In this report, following the previous report, the authors have presented the heat transfer from a vertical flat plate (70×40×1cm^3) by natural convection in the case where the transition from laminar to turbulent flow occured. And they clarified the effects of the disturbance by the turbulence plate (which was set near the front edge of the flat plate) on heat transfer. Arranging the data of the experiments, the authors reached the following conclusions : (1) The relation between non-dimensional numbers, N_<ux> and G_r, in the laminar flow region becomes as follows : [numerical formula] (2) The transition to turbulent flow begins to occur from G_r=6×10^8 (3) By using the turbulence plate, transitional point moves forwards, and the relation between N_<ux> and G_r, becomes as follows : [numerical formula]
