PURPOSE: To obtain the subject composition excellent in fluidity in molding and crack resistance and useful for cured material by blending a composition consisting essentially of an epoxy resin, a curing agent and an inorganic filler with a specific silanol-containing silicon compound. CONSTITUTION: This resin composition is obtained by blending an epoxy resin composition containing (A) an epoxy resin (preferably an epoxy resin of formula I), (B) a curing agent (preferably a phenol novolak resin) and (C) an inorganic filler (preferably crushed or globular fused silica having 5-40μm average particle diameter) with (D) a silanol group-containing silicon compound of formula II [R is a monovalent hydrocarbon; (n) is 1 or 2] (especially preferably 1,1,3,3- tetramethyl-1,3-dihydroxydisiloxane) in an amount of 0.05-0.3wt.% based on total amount of the composition.
