The study of the superconducting-gap of MgB2 with the help of high resolution angle resolved photoemission spectroscopy was presented. It was shown that the superconducting gaps with values of 5.5 and 2.2 meV open on the σ band and the π band. The σ and π-band superconducting gap values agreed well with the previous angle-integrated (AI) PES results.
