The energy band structure of the hexagonal Fe2Si bulk was along with the high symmetrical point orientation in the Brillouin zone.Fig.2 is the energy band structure of the hexagonal Fe2Si bulk，Fig.2（a）is the band structure of spin-up electronic，it exhibits a metallic characteristic structure.Fig.2（b）shows the band structure of spin-down.Table 2 is the energy of the top of valence band（Ev）and the bottom of conduction band（Ec）in the First Bril-louin-zone.Combining with Fig.2（b）and Table 2，the maximum of valence band is0.164 eV at point of S，and the minimum of conduction band is 0.682 eV at BZ point of L，which form the S-L indirect gap semiconductor with the band gap of 0.518eV in the vicinity of Fermi surface，under spin-down.
