Abstract
The gas turbine blade includes a cooling channel formed therein, and a partition disposed on its tip side for isolating the cooling channel from the outside. The partition is integrally formed with a blade portion in a position on its inner side in the radial direction with respect to the tip of the gas turbine blade. Reinforcements are provided on the outer side of the partition in the radial direction and on the inner side of the tip end wall extended from the blade portion to connect the partition with the tip end wall. Outer surface cooling holes are formed to extend from the cooling channel into communication with an outer surface of the tip end wall, and inner surface cooling holes are formed to extend from the cooling channel into an inner surface of the tip end wall through the partition.
