ABSTRACT:
An imaging lens unit which achieves a lower profile without adversely affecting the optical performance. The imaging lens unit includes a first lens, an aperture stop, a second lens, and a third lens arranged sequentially along the optical axis from the object side to the image side. The first lens includes a first surface located on the object side and being convex toward the object side and a second surface located on the image side and being concave toward the image side near the optical axis and convex toward the image side as the rim of the first lens becomes closer.
