Abstract:
A turbine vane (3) includes: a vane body (21); a plate-like inner shroud (22) provided at a radially inner end of the vane body (21); and a plate-like outer shroud (23) provided at a radially outer end of the vane body (21). The vane body (21) includes a serpentine channel (30) which is formed so as to meander inside the vane body (21) in the radial direction and through which a cooling medium flows. The inner shroud (22) includes a cooling path (40) which has one end open at the downstream end side of the serpentine channel (30) and the other end open at a trailing edge (22D) of the inner shroud (22) and through which the serpentine channel (30) communicates with the outside of the inner shroud (22).
