We examine the radiative corrections to the mass of the lightest Higgs boson in the minimal supersymmetric extension of the standard model. We use the renormalization-group-improved effective potential 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 [lt][ital m][sub [ital t]][lt]200 GeV and for the supersymmetry-breaking scale [ital M][sub SUSY]=1 TeV ([ital M][sub SUSY]=10 TeV). Also we find that our result is stable under the change of the renormalization parameter [ital t].
