 note = {A structure of an edge radial electric field E_r Inferred from poloidal rotation velocity is compared with that of particle/thermal transport barrier for H-mode plasmas in JFT-2M. Both of E_r and its gradient  ( partial E _r/partial r) in the thermal transport barrier are found to become more negative at the L/H transition. The shear of radial electric field and poloidal rotation velocity in H-mode is localized within an ion poloidal gyro radius near the separatrix, in the region of ion collisionality nu_{star i} approx l0-40.},
