摘要： A composite lens of the present invention has a base lens and a resin lens placed on the base lens. The resin lens has, in an area outside an optically effective diameter, a first surface, a second surface that is adjacent to the first surface, and a third surface that is adjacent to the second surface in sequence from an optical axis to an outer circumference. The first surface has an inclined surface that becomes higher from the outer circumference toward the optical axis, and the inclined surface is connected to the second surface. The second surface has a plane that is substantially perpendicular to the optical axis, and the substantially perpendicular plane is connected to the first plane. The third surface has an inclined surface that becomes lower from an inner circumference toward the outer circumference.
