The corrections to the mean-field approximation are evaluated in a 1/d expansion. The calculations are carried out for a mixed action of SU(2) gauge theory. The results obtained with a 1/d corrections are in good agreement with the Monte Carlo data obtained previously. We also point out that the one-loop correction around a non-trivial saddle point contains a term of order d, which remains to be finite at an infinite d. This is observed for a general form of action except for the Wilson type of action. Then we must calculate to one-loop corrections to obtain an exact feature of the theory written by a general form of actions at an infinite space-time dimension.
