Temperature Dependence of the electronic structure of Yb,jAs3 wets investigated by the observation of the reflectivity spectra in the energy range from 2 rneV to 50 eV at several temperaturesfrom 39 to 320 K. In the photon energy range below 10 men, the ternperature dependence of thespectrum can be qualitatively explained by two-band model previously proposed. An absorptionband with strong temperature dependence was observed al, 0,4 eV. The origin is considered to bethe mixing state between unoccupied Yb"-4/ and 5d. The state is considered to be importantto understand the anomalous temperatture dependence of the physical properties. In the energyrange above l eV, the spectruna does not change with tlxe temperature. The structtmre of theoccupied and unoccupied states near the Fermi level is clarified.
