Abstract
A surface mount type light-emitting unit composed of a light-emitting device, a first lead connected electrically with a first electrode of the light-emitting device, a second lead connected electrically with a second electrode of the light-emitting device, and a clear insulator for sealing the light-emitting device, a connecting section of the first electrode of the light-emitting device and the first lead, and a connecting section of the second electrode of the light-emitting device and the second lead wherein connecting terminal sections of the first and second leads for connecting them with external devices, respectively, are placed on a surface of the insulator, comprises an end of the first lead being molded into a cup-shaped portion having a flat bottom; the light-emitting device being bonded to the bottom inside a reflecting section corresponding to the molded cup-shaped portion of the first lead; and a surface opposed to that of the reflecting section on which the light-emitting device has been bonded being exposed to the surface of the insulator.
