PURPOSE:To obtain thee titled composition having excellent water-vapor resistance, improved moldability and appearance of molded article, by blending a specific epoxy resin with a curing agent, an inorganic filler and a rubber-like resin. CONSTITUTION:(A) An epoxy resin shown by the formula (n is 0-2) is uniformly blended with (B) a curing agent for an epoxy resin (e.g. phenolic novolak resin, etc.), (C) an inorganic filler (e.g. silica powder, antimony oxide, etc.) and (D) a rubber-like resin (e.g. natural rubber, synthetic rubber, etc.) to give the aimed composition. The blending ratio of the components is preferably 1-100pts.wt. curing agent B and 5-30pts.wt. rubber component D based on 100pts.wt. resin A And 60-85wt.% filler C based on sum of the composition. The composition may be optionally mixed with a curing promoter, a flame-retardant, an internal mold release agent, a coupling agent, pigment, etc.
