IMAGE PICKUP LENS AND IMAGE PICKUP DEVICE

This aims at providing an imaging lens having small size, low cost, high environment-resistance, a wide angle of view, a small F-number and high performance, and an imaging apparatus including the imaging lens. An imaging lens (1) consists of negative first lens (L1) having a concave image-side surface, positive second lens (L2), negative third lens (L3), positive fourth lens (L4), positive fifth lens (L5) having a convex image-side surface, and negative sixth lens (L6), which are in this order from an object side. In the imaging lens (1), all of the lenses constituting the lens system are single lenses, which are not cemented lenses, and a stop is arranged closer to the object side than an image-side surface of the fourth lens (L4) is arranged. When a refractive index of a material of the third lens (L3) for d-line is Nd3, the following formula (1) is satisfied: Nd ¢ 3 < 1.75
