Several parameters of the minimal supergravity model are estimated by the method of the renormalization group. In this model, five arbitrary parameters $(m_0, m_{1/2}, \tan{\beta}, A_0, {sig}(\mu))$ are contained. $\tan{\beta}$ is evaluated as 7.5 by the likelihood analysis of the gauge and Yukawa coupling constants. Further, the trilinear coupling constant $A_0$ is fixed by the equation of $B_0=(A_0-1)m_0$ at the GUT scale $M_X \simeq 2\times10^{16}$(GeV) and by the Higgs potential at the Z-boson mass scale $M_Z=$91(GeV). As the results, (1) allowed $m_0-m_{1/2}$ regions, (2) the sparticle mass spectra, and (3) the lightest supersymmetric particle mass are shown in this paper.
