The energy density and the pressure of SU(3) gauge theory at finite temperature are studied by direct lattice measurements of the renormalized energy-momentum tensor obtained by the gradient flow. Numerical analyses are carried out withcorresponding to the lattice spacing. The spatial (temporal) sizes are chosen to be, 96, 128 (, 16, 20, 22, 24) with the aspect ratio,. Double extrapolation,(the continuum limit) followed by(the zero flow-time limit), is taken using the numerical data. Above the critical temperature, the thermodynamic quantities are obtained with a few percent precision including statistical and systematic errors. The results are in good agreement with previous high-precision data obtained by using the integral method.
