Abstract:
An imaging lens includes a first lens group; a second lens group; and a third lens group, arranged from an object side to an image plane side. The first lens group includes a positive first lens, a negative second lens, and a third lens. The second lens group includes a fourth lens and a fifth lens. The third lens group includes a sixth lens and a seventh lens. The first to seventh lenses are arranged on an optical axis with a space in between respectively. The seventh lens is formed in a shape so that a surface thereof on the object side and a surface thereof on the image plane side have positive curvature radii. The surface of the seventh lens on the image plane side is formed in an aspheric shape having at least one inflexion point. The first and third lenses have specific Abbe's numbers.

Claim (Index 4):
The imaging lens according to  claim 1 , wherein said seventh lens has a focal length f7 so that the following conditional expression is satisfied:\n \u22124.0< f 7/ f<\u2212 0.8 where f is a focal length of a whole lens system.
