PROBLEM TO BE SOLVED: To produce cyclohexanone oxime at a low cost by reducing a catalyst cost in the the ammoximation of the cyclohexanone. SOLUTION: This method for producing the cyclohexanone oxime comprises (1) a process of ammoximating cyclohexanone with hydrogen peroxide and ammonia in the presence of a titanosilicate and a silicon compound other than the titanosilicate, and (2) a process of calcining the titanosilicate used in the process (1) under an atmosphere of an oxygen-containing gas, and using the titanosilicate calcined in the process (2) in the process (1).
