The supporting grid (11) has multiple webs, which are partially connected with each other, and a hollow-cylindrical grid structure surrounding in a cylindrical interior space. A center opening cross section of the passage openings (13) is greater in an area adjacent to a first axial end of the support grid than in a second area adjacent to a second axial end of the support grid. A fastening unit has a thread (17) for positive fastening in a filter housing at the second axial end. An independent claim is included for a filter element with star-shaped filter bellows. |
