N2 - We have studied the electronic structure of the stripe-type charge-orbital ordered phase of IrTe2 by means of angle-resolved photoemission spectroscopy. An electron pocket at the Brillouin zone boundary and hole Fermi surfaces around its center are clearly observed in agreement with the band structure calculation for the stripe-type charge-orbital ordered phase. The present study indicates that the hole and electron Fermi surfaces can survive due to the strong Te 5p spin-orbit coupling even under the charge-orbital order. The participant of the Te 5p orbitals to the conduction band provides an interesting interplay between the charge-orbital order and the spin-orbit interaction in IrTe2.
