Abstract
A light emitting device includes a semiconductor light emitting element and a package that seals the semiconductor light emitting element. The package includes a base having a first upper surface region directly or indirectly supporting the semiconductor light emitting element, and a second upper surface region surrounding the first upper surface region in a plan view viewed in a direction normal to the first upper surface region. The package further includes a cover bonded to the base, an inner metal layer disposed on the second upper surface region of the base, an outer metal layer extending along the outer edge of the inner metal layer, and a slit part on the second upper surface region between the inner metal layer and the outer metal layer. In the plan view, the inner edge of the inner metal layer is positioned inward of the outer edge of the cover. In the plan view, at least a portion of the outer edge of the outer metal layer is positioned outward of the outer edge of the cover. The cover is bonded to the base via a bonding material disposed on the inner metal layer.
