Patent ID: 7141825

Claim:
A semiconductor light emitting device comprising: a luminous lamination structure including a first layer made of n-type nitride semiconductor and a second layer made of p-type nitride semiconductor and disposed over the first layer, wherein a luminous region is defined between the first and second layers and the second layer is removed to expose the first layer in a first area which is a partial surface of the first layer; a p-side electrode disposed on a surface of the second layer and electrically connected to the second layer; an insulating film covering the p-side electrode; an n-side electrode electrically connected to the first layer in the first area; a reflection film disposed on the insulating film, extending to the n-side electrode, electrically connected to the n-side electrode, and made of a silver containing alloy or silver; and a conductive layer which is formed on a surface of the reflection film, and which is made of a metal having a larger ionization tendency than an ionization tendency of the reflection film.
