摘要:
Provided is a porous film that can contribute to improving the cycle characteristics of an electric cell by improving binding characteristics, for a porous film provided on a surface of an electrode used in a secondary cell and the like. The porous film comprises a water-soluble polymer, an inorganic filler, and a water-insoluble particulate polymer including 0.5-40 mass % of a monomer unit having a hydrophilic group selected from the group consisting of carboxylic acid groups, hydroxyl groups, and sulfonate groups.
