要約
(EN)
Provided is a production method for porous polyimide resin film having high porosity. This production method for porous polyimide resin film has a fine particle elimination step in which fine particles are extracted from a polyimide resin-fine particle composite film to obtain a porous polyimide resin film, wherein the method has a polyimide resin elimination step in which either at least a portion of the polyimide resin section of the polyimide resin-fine particle composite film is eliminated prior to the fine particle elimination step, or at least a portion of the polyimide resin section of the polyimide resin-fine particle composite film is eliminated subsequent to the fine particle elimination step.
