Patent ID: 7948690

Claim:
A composite lens, comprising: a base lens; and a resin lens, provided on the base lens, and having, in an area outside an optically effective diameter and on a surface of the resin lens that is opposite to a surface of the resin lens at a side of the base lens, a first surface and a second surface that is adjacent to the first surface and a third surface that is adjacent to the second surface in a sequence from an optical axis of the base lens toward an outer circumference of the resin lens, the resin lens being joined to the base lens without forming a closed space between the base lens and the resin lens; wherein the first surface has an inclined surface that becomes higher from the outer circumference toward the optical axis and that is connected to the second surface; the second surface has a plane that is substantially perpendicular to the optical axis and that is connected to the inclined surface; and the third surface has an inclined surface that becomes lower from the inner circumference toward the outer circumference.
