In the parameter space allowed by the electroweak precision measurement data, we consider the contributions of the new particles predicted by the littlest Higgs model to the Higgs boson associated production with top quark pair in the future high energy linear e+ e- collider (ILC). We find that the contributions mainly come from the new gauge bosons ZH and BH. For reasonable values of the free parameters, the absolute value of the relative correction parameter δσ/σSM can be significanly large, which might be observed in the future ILC experiment with √S = 800 GeV.
