Abstract
A fixing material includes a silane compound polymer as the main component, the silane compound polymer being produced by condensing a silane compound mixture that includes at least one silane compound (1) shown by the following formula (1): RSi(OR)(X)(wherein Rrepresents a group including an ester structure or a cyanoalkyl group, Rrepresents an alkyl group having 1 to 6 carbon atoms or the like, Xrepresents a halogen atom, and p is an integer from 0 to 3), and at least one silane compound (2) shown by the following formula (2): Si(OR)(X)(wherein Rrepresents an alkyl group having 1 to 6 carbon atoms, Xrepresents a halogen atom, and q is an integer from 0 to 4). A sealed optical device includes an optical device that is sealed with a cured product of the fixing material. The fixing material produces a cured product that exhibits high hardness, excellent transparency and heat resistance, and rarely undergoes coloration even when subjected to high-energy light or heat for a long time.
