Abstract:
An imaging lens includes a first lens group; a second lens group; and a third lens group, arranged in this order from an object side. The first lens group includes a first lens having positive refractive power, a second lens, and a third lens with a space in between. The second lens group includes a fourth lens having negative refractive power and a fifth lens with a space in between. The third lens group includes a sixth lens having negative refractive power and a seventh lens with a space in between. A surface of the second lens on the object side has a positive curvature radius. A surface of each of the third lens and the sixth lens on the image plane side has a positive curvature radius. A surface of the fourth lens on the object side has a negative curvature radius. The first lens has a specific Abbe's number.

Claim (Index 8):
The imaging lens according to  claim 1 , wherein said fourth lens and said fifth lens have a composite focal length f 45  and said sixth lens and said seventh lens have a composite focal length f 67  so that the following conditional expression is satisfied:\n \u22123< f 45/ f 67<\u22120.8.
