PROBLEM TO BE SOLVED: To provide a composite resin having high heat resistance, a resin composition containing the same, a cured product obtained by curing the resin composition, and a heat resistant material containing the cured product. The above-mentioned problems are solved by providing a composite resin (A) having a specific polysiloxane segment (a1) having an epoxy group and a vinyl polymer segment. Moreover, the said subject is solved by providing the hardened | cured material formed by hardening | curing the said composite resin, and the heat-resistant material containing this hardened | cured material.
