摘要：
An imaging lens (LN) includes at least three lens blocks (BK), and an aperture stop (ape). The lens block (BK) includes parallel flat lens substrates (LS) formed of different materials, and a lens (L). In the imaging lens (LN), the object side lens surface of a first lens (L1) included in a first lens block (BK1) is a surface protruding to the object side, the object side lens surface of a third lens (L3) included in a second lens block (BK2) is a surface recessed from the object side, and at least the object side lens surface of a fifth lens (L5) or the object side lens surface of a sixth lens (L6) included in a third lens block (BK3) is aspherical.
