A vapor-cooling-type gas turbine comprising a blade ring (1) on which a plurality of front-stage stator blades (2) and rear-stage stator blades (3) are arranged in a ring shape respectively. Cooling passages (16,17) are formed in the front-stage stator blades (2) and rear-stage stator blades (3), the cooling passages (16,17) being adapted to be injected with cooling vapor to cool the front-stage stator blades (2) and the rear-stage stator blades (3). Each of the cooling passages (16) of the front-stage stator blades (2) and each of the cooling passages (17) of the rear-stage stator blades (3) are allowed to communicate with each other through a communication passage (11,18,19,20,12,13) in a one-to-one correspondence. The communication passage (11,18,19,20,12,13) and the cooling passages (16,17) formed in the front-stage stator blades (2) and the rear-stage stator blades (3) are connected to each other through a flexible connecting pipe (21,22,23,24).
