The nuclear spin lattice relaxation time T_1 of the 3d- and 4d-series impurities (V, Mn, Co, Cu, Nb, Mo, Ru, Rh, and Pd) dissolved dilutely in Fe metal has been measured as a function of external magnetic feild strength by pulsed NMR technique. The relaxation mechanisms for these impurities in high external magnetic field are discussed in terms of the hyperfine interactions with the s- and the d-band electrons. The density of states of the impurity d- electrons in the Fe metal is calculated using the Wolff and Clogston model and used for the calculation of the relaxation time. External field dependence of the relaxation time was discussed by the spin wave mechanism. The relaxation mechanism in the ferromagnetic metal proposed by Weger has been also derived by the susceptibility formalism.
