Abstract

Disclosed is an insulating sheet which is used for bonding a heat conductor having a thermal conductivity of not less than 10 W/m•K to an electrically conductive layer. This insulating sheet has excellent handling properties in an uncured state, and a cured product of this insulating sheet is improved in adhesiveness, heat resistance, dielectric breakdown characteristics and thermal conductivity. Specifically disclosed is an insulating sheet used for bonding a heat conductor having a thermal conductivity of not less than 10 W/m•K to an electrically conductive layer, which sheet contains (A) a polymer having an aromatic skeleton and a weight average molecular weight of not less than 10,000, (B) a monomer composed of at least one of (B1) an epoxy monomer having an aromatic skeleton and a weight average molecular weight of not more than 600 and (B2) an oxethane monomer, (C) a curing agent composed of a phenol resin, an acid anhydride having an aromatic skeleton or an alicyclic skeleton, a hydrogenated product of such an acid anhydride or a modified product of such an acid anhydride, and (D) a filler. This insulating sheet has a glass transition temperature Tg in an uncured state of not more than 25˚C.
