A filter element ( 10 ) having a supporting body ( 11 ) around which a filter medium ( 12 ) is wound. The filter medium ( 12 ) is a weldable material and is sealingly affixed to the supporting body ( 11 ) two radial weld seams ( 18 ) and/or a longitudinal weld seam ( 19 ). The welding of the filter medium ( 12 ) onto the supporting body ( 11 ) eliminates the need to produce prefabricated tubes of filter medium, and enables the filter medium to be processed directly from a roll.
