Light-emitting device

A light-emitting device comprising:

• a substrate comprising:
• a substrate bottom surface;
• a substrate first upper surface opposite to the substrate bottom surface in a height direction of the light-emitting device;
• and
• a substrate second upper surface opposite to the substrate bottom surface in the height direction, the substrate second upper surface being provided between the substrate first upper surface and the substrate bottom surface in the height direction;
• a light-emitting element to emit ultraviolet light provided on the substrate first upper surface;
• a protective element provided on the substrate second upper surface, the protective element comprising:
• a protective element lower surface facing the substrate second upper surface;
• and
• a protective element upper surface opposite to the protective element lower surface in the height direction, the protective element upper surface being provided between the substrate first upper surface and the substrate second upper surface in the height direction;
• adhesive members provided on the substrate first upper surface to surround the light-emitting element;
• a frame bonded to the substrate first upper surface via the adhesive members to surround the light-emitting element, the frame comprising:
• a frame lower surface being 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 communicating with an outside of the light-emitting device via the gap;
• and
• a frame upper surface opposite to the frame lower surface in the height direction;
• and
• a light-transmissive member provided on the frame upper surface.
