PROBLEM TO BE SOLVED: To obtain a high-performance turbine stage by reducing lowering or performance due to interference of a stationary blade and a moving blade in an axial flow turbine. SOLUTION: The stationary blade is formed with the trailing edge line of the blade projected to the loop side with respect to the radial line radially extending from the center of rotation of a rotating shaft, and the moving blade is formed with the center of gravity line of the blade projected to the loop side with respect to the radial line radially extending from the center of rotation of a rotating shaft. When the angles made between the blade trailing edge tip part and the blade trailing edge root part of the stationary blade and the above radial line areθnt,θnr, and the angles made between the center of gravity line of the section of the blade tip part and the center of gravity line of the section of the root part of the moving blade and the above radial line areθbt,θbr, 1<θnr/θnt 1<θbt/θbr.
