  In this work, we investigate the Higgs-boson production processes
$e^{+}e^{-}\rightarrow ZH$, $e^{+}e^{-}\rightarrow \nu_{e}\bar{\nu_{e}}H$ and
$e^{+}e^{-}\rightarrow e^{+}e^{-}H$ in the littlest Higgs model with T-parity.
We present the production cross sections, the relative corrections and some
distributions of the final states. In the allowed parameter space, we find that
the relative corrections of the three production channels are negative, the
relative correction of the $ZH$ production can reach $-7.5\%$ and the relative
corrections of the $\nu_{e}\bar{\nu_{e}}H$ and $e^{+}e^{-}H$ production can
both reach $-6.5\%$ for $\sqrt{s}=500$ GeV with the scale $f=$694 GeV.
