The invention relates to a metallic flat gasket (1) with at least one gasket layer (2), in which at least one through opening (3) is present, which is surrounded by a sealing area (4), in which at least one elastically deformable element (5) surrounding the through opening (3) is arranged, and an optional, at least one functional area (6) with at least one elastically deformable 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 surfaces (21, 22) of at least one of the gasket layers (2) an area is surface structured in such a way that the gasket layer (2) in this area has a thickness that is larger than the original thickness of the gasket layer (2). The surface 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 surface structure is formed by alternating depressions (9) and protrusions (10) which run on at least one cohort of essentially parallel, straight virtual lines extending over the total area of the structured area (8).
