Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a light-emitting device with improved adhesion between a heat radiation member and a substrate on which a light source is mounted, especially the vicinity of the light source, excellent heat radiation property on the light source, and high reliability. SOLUTION: The light-emitting device 100 includes a heat radiation member 40, a substrate 20 which is placed on the heat radiation member 40 and includes a plurality of light sources 10 arrayed with a distance d on an upper surface, a cover member 30 which is held by the heat radiation member 40 to cover the substrate 20, and a presser member 50 which is interposed between the substrate 20 and the cover member 30 to press the substrate 20 against the heat radiation member 40. The presser member 50 includes a protruding part 60 which contacts the substrate 20 or the cover member 30. A contact width between the protruding part 60 and the substrate 20 or the cover member 30 is less than the distance d in the array direction of the plurality of light sources 10.
