Abstract
A turbine stator vane comprising: a vane body; a shroud formed at an end of the vane body in a vane height direction; a fillet portion joining the vane body and the shroud; and a plurality of cooling holes in a bottom plate contacting a combustion gas flow path. The plurality of cooling holes connect to entry openings and downstream exit openings formed in the bottom plate. The entry openings and the exit openings are connected by cooling hole center lines having the same inclination with respect to an axial direction. The plurality of cooling holes constitute a set of cooling hole rows in which a linear first opening center line connecting the centers of the exit openings and a linear second opening center line connecting the centers of the entry openings are formed parallel to each other.
