Abstract
A turbine stator vane includes: a stator vane body extending in a radial direction intersecting a flow direction of steam; a recovery portion that is defined on a surface of the stator vane body, and configured to recover a liquid film flowing along the surface of the stator vane body; and a center region, which is defined on the surface of the stator vane body and includes grooves extending from an upstream side toward the recovery portion in the flow direction. Intervals between adjacent grooves decrease from the upstream side toward the recovery portion.
