Higgs boson in the standard model (SM) is expected to play a crucial role on electroweak symmetry breaking and giving masses for the SM particles. However, the Higgs boson has not been discovered yet, and hence, the lower limit on the Higgs boson mass is set by LEP2 experiment and it is about 114 GeV. Since the minimal supersymmetric standard model (MSSM) is a two Higgs doublet model, the Higgs boson interactions with the SM particles depend on the Higgs boson mixing. Therefore the MSSM Higgs boson mass limit is different from the one for the SM in general. In this talk, we would like to discuss a possibility that the MSSM Higgs boson can be quite light (for example, lighter than Z-boson) even if we take into account the LEP2 constraints. We also discuss the discovery potential for such a light MSSM Higgs boson at Tevatron, LHC and B-factory experiments.
