PROBLEM TO BE SOLVED: To form a cooling layer to generate stable cooling air streams on surfaces of stator blades and turbine blades having cooling slots. SOLUTION: An aerofoil 60 is composed of a leading edge 74, a trailing edge 76, the forefront 81 of a first blade end 94, and the root 79 of a second blade end 95, wherein the forefront 81 and the root 79 are separate in the radial direction, and further has cooling passage 91 extended between the leading edge 74 and the trailing edge 76 and at least one cooling slot 45 having a suction end in communication with the cooling passage 91 and accommodating fluid and an exhaust end adjoining to the trailing edge 76. The airfoil is characterized in that a suction port 96 and an exhaust port 97 lie in different radial positions in the aerofoil 60 relative to the cooling slot(s) 45. COPYRIGHT: (C)2008,JPO&INPIT
