The lighting apparatus according to the present invention includes a thermal source such as a light source or a power supply unit and a heat releasing portion for releasing heat from the thermal source, and further includes the first heat radiation film formed by applying a coating material containing a heat radiating material on the surface of the heat releasing portion and curing the material. Since the first heat radiation film is formed by curing the material containing a heat radiating material, heat emittance by infrared is improved compared to the case with a heat radiation film formed by anode oxide coating (alumite treatment), thereby enhancing the heat releasing performance while maintaining the heat releasing performance by heat radiation for a long period of time because of the high resistance to damages.
