Abstract
There is provided an imaging lens with high resolution which satisfies in well balance the low-profileness and the low F-number and properly corrects aberrations. An imaging lens comprises a first lens having positive refractive power, a second lens having the positive refractive power, a third lens, a fourth lens, a fifth lens being a double-sided aspheric lens, and a sixth lens being double-sided aspheric lens and having a concave surface facing the image side near the optical axis, wherein the image-side surface of the sixth lens is an aspheric surface changing to the convex surface at a peripheral area.
