Critical magnetic field and specific heat at low temperatures and near the transition temperature T_c are calculated for superconductors containing impurities with localized electrons. Near zero temperature the thermodynamical quantities are largely affected by the Coulomb correlation between localized electrons. On the other hand, the Coulomb correlation does not play an essential role near T_c. The BCS relations for various quantities remain valid if we take into account the change of state density due to the presence of the s-d admixture. The effect of anisotropy is also briefly sketched and it is shown that the BCS relations do not remain valid if the anisotropy is taken into account. Lastly, we discuss the penetration depth.
