PROBLEM TO BE SOLVED: To provide a cured product with extremely small change of physical property in a reliability test, excellent in mechanical property, electrical property, insulating property, heat resistance, thermal shock resistance and reliability, and to provide a thermosetting resin composition imparting the cured product. SOLUTION: The thermosetting resin composition comprises (A) an epoxy resin, (B) a crosslinked diene-based rubber containing <10 wt.% of bonded acrylonitrile, (C) an antioxidant, (D) a curing agent and (E) a curing catalyst. Wherein the diene-based crosslinked rubber (B) is preferably a copolymer of a crosslinking monomer having at least two polymerizable unsaturated bonds and excluding acrylonitrile.
