PROBLEM TO BE SOLVED: To obtain a numerical analysis method capable of accurately reflecting the state of the scene and precisely estimating the corroded state of a conductor. SOLUTION: The numerical analysis method of a corrosive environment generated in the conductor 3 in a medium by a leaked current comprises a reference model analysis process for constructing and analyzing a reference model where current flows from a leaked current source 1 to an inflow object 2 via a medium while the conductor 3 is removed; a region potential distribution extraction process for obtaining a potential distribution at a region where the conductor 3 is present from the obtained potential distribution; and an object-to-be-analyzed analysis process for determining that the conductor 3 comprises a plurality of analysis segments and determining the analysis polarization characteristics of the segments, based on the potential distribution of the region and the material polarization characteristics of the conductor 3, performing an analysis in which only the conductor 3 is present in the field and a macro cell is formed by the segments, and obtaining the polarization potential distribution of the conductor 3 and the outflow/inflow distribution of current from the conductor to the medium.
