PROBLEM TO BE SOLVED: To provide a turbine blade formed of ceramic material withstanding even in a high-temperature environment. SOLUTION: The turbine blade is formed of the ceramic material and has a blade cross-sectional shape in a circumferential direction of a turbine, which is displaced and curved to at least one of an axial direction and the circumferential direction of the turbine. Provided that a flowing direction of fluid introduced into the turbine is a positive axial direction and the ventral side of the blade is a positive circumferential direction, the curvature is formed by the circumferential cross-sectional shape of the blade displaced only in a negative axial direction, only in the negative axial direction and the positive circumferential direction, the positive axial direction or only in the positive axial direction and a negative circumferential direction.
