We have performed angle resolved photoemission experiments on heavy-fermion compounds CeRhIn and CeIrIn. The obtained spectra are compared with the results of the full-potential linear-augmented-plane-wave (FLAPW) band-structure calculations, treating the Ce 4 electrons as being itinerant. The spectral contributions from the ligand Rh, Ir or In states were well reproduced by the calculations, although the features originated from Ce 4 states near $E_{rm F}$ were not clearly observed.
