    • PROBLEM TO BE SOLVED: To provide a prepreg and a laminate sheet showing a small reduction in the thermal conductivity when a glass fiber fabric is impregnated with a resin composition, and having low thermal expansion property.SOLUTION: The prepreg is obtained by impregnating and coating a glass fiber base material with a resin composition that comprises an epoxy resin having a specified structure as a thermosetting resin and a polyimide resin having a specified structure as a hardening agent. In the resin composition, the content of the epoxy resin having the specified structure is 30 to 50 mass%. The resin composition further contains an inorganic filler; the content of the inorganic filler is 30 to 70 vol% with respect to the whole resin composition; and the inorganic filler contains at least aluminum oxide.
