It is demonstrated that the light Higgs boson scenario, in which the lightest Higgs mass is less than the LEP bound, mh>114.4 GeV, is consistent with the supersymmetric seesaw model. With the assumptions of the universal right-handed neutrino mass and the hierarchical mass spectrum of the ordinary neutrinos, the bounds for the right-handed neutrino mass are investigated in terms of lepton flavor violating charged lepton decays. We also discuss the effect of the modification of renormalization group equations by the right-handed neutrinos on the b\ensuremath→s\ensuremathγ process and the relic abundance of dark matter in the light Higgs boson scenario.
