The cooling hole 30 includes a straight-tube part 33 and a diffuser part 34. The diffuser part 34 includes a flat surface 37, a curved surface 38 curved rearward and forming, together with the flat surface 37, a semicircular or semi-elliptical channel cross section larger than that of the straight-tube part 33, a first section 40 in which an area of the channel cross section increases as it approaches the outlet 32 of the cooling hole 30, and a second section 41 in which the area of the channel cross section increases as it approaches the outlet 32 of the cooling hole 30 at an increase rate smaller than that of the first section 40 or is constant, extending from the first section 40 toward the outlet 32 of the cooling hole 30. The diffuser part 34 has a width equal to or twice greater than the depth of the diffuser part 34.",
