    Abstract: To provide a porous polyimide resin film having a high aperture ratio. A method for producing a porous polyimide film comprising removing fine particles from a polyimide resin-fine particle composite film to thereby obtain a porous polyimide resin film, in which the method comprises either removing at least a part of a polyimide resin portion of the polyimide resin-fine particle composite film prior to removing the fine particles, or removing at least a part of the porous polyimide resin film subsequent to removing the fine particles.

    Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a porous film with high heat resistance in an easy process at a low cost. SOLUTION: The method for producing a porous film containing liquid-crystalline polyester is characterized by comprising the following steps (a), (b) and (c) in this order. (a) 100 Parts by weight of a liquid-crystalline polyester is dissolved in a solvent and 1 to 1,500 parts by weight of a filler with respect to 100 parts by weight of the liquid-crystalline polyester is dispersed in the solution to prepare a slurry coating fluid. (b) The coating fluid is applied to at least one side of a substrate to form a coating film. (c) The coating film is subjected to solvent removal, immersion in a solvent in which the liquid-crystalline polyester does not dissolve, and drying to thereby obtain a porous film containing the liquid-crystalline polyester.
