By using thermo field dynamics (TFD) and Ginzburg‐Landau theory, the fluctuation effects on conductivity are studied for layered superconductors above critical temperature. It is argued that the broadness of the resistivity is due to the decoupling of electron tunneling among layers. The results are compared with experiments.
