The effects of finite Larmor radius (FLR) and diamagnetic drift on the current diffusive ballooning mode is studied. Starting from the reduced magnetohydrodynamic equations which include the effects of turbulent transport, the coupling with drift motion and the FLR effect of ions, we derive a ballooning mode equation with complex transport coefficients. The eigenfrequency, saturation amplitude and transport coefficients are evaluated numerically from the marginal stability condition. We found that the FLR effect increases the electron transport coefficients and that the finite drift frequency leads to the reduction of transport coefficients or the stabilization of the mode.
