To investigate the coherent structure in a turbulent plane jet. it is important to estimate the convective velocity of the coherent structure. In this study, the simultaneous measurement at 2 points by the X-type hot wire probe has been performed, and the new method was suggested to estimate the convective velocity more accurately by using the power spectrum and the spatial correlation of the lateral velocity fluctuation v. It is found that the convective velocity for the turbulent plane jet of this study is 0.676 times of the mean velocity of the jet centerline.
