A lighting apparatus includes: a light source; a sealed housing accommodating the light source therein; and an aiming screw rotatably supported in a through-hole which extends through the housing. Therefore, an optical axis of light emitted from the light source can be adjusted by rotating the aiming screw. A breathing passage communicating inside and outside of the housing with each other is provided inside the aiming screw, so that it is unnecessary to separately provide a breathing passage, thereby enabling decrease in the number of parts, and simplification of the structure. Accordingly, breathing of the housing of the lighting apparatus is achieved using a simple and compact structure.
