<p>The polyimide resin composition of the present invention at least comprises a polar solvent and a polyimide resin, where the viscosity-average molecular weight of the polyimide resin is 0.6 to 1.60. 95 to 100 mol% of total monomer of the polyimide resin is an aromatic monomer including no aliphatic chain having 3 or more carbon atoms on the main chain, where the aromatic monomer includes a monomer (A) having at least one benzophenone skeleton represented either by chemical formula (1) or (2) in an amount of 5 to 30 mol% in the total monomer, a monomer (B) having a diphenyl ether skeleton, which is free of a biphenyl skeleton, in an amount of 40 to 95 mol% in the total monomer, and a monomer (C) having a biphenyl skeleton in an amount of less than 45 mol% in the total monomer, and 20 to 95 mol% of the monomer (B) in the total monomer constituting the polyimide resin has three or more aromatic rings.</p> |
