摘要

A surface-emitting semiconductor array device includes a substrate (100), a plurality of light-emitting portions (102), an electrode pad portion (106) formed on the substrate (100) and disposed through the plurality of light-emitting portions and a dividing groove (104), and having a plurality of electrode pads (108) formed on an insulating film, and a plurality of metal wirings (110) for connecting each of the plurality of light-emitting portions (102) to a corresponding electrode pad (108) through the dividing groove (104), the dividing groove (104) has a wave-shaped side wall formed on the substrate (100).
