Abstract
The invention relates to a filter element (50), in particular for a tank breather filter (10), the filter element (50) being produced from a flat filter material. To form the filter element (50) in such a way that it can be produced at low cost, it is proposed that it is made in one piece and has an end wall (51), which is surrounded by a corrugated side wall (52) aligned at an angle with respect to the end wall (51). A method for producing a filter element of this kind (50) and a tank breather filter (10) with a filter element of this kind (50) are also proposed.
