　This paper describes experimental verification to evaluate the modeling method to simplify reinforced concrete structure, whose fine steel structure causes an increase in computation amount, in a numerical analysis of electric field generated by a railway. In the experiment, the electric field generated by electric wires near a reinforced concrete pole is measured by a field mill. The electric field distribution in this problem is evaluated also by the finite element analysis using this simplification method. In this study, the electric field analysis considering the atmospheric electric field is also discussed. As a result of comparing the experimental results and the numerical results, it was found that the analysis using this simplification method was effective when high voltage was applied to the electric wires. However, a large error of the numerical result to the experimental result observed when the electric wires were in blackout.
