We present a proof of the Korringa relation for the impurity nuclear spin-lattice relaxation of transition-metal impurities in simple metals. Two important mechanisms are considered; the relaxation due to the d-spin fluctuations and the d-orbital fluctuations. By using the 5-fold degenerate Anderson model it is shown that the Korringa relation is valid at low temperatures T≪T_k for these two mechanisms in any order of the Coulomb interaction between d-electrons. The proof can be easily extended to the Korringa relation for the Wolff model.
