Summary:PROBLEM TO BE SOLVED: To provide a nonwoven fabric laminated liquid fabric filter where the collection property and collection accuracy of an object having submicron particle sizes are increased capable of preventing the object of size to be collected that probably passes through a filter from passing through the filter in particularly collecting the object having a submicron particle size with a filter using a nonwoven fabric that is problematic in collection accuracy because pore diameters are uneven.SOLUTION: The nonwoven fabric rolled type filter filters solid matter in liquid, wherein in the major filtration layer, the average fiber diameter is 0.2 to 1.0 μm, the basis weight is 50 to 300 g/m, the porosity is 55 to 85%, the average stream flow pore diameter is 0.3 to 2.0 μm, and is one where a nonwoven fabric within 200% of dispersion in diameter of opening is rolled several times.
