Abstract：
The thermal masses of hadrons are calculated in the effective chiral Lagrangian which reproduces the scaling anomaly of QCD. It is found that the thermal masses of constituent quark and scalar field decrease faster in one-loop approximation than in mean-field aproximation, whereas the pion at the chiral limit remains massless at all temperatures.
