Abstract

A flat gasket with at least one extended carrier layer is described. Such flat gaskets are for instance used as transmission plates or also as cylinder head gaskets. They are also used in the area of the exhaust line of a combustion engine. The at least one extended carrier layer has a first surface and a second surface opposite to the first surface. The layer also has a passage opening for a fluid which penetrates the carrier layer. The circumferential edge of each of the two surfaces has one or several projections which encircle the passage opening at least in sections and protrude into the passage opening. A functional element is arranged in the passage opening, which is held by the one or several projections in the passage opening.
