Abstract
A curable silicone composition encapsulates, coats, or adheres an optical semiconductor element. The curable silicone composition can form a cured product with sufficiently low gas-permeability, and with little weight decrease and little change in hardness even on long-term exposure to high temperatures. The curable silicone composition comprises resinous organopolysiloxane that contains at least one (ArSiO) unit, wherein Ar denotes an aryl group.
