The change of the electronic structure near the Fermi level of Yb 4As3 due to the charge ordering is examined by measuring the temperature dependence of reflectivity spectra of Yb4(As 1-xSbx)3, (x = 0,0.12,0.24) in the photon energy range of 2 meV - 1.5 eV. In the optical conductivity spectra, a peak commonly appears at 0.4 eV below the temperature that is a little higher than the charge ordering temperature. Its intensity increases as the temperature decreases. The peak intensity indicates the ratio of the charge-ordered state for the whole because it originates from the optical transition to the Yb 5d band in the charge-ordered state.
