Abstract

The invention relates to a metallic flat gasket comprising two or more metallic gasket layers (2, 3, 3', 3''), of which a shortened gasket layer (2) has a smaller surface area than the at least one other gasket layer. At least one through-opening (4) extending through the gasket layers is surrounded by a self-contained bead (5) which is introduced into one of the relatively extensive gasket layers (3), the shortened gasket layer (2) leaving free an outer edge region (6), which does not comprise the bead (5), of the relatively extensive gasket layer. At least one structuring (7) is present in one of the gasket layers, in a region of the gasket in which the shortened gasket layer (2) is present or directly laterally adjoining this region adjacent to the position of the bead (5), said structuring protruding beyond at least one surface of the gasket layer and consisting of a large number of alternating elevations (31) and depressions (32) which are introduced into the gasket layer, the structuring (7) being present at least in certain portions in the circumferential direction around the through-opening (4).
