To provide a method for producing a cycloalkylalkylamine compound, capable of industrially advantageously producing the compound useful as a raw material for a medicament and an agrochemical, a raw material for a liquid crystal, an amidating agent in organometallic reaction, a corrosion inhibitor, etc., in a high yield.

This method for producing the cycloalkylalkylamine compound expressed by formula (2) (R2 and R3 are each a 1-6C aklyl or a 4-10C cycloalkyl, provided that at least one of R2 and R3 is a 4-10C cycloalkyl) comprises conducting catalytic hydrogenation reaction of a 4-10C cycloalkanone with an amine compound expressed by formula (1) (R1 is a 1-6C alkyl, a 4-10C cycloalkyl or H) in the presence of a catalyst of a metal belonging to the 8 to 10 groups in the long periodic table.
