Light emitting device and method for manufacturing the same

摘要

In the production of a light emitting device, in which a plurality of light emitting element parts carrying LED elements are formed on a substrate, and the substrate is diced, generation of shaving dusts is suppressed at the time of the dicing, and breakage of the substrate during the production process is prevented. In the step of forming a slit 24 crossing a region for forming light emitting element part 22 in a metal substrate 20, a recess 21 for serving as resin reservoir is formed so as to cross the slit 24. Then, the slit 24 is filled with an insulating material, the recess 21 is filled with a resin, and they are cured. Thereafter, a light emitting element part is formed in the region for forming light emitting element part 22, the metal substrate is cut into units comprising one or a plurality of the light emitting element parts, and mounted on a printed circuit board on which a pattern is formed.
