In the present work, the temperature dependence of the scalar meson parameters is investigated in the framework of thermal QCD sum rules. We calculate the sigma-pole and the non-resonant two-pion continuum contributions to the spectral density. Taking into account additional operators appearing at finite temperature, the thermal QCD sum rules are derived. The temperature dependence of the shifts in the mass and leptonic decay constant of the scalar sigma(600) meson is calculated.
