PROBLEM TO BE SOLVED: To provide an insulating sheet excelling in easiness of handling in an uncured state, and giving a cured material excellent in dielectric breakdown characteristics, thermal conductivity, and heat resistance. SOLUTION: This insulating sheet contains a polymer (A) having a weight average molecular weight of not less than 10,000, an epoxy monomer (B1) or an oxetane monomer (B2) having a weight average molecular weight of not more than 600, an curing agent (C) which is a phenol resin or an acid anhydride, a water-added product of the acid anhydride or a denatured material of the acid anhydride, a filler (D), and a silane coupling agent (G) having an organic value of 20-320 and an inorganic value of not more than 50 in the organic conceptual diagram of an organic functional group in the formula (21).
