A compact low-profile imaging lens which offers a wide field of view and corrects aberrations properly. It includes: a first positive (refractive power) lens having a convex object-side surface as a first optical element; a second negative meniscus lens having a concave image-side surface as a second optical element; a third lens having at least one aspheric surface as a third optical element; a fourth lens having at least one aspheric surface as a fourth optical element; a fifth lens having at least one aspheric surface as a fifth optical element; and a sixth double-sided aspheric lens having a concave image-side surface as a sixth optical element. The aspheric image-side surface of the sixth lens has pole-change points off an optical axis. As a seventh optical element, one double-sided aspheric aberration correction optical element with virtually no refractive power is located between the first lens and an image plane.
