1. A turbine stator blade comprising:
a pressure side extending in a radial direction intersecting a flow direction of steam and facing upstream in the flow direction,
wherein a slit extending in the radial direction and capturing a liquefied component of the steam is formed on a downstream side of the pressure side,
a hydrophilic uneven region having a liquid film capacity greater than that of the pressure side by being recessed in a depth direction intersecting the pressure side is formed in a further upstream position than the slit, and
the hydrophilic uneven region has a depth in the depth direction increasing and a flow resistance decreasing toward downstream and toward the slit.
