At least one light-emitting element 21 is mounted on the base member 22, and the base member 22 electrically connects the light-emitting device 200 to an external device. The base member 22 is a plate and includes the wiring 26 on the surface of and/or inside the base member 22. The base member 22 has a substantially square outer shape in a plan view. A material similar to a material used for the base member 2 can be used for the base member 22. Similarly to the base member 2, the base member 22 has a lower surface, and may include, on the lower surface of the base member 22, a heat dissipation terminal electrically independent of the light-emitting elements 21.

Protruding Part

An insulating material that is less likely to transmit light emitted from the light-emitting elements 21 and extraneous light is preferably used for the protruding part 27. A material with predetermined strength is preferably used for the protruding part 27. Specific examples of the protruding part 27 include ceramics such as alumina, aluminum nitride, and mullite, and resins such as phenolic resins, epoxy resins, silicone resins, polyimide resins, bismaleimide-triazine resins (BT resins), polyphthalamide (PPA), polyamides (PA), and unsaturated polyesters. The protruding part 27 may have any appropriate height.

The height of the protruding part 27 is in the range of 0.1 mm to 5 mm, preferably 0.3 mm to 2 mm.
