In order to investigate the turbulent boundary layer structure under a strong adverse pressure gradient accompanied with the separation, the measurements of the boundary layer characteristics are made. Especially measurements of the spanwise distribution of the mean velocity, turbulent velocities and wall shear stsess are made to examine how the boundary layer vary in the spanwise direction due to the adverse pressure gradient. Bradshaw's prediction method are examined in the present flow field which is subjected to strong three dimensional effect. Moreover, the various simple methods of separation criteria are checked. Analyses of the effect of the adverse pressure gradient on the wall law are performed using τ=τ_w+αy.
