description	A method for producing bis(aminomethyl)cyclohexane, including hydrogenating xylylenediamine in the presence of a solvent and a catalyst, wherein the catalyst with decreased activity due to use is treated in a catalyst regeneration treatment step including the following step (1) and step (2), and then reused in a reaction system: step (1): maintaining an amount of bis(aminomethyl)cyclohexane in a liquid before the step (2) at 20% by mass or less, step (2): heating the catalyst to 100 to 500°C and bringing the catalyst into contact with a hydrogen-containing gas.
