A turbine blade/vane includes a profiled blade/vane aerofoil, which extends along a blade/vane center line. A platform is formed on an end region of the blade/vane aerofoil, extending transverse to the blade/vane center line. This is to be designed for a particularly high capability for carrying thermal and mechanical loading. In addition, the arrangement permits reliable cooling with a comparatively small coolant requirement. For this purpose, the platform includes an outer rim which is thickened in comparison with the platform floor. The side wall of the outer rim facing toward the blade/vane center line is slanted relative to the latter. A casting system suitable for manufacturing the turbine blade/vane includes a first shell element which can be positioned in a casting mold, an essentially flat configuration second shell element being displaceable, while being guided in a direction tilted by an angle of more than 10° and of less than 80°, in the first shell element.
