Abstract
A light-emitting device includes a substrate including a substrate second upper surface provided between a substrate bottom surface and a substrate first upper surface in a height direction. A light-emitting element to emit ultraviolet light is provided on the substrate first upper surface. A protective element includes a protective element upper surface provided between the substrate first upper surface and the substrate second upper surface in the height direction. A frame is bonded to the substrate first upper surface via adhesive members to surround the light-emitting element. The frame includes a frame lower surface opposite to the substrate first upper surface and the substrate second upper surface in the height direction to provide a gap between the substrate first upper surface and the frame lower surface. A space in which the light-emitting element is provided communicates with an outside of the light-emitting device via the gap.
