It is studied that `no-scale' model makes hierarchy between scalar top mass and Z boson mass naturally. The supersymmetry breaking parameters are constrained by flavor changing neutral currents in minimal supersymmetric standard model. One of the solution of the problem is that gaugino mass is the only source of the supersymmetry breaking parameters at Planck scale. However, in such scenario, we need a cancellation between Higgs mass parameters in minimization condition of the Higgs potential. We insist that there is no such cancellation in no-scale model, and that the no-scale model gives us the prediction of scalar top mass and lightest Higgs mass. The lightest Higgs mass is predicted as $m_H = 110 \pm 5 $ GeV.
