    Abstract: The present invention is a method of producing ε-caprolactam through adipamide as an intermediate, and characteristically includes a lactamization step of reacting adipamide, formed from a material compound, with hydrogen and ammonia in the presence of a catalyst containing: a metal oxide mainly containing an oxide(s) of one or more metallic elements selected from the group consisting of metallic elements of group 5 and groups 7 to 14 in the 4th to 6th periods of the periodic table; and a metal and/or a metal compound having a hydrogenation ability. The method can increase the selectivity of ε-caprolactam.
