In the gauge-Higgs unification scenario the Higgs field is unified with gauge fields in higher dimensional gauge theory. The 4D Higgs field H(x) corresponds to 4D fluctuations of the Aharonov-Bohm phase (Wilson line phase) θH in the extra-dimension. An SO(5)× U(1) gauge-Higgs unification model in the Randall-Sundrum warped spacetime with top and bottom quarks is presented. Gauge couplings of the top quark multiplet induce electroweak symmetry breaking by the Hosotani mechanism. The effective potential V_\eff (θH) is found to be minimized at θH = \onehalf π and the Higgs mass is predicted around 50 GeV. The ZZH and WWH couplings vanish at θH = \onehalf π so that the LEP2 bound for the Higgs mass is evaded. The result is summarized in the effective interactions for θH(x) = θH + H(x)/fH.
