We present a direct search result for a charged Higgs boson in lepton+jets tt-bar events using 2.2 fb{sup -1} data collected by CDF II detector. The charged Higgs boson is predicted to decay into cs-bar in low tan {beta} in the MSSM if its mass is smaller than the top quark. Looking for a second peak from the di-jet invariant mass in decays of top quark, there is observed no evidence of anomalous boson. We place the upper limits on the br(t{yields}H{sup +}b) = 0.1{approx}0.3 with 95% C.L. depending on the charged Higgs mass.
