A cooling appliance is proposed. A casing (100, 200) may include a cavity (S) therein, and a heat source module may be arranged inside the casing (100, 200). Furthermore, a camera module (730) may be arranged at a rear surface of the casing (100, 200) and capture the inside space of the cavity (S). Accordingly, in the casing (100, 200), heat sources and the camera module (730) may be arranged without interference therebetween, and the camera module (730) can secure a wide view angle at a rear portion of the casing (100, 200).
