A semiconductor light-emitting device includes a light-emitting structure that includes a first conductive semiconductor layer, an active layer, a second conductive semiconductor layer, an electrode layer contacting one of the first conductive semiconductor layer and the second conductive semiconductor layer, and a bonding conductive layer connected to the electrode layer. The bonding conductive layer includes a main bonding layer having a recess area defined by a stepped portion on a surface opposite to a surface facing the electrode layer, and a filling bonding layer filling at least a part of the recess area.
