The undergound space is widely developed because of dometic industry and protection of enviornment. The existence and exact location of tunnel is very important for stability of the enormous underground storage house or building. Various types of prospecting methods have been applied to detection of underground tunnel. In this study, electrical prospecting method is applied to detect tunnel because the development of underground space is very connected with groundwater. Sensitivity analysis is introduced for the calculation of elctrical inversion data. The governing equation is Fourier transformed into the 2-dimensional wave number space and solved by using the finite element method.
