A semiconductor light emitting device includes a semiconductor layer, a p-side and an n-side interconnect portions, a fluorescent substance layer and a transparent layer. The semiconductor layer has a first major surface, a second major surface, and a first side surface, the semiconductor layer including a light emitting layer. The p-side and n-side interconnect portions are electrically connected to the semiconductor layer. The fluorescent substance layer is provided on the first major surface side. The transparent layer is provided between the semiconductor layer and the fluorescent substance layer, and has a second side surface. The device further includes an insulating film covering the first side surface and the second side surface, and a reflecting member covering the first side surface and the second side surface via the insulating film.
