We present measurements of thermoelectrical properties of polygrain icosahedral quasicrystal Al72Pd19.5Mn8.5 in the temperature range 10-300 K. Electrical resistivity has a relatively low room temperature value, rR.T.=1.2 mWcm, by lowering the temperature shows increase with a maximum value at 120 K. Thermoelectric power is positive in all temperature range with quite high room temperature value SR.T.=70 mV/K. Thermal conductivity shows an maximum at 30 K, and a broad minimum around 125 K. It room temperature value is KR.T. =3.4W/mK. The appearance of the maximum in thermal conductivity at 30 K comes mainly from the structural scattering, while rising above 120 K from the contribution of localized phonon state
