We study the Higgs sector of the minimal supersymmetric standard model extended with vector-like quarks, at the one-loop level. The radiative corrections to the tree-level masses of the scalar Higgs bosons are calculated by including the contributions from the loops of top quark, vector-like quarks, and their scalar superpartners, for a reasonable parameter region. We find that the mass of the lightest scalar Higgs boson at the one-loop level should be larger than 85 GeV, if we take into account the negative experimental result for the Higgs search at LEP2. As the radiative corrections are calculated in some detail, we also find that the mass of the lightest scalar Higgs boson at the one-loop level is bounded from above at 280 GeV, This upper bound is increased from a previous result. It may provide a wider possibility for the future collider experiments to discover the lightest scalar Higgs boson of this model.
