We present indications for a metal-insulator transition in the icosahedral AlPdRe phase of high structural quality. We follow the conductivity through the transition and its dependence on temperature and magnetic field in a series of i-AlPdRe samples. Features typical for systems on both sides of the metal-insulator transition are found. Moreover, the variation of conductivity with temperature is very unusual with σ(T) varying like Tα (1 ⩽ α ⩽ 1.5) in a wide temperature range from 7 K to 700 K.
