  We study the deviation of Higgs production through the gluon fusion process
and the decay of Higgs boson to the bottom quark and the tau lepton in
gauge-Higgs unification from the Standard Model prediction. We find that the
signal strength of $gg \to H \to b\bar{b}, \tau\bar{\tau}$ is necessarily
suppressed comparing to the SM predictions due to the dominant suppression of
the Higgs production via gluon fusion.
