In a turbine vane (41) and a gas turbine, an outer shroud (45) is fixed to one end of a vane body (44) formed in a hollow shape, an inner shroud (46) is fixed to the other end thereof, and a partition plate (55) is fixed to the inner portions of the vane body (44), the outer shroud (45), and the inner shroud (46), so that a cavity (61) is formed so as to be continuous between the partition plate (55) and the group of the vane body (44), the outer shroud (45), and the inner shroud (46). Then, the vane body (44), the outer shroud (45), and the inner shroud (46) are provided with a plurality of cooling holes (52), and the partition plate (55) is provided with a plurality of penetration holes (65, 74, 84, 94). Accordingly, since the vane structure or the end wall structure is evenly cooled, a deformation or damage may be suppressed. |
