| 摘要 |
An optical device of the present invention comprises a light-emitting element or a light-receiving element mounted on a support and a cured silicone material unified into a single article onto the support by the sealing of the element with a hydrosilylation reaction curable silicone composition, and is characterized in that the surface of the cured silicone material has been treated with an organopolysiloxane that has at least three silicon-bonded hydrogen atoms in one molecule. The optical device is resistant to the adherence of dust and dirt due to an inhibition of the stickiness of the surface of a cured silicone material that seals a light-emitting element or a light-receiving element mounted on a support and has thereby been unified into a single body onto the support. |
