The object of the present invention is to produce cycloalkanol and/or cycloalkanone with good selectivity by oxidizing cycloalkane with molecular oxygen. The method of the present invention comprises the step of oxidizing cycloalkane with molecular oxygen in the presence of cobalt salt of carboxylic acid and cobalt complex with porphyrin as a ligand; such cobalt complex typically represented by the formula (1):
