PROBLEM TO BE SOLVED: To provide a method for producing a bag-like hydrophilic porous film having high strength at a joint section in high productive efficiency. SOLUTION: The method for producing the bag-like porous film is to process the plane porous film comprising a thermoplastic resin to have a bag-like shape by fusion, subsequently apply radiation to the porous film and react a hydrophilic monomer to the irradiated film.
