A supporting plate is described for a filter in a fluid filter device, said filter being essentially perpendicular to the flowing direction of the fluid, said supporting plate containing a large number of holes which pass from the front side of the plate to the rear side. Each hole (8) provides in the area of the front side (6) and/or in the area of the rear side (7) a distal section (16, 17) which is increased relative to the smallest cross-section of the hole (8), whereby this distal section (16, 17) is of such a shape, that the total surface of the edges (13, 14) between the holes (8) is decreased.
