Provided is a thermosetting resin composite having excellent heat resistance, flame retardancy, mechanical properties, and dimensional stability. Also provided is a cured product of said thermosetting resin composite. The thermosetting resin composite contains a polyimide resin and boron compounds represented by general formulas (b1), (b2), and (b3). (Each R 1 independently represents a hydrogen atom, a C 1–4 alkyl group, or a C 1–4 alkoxy group. Each R 2 independently represents hydrogen, a C 1–4 alkyl group, or a C 1–4 alkoxy group. Y represents a nitrogen-containing heterocyclic compound. Each R 3 independently represents a hydrogen atom, a C 1–4 alkyl group, or a C 1–4 alkoxy group. Z represents a nitrogen-containing heterocyclic compound.) |
