We have performed the soft X-ray photoemission and absorption studies of CaB6. The crystal field splitting in the Ca 3d levels is estimated as 0.65 eV from the analysis of the Ca 2p X-ray absorption spectrum. It is found that the surface Ca 2p contribution is seen at the lower binding energy side of the bulk Ca 2p peak in the core-level spectra. The Ca 2p-3d resonance photoemission shows the clear enhancement of the spectral weight in the vicinity of the Fermi level.
