Abstract
According to one embodiment, a self-ballasted lamp includes a light-emitting module, a base body, a first insulating member, a screw, a second insulating member, a cap and a lighting circuit. The light-emitting module has a light-emitting portion including semiconductor light-emitting elements mounted on a surface of a metallic substrate. The base body is made of metal and the light-emitting module is arranged on one end side of the base body. The first insulating member is interposed between the substrate of the light-emitting module and the base body. The substrate of the light-emitting module is fixed to the base body with the screws. The second insulating member is interposed between the screws and the substrate of the light-emitting module. The cap is provided at the other end side of the base body. The lighting circuit is housed inside the base body.
