By making use of the many band Hamiltonian, the effect of the electron correlation on (1/T_1)_<orb> for ferromagnetic metals is investigated by solving the Green function within RPA. It is found that only the contribution from the interband transition is affected by the electron correlation. For the case of the saturated ferromagnets, it is found that the electron correlation enhances the relaxation rate by a few time, in the tight binding approximation. The numerical calculation of the enhancement factor for nickel is done making use of a simplified two band model. The results shows that the effect of the electron correlation on (1/T_1)_<orb> is important for a comparison with experiments.
