A lighting device according to an embodiment includes a light source module, a thermal radiation member, and a fixing member. The light source module is a module mounted with a light-emitting element such as an LED (Light Emitting Diode) on the inside and including the light-emitting element as a light source. In the thermal radiation member, the light source module is set. The thermal radiation member radiates heat generated from the light source module. A fixing member is screwed on a sidewall of the thermal radiation member in a state in which the fixing member surrounds the light source module and the thermal radiation member.
