Abstract:
1. A heat-curable silicone resin-epoxy resin composition comprising: (A) a heat-curable silicone resin represented by an average composition formula (1): wherein R 1 represents identical or different organic groups of 1 to 20 carbon atoms, R 2 represents identical or different organic groups of 1 to 4 carbon atoms, and a, b, and c are numbers that satisfy 0.8≦a≦1.5, 0≦b≦0.3, and 0.001≦c≦1.0, respectively, provided that 0.8≦a+b+c<2, (B) a combination of a triazine derivative epoxy resin (B-1) and an acid anhydride (B-2), or a prepolymer obtained by reaction of a triazine derivative epoxy resin (B-1) and a acid anhydride (B-2) (C) an inorganic filler, and (D) a curing accelerator, wherein a mass ratio of component (A)/component (B) is within a range from 5/95 to 95/5, and wherein an amount of component (C) is within a range from 100 to 1,000 parts by mass per 100 parts by mass of a combination of component (A) and component (B).
