An outlet seal connects a combustor that combusts a fuel to generate combustion gas and a shroud for a stator. The outlet seal has a gas path surface, a first connection section, and a second connection section. The shape of the gas path surface in a cross section perpendicular to an axis is an arc centered on the axis. The first connection section is formed at a first side in an axial direction and is connected to the combustor. The second connection section is formed at a second side in the axial direction and is connected to the shroud. The gas path surface has an inclined surface that is inclined with respect to the axis in a cross section including the axis, such that the flow-path area of a combustion-gas flow path is reduced toward the second side.

A plurality of cooling passages extending in an axial direction are formed in a transition piece so as to be aligned in a circumferential direction and the axial direction. One or more downstream side passages are formed in a downstream side region (Rd) within one circumferential region. One or more upstream side passages are formed in an upstream side region Ru within the circumferential region. The total cross-sectional area per unit circumferential length of the one or more downstream side passages is larger than the total cross-sectional area per unit circumferential length of the one or more upstream side passages.

A first-stage stator vane for a gas turbine includes: a first portion partially defining an airfoil which includes a pressure surface, a suction surface, and a trailing edge; and a second portion positioned at a leading-edge side of the airfoil with respect to the first portion, the second portion having a recess portion or a protruding portion. The recess portion or the protruding portion has a pair of side wall surfaces, and an angle formed between the pair of side wall surfaces is less than 90 angular degrees.
