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 
varying like 
(
) in a wide temperature range from 7 K to 700 K.
