Abstract

This stationary turbine blade comprises: a stationary blade main body extending in the radial direction intersecting the flow direction of steam; a hydrophilic region which is formed on the surface of the stationary blade main body and which has a higher hydrophilicity than the other parts and has the radial dimension gradually increasing toward the downstream side in the flow direction; and a collecting portion which is provided on the downstream side of the hydrophilic region and which collects a liquid film flowing along the hydrophilic region.
