PROBLEM TO BE SOLVED: To reduce erosion of moving blades due to water drops and to improve efficiency of a steam turbine. SOLUTION: The steam turbine has the moving blades with spaces (6) formed inside, and a platform (2) to which the moving blades are attached. This, as the blades are formed hollow to reduce a weight of the moving blades. The weight of the moving blades can be reduced the moving blades can be lengthened, and by lengthening the moving blades a steam speed at an outlet of the steam turbine can be reduced and the performance can be improved.
