Abstract
In one embodiment, a lamp includes a thermal conductive hollow base body having a concave container portion, an opening portion formed at one end portion so as to communicate with the container portion and a substrate support portion formed at a peripheral portion of the opening portion. A substrate is formed of one of a thermal conductive metal plate and a thermal conductive insulating plate and including a semiconductor lighting element mounted on one surface. A peripheral portion of the other surface of the substrate is fixed to the substrate support portion so as to cover the opening portion in a thermally conductive state therebetween. A power supply device is accommodated in the container portion of the base body to light on the semiconductor lighting element. A base is provided at the other end portion side of the base body and electrically connected with the power supply device.
