Abstract
CP violation in semileptonic top-quark decay is investigated by exactl y using one charged- and three neutral-Higgs bosons obtained by solvin g the Higgs mass matrix in the two-Higgs-doublet model. The CP-violati ng up-down asymmetry of leptons from W boson decays is shown to be 1 X 10(-4)-4 X 10(-3) for the region of tan beta much less than 1, where tan beta is the ratio of vacuum expectation values for the two neutral Higgs bosons.
