PROBLEM TO BE SOLVED: To provide a method for producing an amine by a reaction in the presence of a catalyst using a nitrogen compound selected from ammonia, a primary and a secondary amines and hydrogen. SOLUTION: A catalytically active composition of a catalyst after the production and prior to the treatment with hydrogen comprises 22-45 mass % of an oxygen-containing compound of zirconium, 1-30 mass % of an oxygen-containing compound of copper and 5-50 mass % of an oxygen-containing compound of nickel in >1 molar ratio of nickel to copper and further comprises 5-50 mass % of the oxygen-containing compound of cobalt calculated as CoO, 0-5 mass % an oxygen-containing compound of molybdenum and 0-10 mass % of an oxygen-containing compound of the calculated aluminum and/or manganese. Thereby, the economical efficiency of a conventional method is improved and the amine is produced by a technically simple method which can be carried out with a high aldehyde conversion rate and a high ketone conversion rate, a high yield, a high selectivity, a high catalyst useful life and a high mechanical stability of a catalyst molded product.
