PROBLEM TO BE SOLVED: To provide a steam turbine stationary blade capable of effectively removing a water film.SOLUTION: A steam turbine stationary blade 101 having a hollow part 113 thereinside includes: a plurality of slits 110, 111 that is provided so as to communicate a working fluid flow passage and a hollow part 113 and extend in a blade length direction, and is arranged in a cord length direction; and at least one connection part 112 that is provided correspondingly to the most downstream slit 111 among the plurality of slits 110, 111 so that a surface on a working fluid flow passage side is positioned closer to the side of the hollow part 113 than a blade surface, and connects wall surfaces on both sides in the cord length direction of the most downstream slit 111.SELECTED DRAWING: Figure 3 |
