A filter element 10 for purifying fluids having a filter medium 11, an enclosure member 12, and a rod 13. The filter medium 11 has folds 14, which may be zigzag-shaped, and which define a fold height 15 and a pleat surface 16. At right angles to folds 14 extend end faces 17, which represent the course of the folds 14. The enclosure members 12 are arranged on the end faces 17. To support the folds 14, the rod 13 pierces through the pleat surfaces 16 of the folds 14 creating joints 19. These joints 19 are sealed, e.g., by additional seals or by fusing the filter medium to the support rod or the support rod to the filter medium.
