Disclosed is a liquid epoxy resin composition comprising (A) a liquid epoxy resin, (B) a dimethylpolysiloxane having epoxy groups at its both ends, and (C) a dispersing agent comprising the reaction product of (C-1) a dimethylpolysiloxane having amino groups or carboxyl groups reactive with epoxy resins at its side chains or both ends and having phenyl groups or polyether groups for improving its compatibility with epoxy resins at its side chains, and (C-2) an epoxy resin having the same structure as the component (A). The composition has a reduced internal stress, while maintaining the heat resistance intrinsic to epoxy resins, and has excellent resistance, crack resistance and heat shock resistance.
