PROBLEM TO BE SOLVED: To provide a method for evaluating pitting sensitivity that easily evaluates the pitting sensitivity in a short time and enables the cost reduction and the shortening of an evaluation time. SOLUTION: The method for evaluating the pitting sensitivity on stainless steel includes a dipping process that generates at least two or more test pieces of the stainless steel with polished measurement surfaces, and individually dips the test pieces into liquids with different concentrations of chlorine ions, a process for the measuring film thickness that measures reflection light to incident light by a microscopic ellipsometry with a CCD camera on films formed on the surfaces of the test pieces after the dipping process, and a sensitivity evaluating process for plotting a correlation between the film thickness obtained in the process for measuring the film thickness and the concentrations of the chlorine ions on dipping the test pieces into.
