By use of Kondo-Heisenberg model, effect of spin correlation to electron eneggy spectrum is investigated near the metal-insulator transition. Antiferromagnetic correlation strongly affects band dispersion. The difference of energy spectrum between the conventional Kondo-Heisenberg model and the one
