A gas turbine vane has a vane airfoil defining a cavity extending along the longitudinal direction of the vane airfoil. A guide cylinder is disposed in the cavity to guide coolant fluid supplied from an external source thereof. A plurality of flowing holes are concentrated substantially centrally with respect to the vane airfoil in the longitudinal direction.
