Disclosed is a method of manufacture for an aromatic hydrocarbon with long-term stability which preserves high aromatic hydrocarbon yield when manufacturing an aromatic hydrocarbon by catalytic reaction between a lower hydrocarbon and a catalyst. The method comprises: a reaction step wherein the lower hydrocarbon is subjected to a catalytic reaction with a catalyst to produce an aromatic hydrocarbon and hydrogen; and a restoration step wherein the catalytic activity of the catalyst used in the reaction step is restored by subjecting the catalyst to a catalytic reaction with the hydrogen. The reaction step and restoration step are repeated to manufacture aromatic hydrocarbons and hydrogen. In the reaction step, carbon monoxide is added to the lower hydrocarbons and the reaction temperature is higher than 800°C.
