Abstract:
Provided are: a filtration filter in which a porous resin can be strongly and reliably held by a support, and by which the amount of permeable water can be increased while maintaining a blocking rate of impurities; and a method for producing same. Provided are a filtration filter capable of filtering impurities, and a method for producing same, wherein a support having a fibrous structure is impregnated with a resin solution prepared by dissolving a predetermined resin in a predetermined solvent, and is then immersed in a non-solvent solution to perform replacement between the solvent of the resin solution and the non-solvent solution, thereby obtaining a filtration filter in which a filtration membrane, which is composed of a porous resin and can filter impurities, is integrally formed inside the support.
