The electron distribution function in a plasma with the steep temperature gradientis obtained from the Fokker-Planck equation by the Green's function method, ex-tending the previous differential formula [J. Phys. Soc. Jpn. 52 (1983) 3389]. Theformula describes the nonlocal effects on the thermal transport over the range of)./L<0.1 (2.: electron mean free path, L: temperature scale length). The formula in-cludes the self-consistent electrostatic potential and exactly recovers the Spitzer-Hirmthermal conductivity in the long scale length limit, )./L-+0. As an example, the heatwave propagation is numerically analyzed by employing the integral formula and thenonlocal properties of the heat flux, which is obtained in the Fokker-Planck simula-tion, are well reproduced.
