Abstract

The invention relates to a filter element consisting of a filter medium (10) that is pleated in a zigzag manner and has a concentric shape, and a first end disk (11) and a second end disk (12) disposed on an opposite front, wherein the end disk (12) has a concentric opening (13) and extends substantially annularly across the pleats of the filter medium. The end disk (11) has a ring collar (14) extending radially toward the outside. Said ring collar (14) has a seal (15) that surrounds the ring collar at least partially, wherein the seal has an axially extending region, which carries radially peripheral sealing lips (17), and said radially peripheral sealing lips are supported in a groove (18) or in a housing wall (19) of a housing receiving the filter element.
