Abstract
In the semiconductor light emitting device of the present invention, a reflective layer for reflecting light emitted by a semiconductor light emitting element is formed on a Cu wiring pattern, and a bonding section is formed on a light-emitting-element-mounting area on the Cu wiring pattern, to which an electrode of an LED chip is connected, the bonding section being made of a material allowing the semiconductor light emitting element to be soldered on the reflective layer without flux. Consequently, it is possible to realize a high-quality semiconductor light emitting device which has a semiconductor light emitting element firmly attached to a bonding surface and which is capable of emitting light while reducing deterioration in luminosity and color tone shift.
