Summary: A direct solver for diffraction problems is presented. The solver is based on the fast Fourier transform (FFT) and the successive elimination of lines which we call SEL. In the previous paper, we showed the numerical algorithm by use of SEL and proved that the limit function of approximate solutions satisfied the diffraction problem in the sense of distribution. In this paper, the above numerical algorithm is improved with FFT and we show that the calculation speed is faster than the previous one.
