    Abstract: PURPOSE:To obtain the title composition which has excellent heat resistance in soldering, moldability, and solvent resistance, and enables resin-sealed semiconductor equipment to be produced, by adding a silane-coupling agent of a specific chemical structure together with a styrene-block copolymer to an epoxy resin. CONSTITUTION:The subject composition comprises (A) an epoxy resin, (B) a curing agent, (C) a styrene block copolymer, (D) an amino group-containing silane coupling agent and (E) a filler. It is preferred that the component (D) is a silane compound in which all of the amino groups are secondary, the proportion of component (E) is 75 to 90wt.% based on the total weight, and component (E) is a fused silica which is composed of 90 to 40wt.% of fused and crushed silica of less than 12mum average particle size and pref. containing 10 to 60wt.% of spherical fused silica of less than 40mum average particle size.
