It is shown that when the direct coupling between fermion and Higgs field approaches zero, but the Dirac mass is kept finite, then the necessary condition of the fermion-monopole bound state is not satisfied. This result means that the Rubakov effect is absent for SU(2) monopole because of the Dirac mass.</p> <br/>Acta Physica Sinica. 1985 34(11): 1488-1493.
