PROBLEM TO BE SOLVED: To provide a sealing device for a gas turbine capable of maintaining good sealing performance with flexibly coping with a case that difference of thermal expansion quantity between structure members is produced. SOLUTION: This sealing device 33 for the gas turbine is stretched over seal grooves 32b-1, 32b-2 provided on opposing end surfaces of structure members 21a-1, 21a-2 adjoining each other, and seals a gap between the structure members 21a-1, 21a-2. The device is provided with a plurality of thin plate shape seal plate 40a having larger dimension in a groove depth direction of the seal grooves 32b-1, 32b-2 than gap dimension between the structure members 21a-1, 21a-2, and a plurality of spacers 40b having smaller dimension in groove depth direction of the seal groove 32b-1, 32b-2 than the seal plate 40a, and is provided with a seal main body 34 laminating seal plates 40a and spacers 40b with aligning end parts 41 in a groove width direction of the seal grooves 32b-1, 32b-2 and fixing the same each other in one seal groove 32b-2.
