英文摘要	To improve an angular color difference and emit uniform illumination light. According to an embodiment, a light-emitting device in an embodiment includes a light-emitting module (15). The light-emitting module (15) includes a substrate (21), a plurality of light-emitting elements (45) made of semiconductor, and a plurality of sealing members (54). The light-emitting elements (45) are disposed on the substrate (21). The sealing members (54) contain, as a main component, translucent resin mixed with a phosphor. The sealing members (54) are heaped up from the bottom surfaces thereof bonded on the substrate (21) and are each formed to bury a singularity or a plurality of the light-emitting elements (45). A ratio (H/D) of a diameter D of the bottom surfaces to height H of the heaps of the sealing members (54) is set to 0.22 to 0.
