An integral dispersiton relation in k-space was derived for the linear normal modes of electrostatic perturbations in an inhomogeneous plasma under the presence of a strong ambipolar electric field. This ambipolar field causes E^^^<&xrarr>×B^^^<&xrarr> drift with the velocity shear. Under a local method, kℓ>>1,where k is the wavenumber and ℓ is the scale length, the effects of ambipolar field and magnetic curvature on drift wave were investigated in a cusped configuration system. For γ_i<0,where γ_i=±ω_<Ei>^2/ω_<Ci>^2; |ω_<Ei>| is the characteristic frequency in the ambipolar potential and ω_<Ci> is the ion cyclotron frequency, the cusped magnetic curvature tends to have a stabilizing effect in addition to the ambipolar field on a drift instability. For γ_i>0,however, the curvature effect seems not to be so efficient even in such a configuration system.
