Abstract

A filter element (12), particularly for the intake air of an internal combustion engine. The filter element (12) has a filter body (13) and a seal (15) disposed circumferentially around the filter body (13). The seal (15) is bonded to the filter body (13) with an adhesive (31) and includes a hard component (26) and a soft component (27). The hard component (26), which rests directly on a housing section, prevents the filter element (12) from moving relative to this housing section, and since the filter element cannot move relative to the housing section, damage to the filter element is avoided.
