A gas turbine equipped with a sealing device that can enhance seal performance even in a high-temperature portion on an upstream side of a turbine is provided. The gas turbine includes a rotor blade 2a having a shank 7a mounted on a disk wheel 4a and a rotor blade profile portion 22a; a stator blade 1a including a stator blade profile portion 12a and an inner circumferential end wall 14a provided on the inner circumferential side of the stator blade profile portion; and a seal fin 8a provided on the shank 7a of the rotor blade so as to face an inside-diameter surface of the inner circumferential end wall 14a of the stator blade. An abradable coating 28a is applied to such a portion of the inside-diameter surface of the inner circumferential end wall 14a of the stator blade that faces the seal fin 8a. |
