The thermal conductivity κ of the superconductor Ir1−xPtxTe2 (x = 0.05) single crystal with strong spin-orbital coupling was measured down to 50 mK. The residual linear term 
is negligible in zero magnetic field. In low magnetic field, shows a slow field dependence. These results demonstrate that the superconducting gap of Ir1−xPtxTe2 is nodeless, and the pairing symmetry is likely a conventional s-wave, despite the existence of strong spin-orbital coupling and a quantum critical point.
