Abstract
In an apparatus for watching around a vehicle, an internal reflection preventive film for preventing stray light from undergoing total reflection in a prism is formed outside an effective area with respect to an imaging lens disposed to the rear side B of the prism. Thus, the quantity of stray light is reduced by preventing the total reflection.
