    • PROBLEM TO BE SOLVED: To provide a method for producing an aliphatic saturated carboxylic acid, by which the unsaturated bond of an aliphatic unsaturated carboxylic acid or an aliphatic olefin-based hydrocarbon is cleft by using only a solid oxidation catalyst and a molecular oxygen-containing gas without using a peroxide so as to produce a corresponding aliphatic saturated monocarboxylic acid and aliphatic saturated dicarboxylic acid. SOLUTION: The method for producing an aliphatic saturated carboxylic acid comprises carrying out reaction in a solvent-free condition by using a transition metal skeleton-substituted type zeolite catalyst in oxidatively cleaving an aliphatic unsaturated carboxylic acid or an aliphatic olefin-based hydrocarbon with a molecular oxygen-containing gas to produce a corresponding aliphatic saturated monocarboxylic acid and/or aliphatic saturated dicarboxylic acid. In the production method, the reaction is advanced in a liquid phase or vapor phase under mild conditions of a low temperature and low pressure to produce the objective substance in a high reaction conversion and in high selectivity.
