A radial flow turbine rotor comprises a trunconical shaft and a plurality of blades provided on the periphery of the shaft and inclined to the axis of the shaft. The shaft and the blades are integrally formed of ceramics. The profile of the cross section of each blade, taken along a line perpendicular to the axis of the shaft, is straight between the tip and base of the blade. The tip of each blade is 1.2 to 2.0 mm thick, and each blade grows thicker from the tip toward the base.
