In the state of clamping at least the sheet-like filter element by the inlet side flexible container and the exit side flexible container, the vicinity of the peripheral edge part is welded so as to be integrated with the flexible container over the entire periphery, the oulet side flexible container is formed of the flexible sheet with emboss-like recesses and projections, and the height of the recesses and projections is &ge0.5 mm and &le2.0 mm.
