  The T-odd leptons are the typical particles predicted by the littlest Higgs
model with T-parity (LHT model) and the observation of these particles might be
regarded as the direct evidence of the LHT model. In this paper, we investigate
the production of a pair of T-odd leptons associated with a gauge boson
$V$($\gamma$ or $Z$) at the international linear $e^{+}e^{-}$ collider (ILC).
The numerical results show that the possible signals of the T-odd leptons may
be detected in the future ILC experiments.
