The invention relates to a metallic flat gasket (1) with at least one gas ket layer (2), in which at least one through opening (3) is present, which i s surrounded by a sealing area (4), in which at least one elastically deform able element (5) surrounding the through opening (3) is arranged, and an opt ional, at least one functional area (6) with at least one elastically deform able sealing or supporting element (7), which does not separately surround a single through-opening, where outside of the at least one sealing area (4) and the optional at least one functional area (6) on at least one of the sur faces (21, 22) of at least one of the gasket layers (2) an area is surface s tructured in such a way that the gasket layer (2) in this area has a thickne ss that is larger than the original thickness of the gasket layer (2). The s urface structured area (8) covers the at least one surface (21, 22) outside of the sealing (4) and the functional area (6) at least in regions and the s urface structure is formed by alternating depressions (9) and protrusions (1 0) which run on at least one cohort of essentially parallel, straight virtua l lines extending over the total area of the structured area (8).
