Disclosed is a highly efficient, less expensive turbine nozzle blade that reduces the number of blades in an axial-flow turbine, while at the same time, reducing secondary-flow loss. In the turbine nozzle blade, when a differential pressure between a pressure side and a suction side of each blade, at one same axial chord position of the blade, is defined as a load of the blade, and a ratio between axial chord length "Cx" of the blade and an axial distance "xp" from a leading edge 8 of the blade at a maximum load position 32 which maximizes the blade load is defined as a maximum load relative position, the axial chord length "Cx" of the blade is greater at a hub and tip thereof than at an intermediate vertical portion thereof, and simultaneously a maximum load relative position at the hub and tip of the blade is set to be nearer to a trailing edge thereof than a maximum load relative position of the intermediate vertical portion of the blade.
