The invention concerns a filter element for fluids, in particular for hydraulic fluid, consisting of at least one foldable filter casing (10) with at least one filter layer (18, 20, 22, 24), which extends between two end caps (26, 32), characterized in that, in order to vary in regions the thickness of the filter casing (10), the height (h1) of each filter fold (12, 44) increases from one end cap (26) to the other end cap (32) or, with the filter fold height (h1) being maintained, the outer diameter (40) of the filter casing (10) varies in the direction of one of the end caps (26, 32). |
