Abstract
A flat seal having at least one single-piece sheet-metal seal layer is provided, which has at least one first layer region provided with at least one medium through opening and, outside the first layer region, at least one second layer region and, with the flat seal installation-ready, has a pre-determined outer contour, wherein the flat seal for the medium through opening has a medium-sealing device. In order to reduce the material requirement for manufacturing the seal layer, the seal layer is configured so that at least one sub-region of the second layer lying outside the medium-sealing device region of the seal layer is formed by a region of the sheet-metal layer that is stretched in the layer plane to achieve the pre-determined outer contour.
