A theory of the longitudinal electron spin susceptibility chi/sub s/ for an antiferromagnetic superconductor (AFS) has been given. For the AFS, we have assumed a homogeneous superconducting order parameter and a one-dimensional electron band that satisfies the nesting condition epsilon-c/sub k/ = -epsilon-c/sub k+Q/, where Q is the wave vector characterizing the antiferromagnetic (AF) order. First we have studied the dependence of chi/sub s/ on the scattering rates for the scattering of conduction electrons from the nonmagnetic, spin-orbit, and magnetic impurities by regarding H/sub Q/ as a parameter and neglecting the spin-fluctuation effects (H/sub Q/ is the AF field). The effect of impurities is found to be significant. Then we have investigated the temperature dependence of chi/sub s/ by taking T/sub N/
