ABSTRACT:
There is provided a semiconductor light-emitting device having excellent light extraction efficiency and low wavelength unevenness, a manufacturing method thereof, and a lamp. A semiconductor light-emitting device includes an n-type semiconductor layer12, a light-emitting layer13, a p-type semiconductor layer14, and a titanium oxide-based conductive film layer15laminated in this order, wherein a random concavo-convex surface15is formed on at least a part of the surface of the titanium oxide-based conductive film layer.
