We reexamine theoretically the fluctuation-induced conductivity of dirty type-II superconductors in bulk above the superconducting transition (i. e., H > H/sub c/2(T) or T > T/sub c/(H)). In our calculations, we have included the contribution from dynamic fluctuations. The resulting conductivity decreases much faster than predicted by earlier theories, as the field (or the temperature) increases, which satisfactorily accounts for the experimental data obtained by Hake et al., and by Johnson et al.
