An epoxy resin composition curable to a heat resistant product comprises (i) amino group-terminated imide compound (A) produced by imidating at least one aromatic diamine selected from those of formulae (I), (II) and (III),
wherein R,, R2, R3, R4 and R5 are selected independently from hydrogen and halogen atoms and C1-C5 alkyl, C1-C3 alkoxy and hydroxyl groups and the or each X represents a divalent group selected from
with at least one aromatic tetracarboxylic anhydride at a diamine:anhydride molar ratio of from 1.2:1 to 4:1, and epoxy resin (B) having at least two epoxy groups in the molecule, the molar ratio of the amino group content of imide compound (A) to the epoxy group content of epoxy resin (B) being 1:1.6 to 1:2.6; or (ii) epoxy resin (D) having two or more β-unsubstituted glycidyl groups in the molecule and aromatic amide-imide compound (E) having both an imide and amide groups in the molecule and a terminal amino group.
