The Higgs boson production processes $e^{+}e^{-}\rightarrow ZH$, $e^{+}e^{-}\rightarrow \bar{\nu_{e}}\nu_{e}H $, and $e^{+}e^{-}\rightarrow t\bar{t}H $ are very important for studying Higgs boson properties and further testing new physics beyond the standard model (SM) in the high-energy linear e+e- collider (ILC). We estimate the contributions of the littlest Higgs model with T-parity (LHT model) to these processes and find that the LHT model can generate significant corrections to the production cross-sections of these processes. We expect that the possible signals of the LHT model can be detected via these processes in the future ILC experiments.
