The electronic structure of CeSb in the magnetically ordered states is examined by measuring the optical reflectivity, the magnetic linear dichroism and the magnetic circular dichroism spectra at low temperatures under magnetic fields in the infrared region. The optical conductivity spectrum, as well as the reflectivity spectrum changes significantly with the complex magnetic, phase diagram, and gives detailed information of electronic structures in the ordered states. The spectra in the ordered states cannot be explained only by the energy band folding due to the appearance of the periodic magnetic structure. By comparing with the calculated optical conductivity spectra, we found that not only the Ce4f-Sb5p mixing but also the Ce5d-Sb5p mixing mainly works in the ordered states.
