Query: Charged Higgs mass bound from the $b\rightarrow s\gamma$ process in the
  minimal supergravity model   We study the constraint on the mass of the charged Higgs boson in the minimal
supergravity model based on the recent measurement of the inclusive
$b\rightarrow s\gamma$ decay. It is shown that the lower bound for the charged
Higgs mass crucially depends on the sign of the higgsino mass parameter
($\mu$). For $\mu<0$, the bound exceeds 400 GeV when the ratio of two Higgs
vacuum expectation values ($\tan\beta$) is larger than 10. No strong bound is
obtained for $\mu>0$ due to cancellations between charged Higgs and
supersymmetric particle contributions. For $3\lsim\tan\beta\lsim5$, a charged
Higgs lighter than 180 GeV is excluded by this process irrespective of the sign
of $\mu$.
