A lighting apparatus 100 includes a light source module 1, a heat sink 3 holding the light source module 1 and a light-permeable cover 5 mounted to the heat sink 3 and covering the light source module 1. The cover 5 is adhered to the heat sink 3 by an adhesive agent 55 applied with a gap formed on at least one part between the cover 5 and the heat sink 3. The inside and outside of the lighting apparatus 100 can be communicated to each other due to the gap. Since the inside and outside of the lighting apparatus 100 are communicated to each other, the problems of temperature difference and pressure difference between inside and outside of the lighting apparatus 100 can be suppressed so that the occurrence of defects because of condensation and the like can be prevented. |
