A lighting fixture capable of efficiently radiating heat of a lamp device may be configured to be attached to a socket device. In some examples, by attaching the lamp device to the socket device, a cap portion of the lamp device is brought into contact with a fixture body, and pressed against and brought into close contact with the fixture body by an elastic body. Heat generated by lighting of LEDs of the lamp device is conducted from the cap portion to the fixture body and efficiently radiated.

The invention provides a self-ballasted lamp having high heat radiation performance, which is lightweight and inexpensive. A substrate having LED elements mounted is provided at one edge side of the radiator, and a cap is provided at the other edge side the radiator. A lighting circuit is accommodated between the radiator and the cap. The radiator includes a cylindrical cover member and an annular radiation member fitted to the outer circumferential part of the cover member and is composed by combining the cover member and the radiation member together. The cover member and the radiation member are made of metal and are formed by press-working.
