A turbine blade/vane, having a blade/vane aerofoil which extends along a blade/vane axis and through which cooling medium flows, mainly in the longitudinal direction of the turbine blade/vane, is configured comparatively simply for reliable and effective closed cooling. In particular, it is configured with the use of cooling air as the cooling medium. An incident flow duct and an efflux duct for cooling medium are routed within the blade/vane aerofoil, essentially over its complete length. The incident flow duct and the efflux duct are connected together on the cooling medium side in such a way that cooling medium passing from the incident flow duct into the efflux duct is conducted in a transverse direction along a wall inner surface, which has to be cooled, of the blade/vane aerofoil.
