In the framework of the littlest Higgs Model with $T$-parity, we discuss the top partner production at future $e^{+}{e}^{-}$ collider. We calculate the cross sections of the top partner production processes and associated production processes of Higgs and top partner under current constraints. Then, we investigate the observability of the $T$-odd top partner pair production through the process $e^{+}{e}^{-}\to T_{-}{\overline{T}}_{-}\to t\overline{t}{A}_H{A}_H$ in the $t\overline{t}$ dilepton channel for two $T$-odd top partner masses $m_{T_{-}}=603\left(708\right)$ GeV at $\sqrt{s}=1.5$ TeV. We analyze the signal significance depending on the integrated luminosity and find that this signal is promising at the future high energy $e^{+}{e}^{-}$ collider.
