PROBLEM TO BE SOLVED: To provide a turbine nozzle of a gas turbine engine which is easily manufactured and capable of suppressing flutter of the turbine nozzle as much as possible when the gas turbine engine is operated. SOLUTION: In the turbine nozzle 45A with blades stacked in the height direction, top parts on a back side of the blades 47 when viewed forward of or backward of the turbine nozzle 45A which are continuously formed in the height direction of the blades 47 are curved to the web side in a parabolic line, and curved to a maximum at the center in the height direction of the blades 47 with respect to a line connecting an intersection part of the top parts with a hub 49 of the turbine nozzle to an intersection part 51 of the top parts with a tip of the gas turbine nozzle, and the maximum curved value is within a range of 0.02-0.03 time the height of the blades.
