Abstract

A filter element (1) has first and second end sections (3A, 3B) of a flat filter medium which are secured to one another. A sheathing (4) is provided, wherein said sheathing is compressed by the end sections (3A, 3B) and surrounds the end edges (9) of the end sections (3A, 3B). Alternatively, the filter element (1) has first and second end sections (3A, 3B) of a flat filter medium, wherein the first end section (3A) has a fold (5) having two fold legs (6A, 6B). The end section (3B) of the second end section (2B) is then compressed between the fold legs (6A, 6B).
