| titleOfInvention | Porous film, separator for secondary battery and secondary battery |
| abstract | PROBLEM TO BE SOLVED: To provide a porous film suitable for a separator for a secondary battery, which has an adhesive function between a separator and an electrode and does not impair the life of the battery. SOLUTION: A porous membrane base material made of a polyolefin, a first porous layer provided on at least one surface of the porous membrane base material made of a polyolefin, and the same film surface via an interface with the first porous layer. The first porous layer contains inorganic particles and a thermoplastic polymer, and the second porous layer contains an adhesive resin, and the second porous layer is provided with respect to the entire surface of the film. A porous film in which the abundance area ratio of the quality layer is 5% or more and less than 55%, and the adhesive resin contained in the second porous layer adheres to the electrode.
