An imaging lens is constituted by, in order from the object side to the image side: a negative front group; a stop; and a positive rear group. The front group is constituted by, in order from the object side to the image side, a front group negative lens group, constituted by at least two negative lenses, and a front group positive lens group including one negative lens and one positive lens, in which a positive lens is provided most toward the object side. The rear group includes one negative lens and one positive lens. Conditional Formula (1) below is satisfied: Nan+0.01·&ngr;an<2.15   (1) wherein Nan and &ngr;an respectively are the refractive index with respect to the d line and the Abbe's number with respect to the d line of the negative lens provided most toward the image side within the front group positive lens group. |
