Abstract:
A light-emitting apparatus of the present invention has (i) a semiconductor device which emits light toward a higher position than a substrate and (ii) a plurality of external connection terminals, and includes: a light-reflecting layer, provided on the substrate, which reflects the light emitted by the semiconductor device; and a covering layer which covers at least the light-reflecting layer and which transmits the light reflected by the light-reflecting layer. Further, the semiconductor device is provided on the covering layer, and is electrically connected to the external connection terminals via connecting portions, and the semiconductor device and the connecting portions are sealed with a sealing resin so as to be covered. Therefore, the light-emitting apparatus has increased efficiency with which light is taken out, and can prevent a reflecting layer from being altered, deteriorating, and decreasing in reflectance.
