PROBLEM TO BE SOLVED: To provide a moisture separation structure effectively removing produced water drops, reducing wet loss, and improving thermal efficiency of a turbine, in a steam turbine having a wet steam flow containing water drops. SOLUTION: Steam containing moisture and humidity is taken from small holes 8, 9 arranged in the upper part of a stator blade 4 to the inside of the stator blade. An ejector 12 is arranged to a diaphragm 2 fixing a stator blade train, and steam containing moisture and humidity sucked from the inside of the stator blade is forcibly introduced to the ejector 12. Further, steam from a drain pot 11 arranged in a moving blade inlet of the preceding stage is taken to the inside of the ejector 12, and larger pressure difference is produced in the inside of the ejector, thereby, steam suction of the ejector becomes more effective.
