• We study the impurity effect in the time reversal symmetry (T) breaking superconductor based on the Bogoliubov-de Gennes (BdG) equations. In T-violating superconductors, spontaneous currents are induced around the impurity. The current patterns around the impurity reflect the structures of the Cooper pairs. We investigate impurity problem numerically for two kinds of T violating superconductors (p_x ± ip_y and d + is) and investigate the currents around the impurity. We also study the effects of the magnetic impurity in p-wave (p_x ± ip_y) superconductor, especially in view of the zero-energy crossing of energy levels related to the phase transition of the ground state.
