A lamp capable of suppressing an increase in a temperature of semiconductor light-emitting devices such as LED is provided. The lamp includes an LED module (11) which is a light source, a radiator (14) thermally coupled to the light source, a lighting circuit (13) for turning the lighting source on and is housed in the radiator (14), and a base (12) for supplying power to the lighting circuit (13), and the radiator (14) includes a heat sink (15) covering the lighting circuit (13) and a light source attachment (16) to which the light source is placed. Furthermore, a convex (16b) of an end portion of the light source attachment (16) is fit into a recess (15c) of the heat sink (15).
