Abstract
Provided is an optical semiconductor apparatus including an optical semiconductor device; a light-permeable buffer layer that contains a cured high-hardness silicone resin, that has a thickness ranging from 1 μm to 300 μm, and that covers at least part of a light-emitting surface of the optical semiconductor device; and a flexible sealing layer containing a cured flexible silicone resin that has a lower hardness than the light-permeable buffer layer, and that covers the optical semiconductor device and the light-permeable buffer layer. The optical semiconductor apparatus has superior heat resistance and UV resistance and is significantly prevents the breakage of a wire electrically connected to the optical semiconductor device.
