Abstract
A steam turbine stator vane (1) has a trailing edge curved line (9,10) on which an inflection point is provided when the stator vane (1) is viewed from a downstream side of flow of a working fluid in an axial direction of a steam turbine. The stator vane (1) is formed so that a projecting amount of the curved line (9,10) in a rotational direction of the moving blade (2) of the steam turbine continuously increases from a root portion of the stator vane (1) to a tip portion of the stator vane (1). The tip portion of the stator vane (1) is inclined toward the outer circumferential side of the steam turbine with respect to the flow direction (20) of the working fluid from the upstream side to downstream side of the flow of the working fluid. The root portion is inclined toward the inner circumferential side of the steam turbine with respect to the flow direction of the working fluid from the upstream side to downstream side of the flow of the working fluid.
