1. A functional element for flat seals, comprising:
a functional material layer with flat outer sealing surfaces and a sieve region in which through openings for the passage of a fluid are arranged lying exposed between threads of a woven or plaited fabric, the woven or plaited fabric extending at least in the sieve region and between the flat outer sealing surfaces;
wherein, in a sealing region formed to be cross-sectionally impermeable, the through openings of the woven or plaited fabric are filled by a compressed filling material and are thereby closed;
wherein the filling material closing the through openings includes a layer or film of supplemental filling material, supplemental to the woven or plaited fabric, pressed into the woven or plaited fabric, the compressed filling material closing the through openings of the woven or plaited fabric and filling spatial regions of the woven or plaited fabric adjoining the threads.
