Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyimide resin which is soluble in an organic solvent and has a low water-absorption coefficient, excellent thermoplasticity, high heat resistance, and also excellent adhesion properties.SOLUTION: In a method for producing a polyimide resin, the polyimide resin includes a repeating unit derived from polyamide acids (1) and (2) obtained by the reaction of a tetracarboxylic acid component, such as 1,2,4,5-cyclohexane tetracarboxylic dianhydride and pyromellitic dianhydride, and a diamine component, wherein the diamine component is at least one selected from the group consisting of a diamine represented by NH2-X-NH2 and a reactive derivative thereof, and includes at least one selected from the group consisting of 2,2-bis[4-(4-aminophenoxy)phenyl]propane and a reactive derivative thereof, with a ratio of at least 50 mol% (including 100 mol%).
