Abstract: A nonwoven fabric is formed of fibers of 0.10 μm or more and 5.00 μm or less. The nonwoven fabric includes a coarse layer portion and a dense layer portion. In the coarse layer portion, a void volume Pc is at least 90% and an average pore diameter Dc is in a range of 0.5 μm or more and 50 μm or less. In the dense layer portion, a void volume Pd is at least 70% and a relative standard deviation of pore diameter distribution is 20% or less.

Abstract: There are provide a cell separation filter with which cells can be separated without damage and can suppress adsorption, a filtering device, and a manufacturing method for a cell separation filter. The cell separation filter is composed of a nonwoven fabric that is formed of fibers containing a water-insoluble polymer and a hydrophilizing agent and has a fiber density difference in the film thickness direction. The nonwoven fabric has an average through-hole diameter of 2.0 μm or more and less than 10.0 μm, a void ratio of 75% or more and 98% or less, a film thickness of 100 μm or more, and a critical wet surface tension of 72 mN/m or more.

Abstract: There is provided a liquid filter having a small pressure loss and a manufacturing method for a liquid filter. The liquid filter is a liquid filter that is composed of a nonwoven fabric formed of fibers containing a water-insoluble polymer and a hydrophilizing agent. In the nonwoven fabric, a fiber density continuously changes in a film thickness direction, a fiber density difference is present in the film thickness direction, the fiber density of one surface of the nonwoven fabric in the film thickness direction is maximal, and the fiber density of the other surface of the nonwoven fabric in the film thickness direction is minimal.
