The muon longitudinal polarization PL in KL-->mumu¯ decay is investigated in the standard model. The induced s¯dH vertex responsible for PL turns out to be unexpectedly ``large.'' The measurement of PL above ~10-3 will, therefore, be a signal of the existence of a rather light Higgs boson (MH<~10 GeV). It is also shown that the mechanism of gauge-dependence cancellation between Higgs-boson-exchange and box diagrams works even in the standard model.
