A gas turbine provided with: a compressor (11) wherein a compressor chamber (21) forms a ring-shaped air passageway (49); a rotor (32) that is rotatably supported in the center of the compressor chamber (21); a plurality of rotor blade bodies (46) that are spaced at a predetermined axial direction interval, are affixed to the outer periphery of the rotor (32), and are arranged in the air passageway (49); a plurality of stator blade bodies (45) that are affixed to the compressor chamber (21) between the rotor blade bodies (46) and that are arranged in the air passageway (49); a cooling-air flow path (61) that is provided so as to face the outside of the plurality of rotor blade bodies (46) that are in the compressor chamber (21); a first cooling-air supply route (71) that provides a portion of compressed air (A) to the cooling-air flow path (61); a cooler (72) that cools the compressed air of the first cooling-air supply route (71); and a second cooling-air supply route (73) that supplies cooled air in the cooling-air flow path (61) to a cooling part of a turbine (13). |
