PURPOSE: To provide the method for producing theε-caprolactam useful on industry, enabling to produce theε-caprolactam not inferior to the conventional quality at a low cost. CONSTITUTION: The method for producing theε-caprolactam by hydrating cyclohexene, subjecting the obtained cyclohexanol to a dehydrogenation reaction, reacting the obtained cyclohexanone with hydroxylamine and subsequently subjecting the obtained cyclohexanone oxime to a Beckmann rearrangement, is characterized by reducing indene compounds contained in the cyclohexanol fed to the dehydrogenation reaction to <=15ppm.
