Beschreibung
Zusammenfassung:	A guide vane is provided for a gas turbine and has an airfoil extending in the radial direction between an inner platform and an outer platform. The airfoil extends transversely to the direction of the hot gas flow between a leading edge and a trailing edge and has a pressure side and a suction side. A cooling slot running parallel to the trailing edge is provided on the pressure side in front of the trailing edge, a cooling medium can exit through the cooling slot from the guide vane over the entire length of the guide vane and can cool the trailing edge of the guide vane. In such a guide vane, the service life is extended by a thermal stress reducing element provided on the inner platform below the trailing edge and the cooling slot.
