The concept of Berry's phase factor in adiabatic process is generalized to degenerate systems, the relation between the quantum Hall effect and Berry's phase factor is studied. It is shown that the quantum Hall conductance σH is really a special Berry's phase factor, and thus has the same geometrical properties.
