may comprise molybdenum supported on a metallosilicate such as H-type ZSM-5H or H-type MCM-22. In the reaction, the reaction temperature may fall within the range from 550 C to 750 C exclusive, preferably within the range from 600 C to 680 C inclusive, and the raw gas may additionally contain methane or hydrogen, thereby improving the production efficiency or stability.
