Abstract
A semiconductor light-emitting device includes a first bonding pattern made of metal that is formed on a substrate, and a second bonding pattern provided in a base portion and a flange portion of a dome-shaped transparent body. The first and second bonding patterns are bonded to each other via solder, to seal a space in a convex lid portion. The first and second bonding patterns have rectangular ring shapes that surround the semiconductor light-emitting element when viewed from above, at least edges on inner peripheral sides of corner portions thereof are positioned on outer sides of outer peripheral edges of an annular base portion of the convex lid portion, and edges on inner peripheral sides of straight-line portions sandwiched between the corner portions are positioned closer to the semiconductor light-emitting element than the outer peripheral edge of the annular base portion of the convex lid portion.
