The Green function for s-electrons is calculated perturbationally with respect to the mixing interaction in order to investigate the Kondo effect in the Anderson model in superconductors. By taking the limit U→∞, it is shown that, at least to the lowest order, any singularity does not occur in the nonmagnetic case (E≫T), and that the singularity in the magnetic case (E<0,|E|≫T)) is of a little different form from that of the s-d exchange model. In the nonmagnetic case, the initial decrease of superconducting transition temperature is calculated perturbationally by taking the value of U finite and the result is compared with that of the Hartree-Fock approximation.
