We measure correlation functions of energy-momentum tensor in Nf=2+1 full QCD at finite temperature by applying the gradient flow method both to the gauge and quark fields. Our main interest is to study the conservation law of the energy-momentum tensor and to extract thermodynamical quantities from the correlation function. We adopt a fine lattice spacing a=0.07 (fm) and cover a wide range of temperature region $174\le T\le697$ MeV. The ud quark mass is rather heavy with $m_{\pi}/m_{\rho}\simeq0.63$ while the s quark mass is set to approximately its physical value.
