PROBLEM TO BE SOLVED: To provide an epoxy resin adhesive composition which controls short wavelength-wave absorption, is excellent in ultraviolet resistance, weather resistance, reflexivity and storage stability, has an excellent coatability for use in assemblies of semiconductor devices mounting optical semiconductor chips and bonding various kinds of components and shows excellent light reflexivity and an adhesive for an optical semiconductors using the composition. SOLUTION: The light-reflecting epoxy resin adhesive composition indispensably contains (A) an alicyclic epoxy compound, (B) a silane compound containing a hydrolyzable group directly coupling with a silicon atom, (c1) a divalent organic tin compound, (c2) a quadrivalent organic tin compound and (D) a light-reflecting inorganic filler. The contents of the components are; (A): 1-90 wt.%, (B): 0.1-15 wt.%, (c1): 0.01-5 wt.%, (c2): 0.01-5 wt.% and (D): 3-90 wt.% each based on the total amount of the composition.
