Abstract

A semiconductor light-emitting device includes a semiconductor layer, having a major surface and generating light, a light transmitting layer, having alight transmitting property and covering the major surface of the semiconductor layer, a light reflecting layer, having a light reflecting property and covering the light transmitting layer, and a bonding material diffusion region, formed in a surface layer portion of the light reflecting layer in a boundary portion between the light transmitting layer and the light reflecting layer and having an element having a property of being high in adhesion force with respect to the light transmitting layer more so than an element constituting the light reflecting layer.
