    • A thermosetting polyimide resin composition is provided which comprises a polyimide resin and an epoxy resin, which has excellent heat resistance, low dielectric constant and low dielectric loss tangent and also yields a cured article having good mechanical properties such as tensile strength and tensile elongation. Also, a process for producing a polyimide resin used in the polyimide resin composition is provided. The thermosetting polyimide resin composition comprises a polyimide resin (X), which has a carboxyl group and a linear hydrocarbon structure having a number-average molecular weight of 300 to 6,000, and an epoxy resin (Y). The polyimide resin is obtained by reacting a prepolymer (A) having an isocyanate group at the end, which is obtained by reacting a polyisocyanate compound (a1) with a polyol compound (a2) having a linear hydrocarbon structure in which a number-average molecular weight of a linear hydrocarbon structure is from 300 to 6,000, with an anhydride (B) of polycarboxylic acid having three or more carboxyl groups in an organic solvent.
