Abstract
This turbine stator vane extends in the radial direction which intersects the flow direction of steam, and includes a pressure surface facing the upstream side in the flow direction, and a suction surface facing the downstream side in the flow direction. A plurality of grooves are formed in at least the pressure surface, the grooves extending outward in the radial direction toward the downstream side. At the periphery of the grooves in the pressure surface, formed is a hydrophilic uneven region having greater hydrophilic properties than the pressure surface. The downstream-side ends of the plurality of grooves are connected to slits for capturing a liquified component of the steam.
