Electroweak symmetry breaking is explored in a two Higgs doublet model based on a six dimensional SU(4) gauge-Higgs unification compactified on an orbifold T2/Z2. The remarkable property of this model is a prediction of realistic weak mixing angle sin2 θW = 1/4 at the compactification scale. We calculate one-loop effective potential of the Standard Model Higgs boson from the contributions of the gauge boson and the fermion in a four-rank totally symmetric tensor where top quark is included. We find that the electroweak symmetry breaking certainly takes place.
