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.
