Spatial profiles of the plasma flow, electron temperature (T e ) and ion temperature (T i ) in the stochastic magnetic boundary layer of Large Helical Device (LHD) has been studied by simultaneous measurements using a movable multiple functions probe, which consists of Mach probes and an ion sensitive probe. The tendency of the measured spatial profiles of T e and T i is similar to the three-dimensional simulation. The results of ion saturation current (I sat ) measurement of the upstream and downstream probes indicate that the plasma flow direction is reversed in the stochastic magnetic boundary layer. I sat observations obtained deep inside of the boundary layer contradict the simulation result, even though the existence of flow reversal in the LHD stochastic magnetic boundary layer was qualitatively confirmed.
