Abstract
An illumination device consists of a light emitting element, a casing for supporting the light emitting element, and a colored cap which covers the light emitting element. The cap has a flat top surface so that the device can be held by suction stably at the top surface by means of a suction nozzle that is used commonly for other electronic parts and can be carried and mounted on a circuit board by the automatic part mounting equipment. The cap also has the formation of a curving surface section between the flat top surface and cylindrical section so that an increased amount of light is transmitted in the up-oblique direction through the curving surface section, thereby compensating the degraded light distribution caused by the formation of the flat top surface.
