Abstract

A flat filter element (34), a filter (10), and a support/positioning body (72, 74, 76) are disclosed. The flat filter element (34) includes a filter medium (64) with an inflow-side raw side (62) and an outflow-side clean side (58). An element sealing section (77) surrounds, circumferentially closed, the filter medium (64) on the raw side (62), the clean side (58), or between the raw side (62) and the clean side (58). The element sealing section (77) serves for supporting a sealing device (78) for sealing the raw side (62) relative to the clean side (58) upon arrangement of the flat filter element (34) in a filter housing (12) of the filter (10). At least one support/positioning body (72, 74, 76) can be supported, for positioning and holding at least the sealing device (76) in the filter housing (12), on the one hand at least on the sealing device (78) and on the other hand on the filter housing (12).
