A light emitting device comprises a light emitting layer section having a double heterostructure of an n-type cladding layer, an active layer and a p-type cladding layer, each composed of AlGaInP stacked in this order. Supposing a bonding object layer having a first main surface side as p type and a second main surface side as n type, a light extraction side electrode is formed to cover the first main surface partially. An n-type transparent device substrate composed of Group III-V compound semiconductor having greater band gap energy than the active layer is bonded to the second main surface of the bonding object layer. On one sides of the transparent device substrate and the bonding object layer, a bonding surface to the other is formed, and an InGaP intermediate layer is formed to have a high concentration Si doping layer formed on the bonding surface side.
