<p>Filter element (3), pref. a hollow-cylindrical element of zigzag folded configuration around a central axis, is located in a filter housing (2) and has seals (4, 7) at least one end face of the element and on an area of the element abutting a central tube. An elastic material (6) is applied as sealant, having adequate residual elasticity after a curing process and forming a fixant for the fold structure of the element, which is pref. of filter paper. Additional sealing elements may be embedded in the elastic material, which is pref. formed from nitrile rubber and phenolic resin in a mixing ratio of 1:0.8 to 1:1.5.
