An imaging lens is essentially constituted by seven lenses, including: a positive first lens having a convex surface toward the object side; a second lens, of which at least one surface is of an aspherical shape; a third lens, of which at least one surface is of an aspherical shape; a fourth lens, of which at least one surface is of an aspherical shape; a positive fifth lens of a meniscus shape with a convex surface toward the image side; a sixth lens, of which at least one surface is of an aspherical shape; and a negative seventh lens having a concave surface toward the image side, provided in this order from the object side. The imaging lens satisfies a predetermined conditional formula.
