| titleOfInvention | Light emitting device and manufacturing method thereof |
| abstract | A light-emitting device that easily draws heat from a fluorescent material and has less unevenness in emission chromaticity distribution is provided. In addition, a method for manufacturing such a light-emitting device with good productivity is provided. A light-emitting device (100) according to an embodiment includes a light-emitting element (10) and a first region disposed above the light-emitting element (10) and positioned immediately above the upper surface of the light-emitting element (10). A translucent member (20) including a second region (20b) positioned laterally from the first region (20a), a side surface of the light emitting element (10), and a second translucent member. A light guide member (30) that covers the lower surface of the region (20b), and a light reflective member (40) that covers the outer surface of the light guide member (30). It contains a substance (25) and a light scattering material (28) that is not a fluorescent substance. The concentration of the fluorescent substance (25) is higher in the first area (20a) than in the second area (20b), and light scattering The concentration of the material (28) is higher in the second region (20b) than in the first region (20a).
