Abstract
The eigenvalue equation for the current diffusive ballooning mode in tokamaks is derived taking the geometrical effects, i.e., triangularity and ellipticity into account. The stability boundary is obtained in the strong ballooning limit. It is found that the ellipticity plays an important role on the stability of the current diffusive ballooning mode. On the other hand, the effect of the stabilization by the triangularity appears indirectly through the magnetic well term. The geometrical effect on the transport coefficient is also discussed.
