Effects of impurities on the conductance in normal-metal/d-wave superconductor junctions are discussed. By using the single-site approximation, it is shown that the impurity scattering causes the split of the zero-bias conductance peak (ZBCP). So far, the split of the ZBCP at the zero magnetic field
