The nature of nonlinear evolution of ballooning mode for not so large value of the aspect ratio, R/a=2∿3,the parameter dependence on the critical β, and the stable high-β equilibrium configuration were investigated by a three dimensional MHD simulation based on a rectangular torus model. Consequently, a stable equilibrium is found with up 5% average β value by adjusting the vertical magnetic field and the diamagnetic effect. It turns out that ballooning modes form large convective cells concentrated in regions of unfavorable magnetic field line curvature. The difference between the m=1 internal kink mode and the ballooning mode is also discussed.
