Kinetic theory of high-n (n: toroidal mode number) electromagnetic ballooning mode is presented with consistent inclusion of plasma β-value, ion gyroradius, kinetic parallel conductivity, ∇B drift and magnetic shear effects. A new unstable branch of nonlocal eixenmodes in a collisionless toroidal plasma is found. The growth rate of kinetic high-n ballooning mode is of order of drift frequency.
