The invention is to provide a filtration membrane for oleophilic organic liquids, which has reduced filtration resistance and increased filtration efficiency and of which the filtration capacity can be freely designed, to provide a method for producing the membrane, and to provide a method for filtering oleophilic organic liquids. The filtration membrane 3 is made of an oleophilic polymer material having a three-dimensional crosslink structure. The oleophilic polymer material is in a gel-like or dry glue-like condition. The inter-crosslink spaces 10 in the three-dimensional crosslink structure are filled with molecules 2 of an oleophilic organic liquid capable of passing through the spaces. Desirably, the inter-crosslink spaces in the three-dimensional crosslink structure are larger than the molecule of the oleophilic organic liquid but are not larger than 1000 nm in terms of their mean diameter. Also desirably, the oleophilic polymer material is supported by a support. <IMAGE> |
