N2 - A holographic model of QCD at finite temperature is proposed and thermal properties for light mesons are examined in terms of this model. We find interesting temperature dependences of masses and decay constants for several mesons, and the Nambu-Goldstone theorem for the chiral symmetry breaking and the generalized Gell-Mann-Oakes-Renner relation are assured at finite temperature. In the chiral limit, the speed of a pion in the thermal medium is found to decrease as temperature increases to the critical temperature of quark confinement-deconfinement transition.
