摘要： A light emitting device includes a semiconductor multilayer structure having a first semiconductor layer of a first conductivity type, a second semiconductor layer of a second conductivity type, and an active layer. A reflecting layer is provided at one surface of the semiconductor multilayer structure and reflects a light emitted from the active layer. A supporting substrate is provided at an opposite side of the reflecting layer with respect to a side of the semiconductor multilayer structure and supports the semiconductor multilayer structure via a metal bonding layer. An adhesion layer is provided at a surface of the supporting substrate at an opposite side with respect to a side of the metal bonding layer. A back surface electrode of an alloy contacts with a surface of the adhesion layer at an opposite side with respect to a surface contacting to the supporting substrate.
