To easily manufacture a stationary blade, and to suppress its manufacturing cost.SOLUTION: A stationary blade has a blade body extending in a radial direction, and a shroud arranged at one side end of the blade body in the radial direction. The shroud has a first peripheral-direction end face oriented to a first side in a peripheral direction, a second peripheral direction-direction end face oriented to a second side in the peripheral direction, an anti-gas path face oriented to the first side in the radial direction, and a gas path face oriented to the second side in the radial direction. The anti-gas path face has a plurality of planes which are aligned in the peripheral direction while continuing over a position of the first peripheral-direction end face in the peripheral direction toward a position of the second peripheral-direction end face.SELECTED DRAWING: Figure 7 【課題】静翼の製造を容易にして、その製造コストを抑える。【解決手段】静翼は、径方向に延びる翼体と、翼体の径方向第一側の端に設けられているシュラウドと、を有する。シュラウドは、周方向第一側を向く第一周方向端面と、周方向第二側を向く第二周方向端面と、径方向第一側を向く反ガスパス面と、径方向第二側を向くガスパス面と、を有する。反ガスパス面は、周方向における第一周方向端面の位置から第二周方向端面の位置にわたって連続して、周方向に並ぶ複数の平面を有して構成される。【選択図】図７
