PROBLEM TO BE SOLVED: To provide a white curable composition for an optical semiconductor device where migration hardly occurs at a metal part in the optical semiconductor device which includes a compact obtained by molding of the white curable composition for the optical semiconductor device.SOLUTION: A white curable composition for an optical semiconductor contains an epoxy compound, a curative agent, a titanium oxide, a filler different from the titanium oxide, a hardening accelerator, and an antioxidant. A molecular mass of the antioxidant is 600 or larger and less than 2000. Constituent atoms of the antioxidant are only three kinds, a carbon atom, an oxygen atom, and a hydrogen atom.SELECTED DRAWING: Figure 1 |
