Here we report the impurity effect on superconducting transition temperature $T_\\mathrm{c}$ in the newly discovered Cr-based superconductor K$_2$Cr$_3$As$_3$. The resistivity measurements show that the crystals prepared using high-purity Cr metal ($\\geq$99.99\\%) have an electron mean free path much larger than the superconducting coherence length.
