PROBLEM TO BE SOLVED: To provide a turbine blade part, having an improved trailing edge cooling which does not require heat insulating coating. SOLUTION: A blade part 40 to be used for gas turbine engine is provided with a positive pressure side 42 and a negative pressure side 44 to be connected to each other in a trailing edge wall 60 forming a trailing edge 48. The blade part 40 includes at least one cooling hole 68, which extends through the trailing edge wall 60 and feeds the cooling fluid from the positive pressure side 42 to the negative pressure side 44 of the blade part 40. |
