Since electrons can exchange energy via emitting and absorbing plasma waves,the effect of ion sound waves on electron transport is studied. The electron thermal conductivity is calculated by reducing an additional electron-electron collision term from the Balescu-Lenard collision intergal. The calculated result shows that the electron thermal conductivity becomes smaller than that by Braginskii's theory.
