An exterior mirror for a vehicle includes a mirror housing that houses a mirror, a chassis that is put on the mirror housing to form a hollow space between the chassis and the mirror housing, the chassis having an opening former at a portion, and a lamp that is arranged in the hollow space. The lamp includes a light source that emits light, and a reflector that reflects the light toward the opening. The light source is arranged in such a manner that the light from the light source does not illuminate the opening directly.
