Abstract
A turbine stator blade () includes a pressure side (P) extending in a radial direction intersecting a flow direction of steam, and facing upstream in the flow direction. A slit () extending in the radial direction and capturing a liquefied component of the steam is formed on a downstream side of the pressure side (P). A hydrophilic uneven region () having a liquid film capacity greater than that of the pressure side (P) by being recessed in a depth direction intersecting the pressure side (P) is formed in a further upstream position than the slit (). The hydrophilic uneven region () has a depth in the depth direction increasing and a flow resistance decreasing toward downstream and toward the slit ().
