PROBLEM TO BE SOLVED: To provide a monitoring system capable of more accurately analyzing the corrosion/corrosionproof problem of a metal in consideration of the change of a polarization curve with the elapse of time. SOLUTION: The potential and current density distribution in the region becoming an analyzing target surrounded by the surface including an anode surface and a cathode surface is calculated from the polarization curveψen of the initial data of the anode surface and the cathode surface by numerical analysis and the monitoring of the electrochemical state in the region is performed. After the elapse of a definite time, the potential or current density of an actual surface is measured at a plurality of the measuring points in the actual region becoming an analyzing target and the polarization curveψen corrected from the initial data is calculated on the basis of the measured potential or current density by the inverse analysis of the numerical analysis while the potential and current density distribution in the region is again calculated from the corrected polarization curveψen by numerical analysis of the monitoring of the electrochemical state in the region is performed on the basis of the corrected polarization curveψen.
