Abstract:
There is provided a method for producing a porous polyimide film, including a first step of forming a coating film containing a polyimide precursor solution where a polyimide precursor and an organic amine compound are dissolved in an aqueous solvent, and a resin particle incapable of dissolving in the polyimide precursor solution, followed by drying of the coating film to form a coat containing the polyimide precursor and the resin particle, and a second step of heating the coat to imidize the polyimide precursor and form a polyimide film, the second step including a treatment for removing the resin particle.
