摘要

PROBLEM TO BE SOLVED: To provide a method of producing a polyimide molding whose imidization is efficiently promoted.SOLUTION: The method of producing a polyimide molding heat-treats and molds a polyimide precursor composition in which a resin which has a repeating unit represented by general formula (I) and has an imidization ratio of 0.2 or less and an aliphatic cyclic amine compound are dissolved in an aqueous solvent. In the general formula (I), A represents a tetravalent organic group, and B represents a divalent organic group.
