We study the flavor structure in the three site Higgsless model. In thismodel, the gauge bosons and fermions have heavy partners, coming from theKaluza-Klein excitation in the dimensional deconstruction picture. The yukawacouplings are introduced in a way to minimize the flavor chaning neutralcurrent in the light sector at the tree level. Due to the flavor mixing betweenthe light and the heavy partner fields, new effects on FCNC's appear atone-loop level. As an example of such FCNC processes, we calculate thecontribution to the b -> s gamma amplitude in the three site Higgsless model.Interestingly, heavy particles which exist in the three site Higgsless model donot completely decouple in the heavy-mass limit. One-loop level b -> s gammaamplitude is calculated by considering all possible combinations of particlesin the loop, then it is compared to the experiment. The result shows that thecentral value of the B -> X_s gamma branching ratio in the three site Higgslessmodel takes closer value to its experimental central value as one takes thelarger value of a free parameter, \varepsilon_{tR}, within a range allowed bythe precision electroweak measurement.
