The present invention addresses the problem of reducing the weight and cost by including a resin lens, and suppressing variations in the angle of view associated with changes in the ambient temperature. [Solution] Provided is an imaging lens configured from n lenses including, in order from the object side, a first lens (L1) having a concave image side, a second lens (L2) having a concave object side, and an n-th lens disposed closest to the image side, where 5 < = n < = 10, where n is greater than or equal to 1 and less than or equal to 10, where n is greater than or equal to 1 and less than or equal to 2, where n is greater than or equal to 1 and less than or equal to 2, where n is greater than or equal to 1 and less than or equal to 2, and where n is greater than or equal to 1 and less than or equal to 1, and n is greater than or equal to 1 and less than or equal to 2, are disposed in this order from the object side. The second group includes a lens Gp having a refractive index N corresponding to the d-lin
