We report a first study of low energy electronic structure and Fermi surface topology for the recently discovered iron-based superconductor Ca10(Pt3As8)(Fe2As2)5 (the 10-3-8 phase, with Tc ~8K), via angle resolved photoemission spectroscopy (ARPES). Our results suggest that intermediary layers Pt3As8 couple only weakly to the FeAs layers in this new superconductor.
