Abstract
A filter element for filtering a fluid has a filter body with a filter medium folded in a zigzag shape with folds extending in a fold direction. The filter body has an end edge bonding which seals fold ends of the folds. The filter body has an outer contour with recesses. The end edge bonding, in a region of the recesses of the outer contour of the filter body, is embodied discontinuously. The end edge bonding has at least one outwardly positioned first bonding segment and an inwardly positioned second bonding segment, viewed in the fold direction. The inwardly positioned second bonding segment, in a transverse direction relative to the fold direction, is arranged at a spacing to the at least one outwardly positioned first bonding segment. The at least one outwardly positioned first bonding segment and the inwardly positioned second bonding segment bond at least one common fold.
