Abstract:
1. A manufacturing method of a light-emitting device, comprising: a die-bonding process in which a semiconductor light emitting element is placed on a bonding target member via an adhesive containing a silicone resin such that a surface of the semiconductor light emitting element opposite to an exposure surface faces the bonding target member, and the adhesive is heated to bond the semiconductor light emitting element to the bonding target member, the semiconductor light emitting element including a semiconductor layer including a light emitting layer that emits light by passing a current, and an electrode including a metal layer composed of a metallic material containing Au and provided on the semiconductor layer and a covering layer composed of a material containing Ni or Ta and covering the metal layer, a thickness of the covering layer being set smaller than 100 nm and the exposure surface for exposing the covering layer to an outside being formed; and a wire-bonding process in which a wire is connected to the exposure surface in the electrode of the semiconductor light emitting element bonded to the bonding target member.
