Summary:PURPOSE: A producing method of aromatic amine is provided to form the aromatic amine with the high selectivity, by partially replacing a used catalyst successively or periodically. CONSTITUTION: A producing method of aromatic amine marked with chemical formula 1, comprises a step of hydrogenating a nitro aromatic group marked with chemical formula 2 using hydrogen, on a catalyst arranged in a fixed layer inside a reactor. The catalyst inside the reactor is partially replaced successively or periodically.
