Abstract

The invention relates to a metallic flat gasket with at least one metallic gasket layer, which is mainly flat and shows a first and second surface, wherein a plane of the gasket runs centered between said flat areas, wherein a camber is formed within the gasket layer, which protrudes over the first surface of the gasket layer and which has a larger length than width, wherein the camber possesses a first level given by a virtual level, which runs in parallel to the plane of the gasket through the foot of the camber on the first surface of the gasket layer and a second level, given by a further virtual, which runs through the highest point of the camber and also parallel to the plane of the gasket of the gasket layer, wherein the camber possesses a slope area that ascends between the two levels. The slope area is provided with an undulating structure such that it comprises at least two waves each with a wave crest and a wave trough.
