A light-emitting apparatus has a substrate (72) having a generally disc shape, a light-emitting part (76) having a plurality of LED chips (73) mounted on one main surface of the substrate (72), the plurality of LED chips (73) being sealed with a resin (74), and a heat-sink attachment part having a heat-sink attachment male thread (80) formed on a side surface of the substrate (72). When the attachment area of the substrate (72) to the heat sink is kept the same, the light-emitting part (76) may be enlarged, and when the light-emitting unit (76) is kept the same, the attachment area of the substrate (72) may be reduced. |
