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