A turbine blade which can be subjected to a hot gas flow includes a substrate, at least one interior space and a plurality of bores leading from the interior space out of the substrate. The substrate is at least partly covered by a heat-insulating-layer system at a suction side and/or a pressure side. At least one of the bores is closed by the heat-insulating-layer system and at least one further bore is open for developing film cooling.
