A semiconductor light-emitting device is provided with a semiconductor layer including a first surface, a second surface opposite to the first surface, a luminous layer, and a first electrode formed on the first surface. The first surface has flat and rough portions. The first electrode has a pad and a fine wire electrode that is narrower than the pad. The fine wire electrode is formed on the flat portions but not on the rough portions. One or more metal contacts are disposed on the second surface to be under the rough portions.
