Claim Text:
1. A liquid cyanate ester-epoxy composite resin composition, comprising: (A) cyanate ester resin, (B) epoxy resin, and C) latent curing agent, wherein the amount of the component (B) is 1-10000 mass parts relative to 100 mass parts of the component (A), and the amount of component (C) is 5-60 mass parts relative to 100 mass parts of the total amount of components (A) and (B), wherein said latent curing agent (C) comprises a modified amine (a), which has one or more amino groups having active hydrogen within a molecule, obtained by a reaction of a polyamine compound (a-1) with an epoxy compound (a-2), and a phenol resin (b), and wherein said polyamine compound (a-1) is at least one polyether polyamine compound selected from polyether polyamines represented by the following formulae (0-1)-(0-2): wherein wherein and/or said epoxy compound (a-2) is a polyglycidyl polyether compound having two epoxy groups within a molecule, represented by the following formula (0-7) wherein a and b are each, independently, a number of 1-20, c is 0 or 1, Rp is a hydrogen atom or a methyl group, Rk and Rm are each, independently, an unsubstituted or fluorine-substituted bivalent hydrocarbon group having 1-10 carbon atoms, and Rl is a group represented by any of the following formulae: wherein Rr, Rs, Rt and Ru are each, independently, a hydrogen atom, or an unsubstituted or fluorine-substituted methyl group, d is an integer of 4-12, Rq is —O—, —S—, a single bond or a group represented by formula (0-7b)  wherein
