In the case of a filter or catalyst body comprising wires or fibres which are constructed in a single-layer or multi- layer as woven cloth, braiding or knitted fabric, the wires or fibres (1) are at least partially connected to one another by sintering or welding. The woven cloth, braiding or knitted fabric is endowed with inserted powdery, granular or chip-like particles (2), which are sintered with the wires or fibres (1), with the filter density being lower in the inlet region (3) of the filter body as fewer particles are provided there.
