Abstract:
A self-ballasted lamp includes: a base body; a light-emitting module and a globe which are provided at one end side of the base body; a cap provided at the other end side of the base body; and a lighting circuit housed between the base body and the cap. The light-emitting module has light-emitting portions each using a semiconductor light-emitting element, and a support portion projected at one end side of the base body, and the light-emitting portions are disposed at least on a circumferential surface of the support portion. A light-transmissive member is interposed between the light-emitting module and an inner face of the globe.
