Abstract
In order to further develop a filter element, in particular for the filtration of mineral oils in hydraulic systems, having a filter material and a support tube which supports the filter material and is formed from a perforated plate with a multiplicity of flow openings, in such a manner that it is highly mechanically stable and can be produced at low cost, it is proposed, according to the invention, that the support tube has a joint which extends helically along the support-tube wall and is formed by those edges of the perforated plate which are in contact with one another in the circumferential direction.
