Patent ID: 8115192

Claim:
A light emitting device comprising: a substrate; a p-side electrode; a stacked body including at least a light emitting layer made of In x (Al y Ga 1-y ) 1-x P (0≦x≦1, 0≦y≦1), a p-type cladding layer made of In x (Al y Ga 1-y ) 1-x P 0≦x≦1, 0≦y≦1), a p-type current diffusion layer made of In x Al y Ga 1-y ) 1-x P(0≦x≦1, 0≦y≦1) or GaP, and a contact layer, the current diffusion layer being provided between the p-side electrode and the p-type cladding layer; a first metal layer provided on the contact layer and being capable of reflecting emission light from the light emitting layer; and a second metal layer provided on the substrate and bonded to the first metal layer, the p-type cladding layer being located more distant from a bonding interface between the first metal layer and the second metal layer than the light emitting layer, and the p-type cladding layer having a carrier concentration of 0.5×10 17 cm 3 or more and 3×10 17 cm 3 or less.
