PROBLEM TO BE SOLVED: To provide a gas turbine blade which maintains the persistence of a membrane-like exhaust flow extending toward the side downstream refrigerant long to further increase its diffusing ability. SOLUTION: In this gas turbine blade, an exhaust nozzle 26 is formed into a horseshoes shape provided with an oxbow face wherein a membrane exhaust flow 32 is made by increasing the momentum of the refrigerant CA at the central portion and a membrane exhaust flow 30 is made by reducing the momentum of the refrigerant CA in the outside portion.
