Abstract
A filter element for filtering a fluid has a zigzag-shaped folded filter medium with fold edges neighboring each other. A thread is attached by an adhesive material to the fold edges. The thread is a multiple-wound yarn. In a method for manufacturing the filter element, a thread in the form of a multiple-wound yarn is attached by an adhesive material to fold edges of a zigzag-shaped folded filter material. In the method, the thread is soaked and/or coated with the adhesive material that is in a plastic state. The thread soaked and/or coated with the adhesive material is attached to the fold edges by applying a pressure, and the adhesive material is hardened.
