The spontaneous breakdown of SO(10) symmetry of the IIB matrix model has beenstudied by using the improved mean field approximation (IMFA). In this report,the eighth-order contribution to the improved perturbative series is obtained,which involves evaluation of 20410 planar two-particle irreducible vacuumdiagrams. We consider SO(d)-preserving configurations as ansatz (d=4,7). Thedevelopment of plateau, the solution of self-consistency condition, is seen inboth ansatz. The large ratio of the space-time extent of d-dimensional partagainst the remaining (10-d)-dimensional part is obtained for SO(4) ansatzevaluated at the representative points of the plateau. It would be interpretedas the emergence of four-dimensional space-time in the IIB matrix model.Comment: 13 page
