Abstract

A flat filter element for filtering a fluid may include a filter body made up of a folded filter material. The filter element may also include a circumferential edge and a side edge running in a circumferential direction along the circumferential edge. The side edge may have at least one strip portion, running along the side edge, with a side strip that may be separate from the filter body and arranged on the filter body. The side edge may also have at least one adhesive portion running along the side edge for sealing the filter body. The at least one adhesive portion may be formed by gluing of least two folds, adjacent along the side edge, in a region of the side edge.
