A filter for a fluid-conducting pipe, in particular for a gas-conducting pipe of an internal combustion engine. The filter includes a self-supporting areal filter element and is fixable along a circumferencedirectly or indirectly in the pipe and, in so doing, covers a free cross section of the pipe. Here, the circumferenceof the filter elementcircumscribes a central filter plane. Furthermore, the filter elementor at least one layer thereof is comprised of a plastically deformable material and is provided with at least one undulationor bead, which does not intersect the circumference, in such a way that the filter elementintersects the filter plane, or a planeparallel thereto, at least four times within the circumference
