Abstract
A CMC turbine stator blade 1 includes a blade 2 of a ceramic matrix composite material formed or a metallic material, and a band 5 formed of a ceramic matrix composite material and supporting the blade 2. The blade 2 includes a first fitting portion 3 to which the band 5 is fitted outside. The band 5 includes a second fitting portion 7 to which the first fitting portion 3 is fitted inside. A flexible wire 8 is disposed between the fitting portions 3, 7 to fix the blade 2 and the band 5. A first groove 3a in the outer peripheral surface of the first fitting portion 3 extends in the front-to-rear direction of the blade 2. A second groove 7a in the inner peripheral surface of the second fitting portion 7a extends along the first groove 3a. The wire 8 is disposed between the grooves 3a,7a.
