The Fermi surface and superconducting gap of MgB 2 have been studied by angle-resolved photoemission spectroscopy. Two Fermi surfaces composed of the r band and the p band are clearly observed without contaminated by the ''surface-derived'' band. The high-resolution photoemission spectra show that s
