    摘要: 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.
