PROBLEM TO BE SOLVED: To obtain a numerical analyzing method capable of accurately reflecting the state of the spot to precisely estimate the corrosion state of a conductor. SOLUTION: In the numerical analyzing method of a corrosive or corrosion-proof environment for regarding the corrosion-proof state of an electric corrosion-proof place, where the current flowing out of a current outflow source flows in an inspection target, as a continuous body, which is composed of a plurality of the analyzing segments electrically connected to the inspection target to analyze the same, as a setting method of the material polarization characteristics of the analyzing segments on the surface of the inspection target, a weight coefficient is used with respect to the respective analyzing segments on the basis of the polarization characteristics of the actually measured material measured at each of the measuring positions on the surface of the inspection target to interpolate the potential value to a constant current value from a part of or all of the polarization characteristics of the actually measured material and the led-out polarization characteristics of the interpolated material are set as the polarization characteristics of the material in the respective analyzing segments.
