We use the renormalization-group-improved efFectivepotential which includes the next-to-leading-order contributions. We find that the higher-order corrections to the lightest Higgs boson mass are non-negligible, adding 3-11 GeV (3-9 GeV) to the result in the leading logarithm approximation for the range of top quark mass 100 GeV
