The stability of a drift wave in an inhomogeneous plasma with magnetic shear is studied. The characteristic trapped-electron cone for the tokamak configuration is taken into account. This cone substantially changes the interaction of the electrons and the drift wave from that in the model of a plane plasma slab. In the tokamak case, a drift wave is stable; i.e., the universal instability does not occur.
