An imaging lens, substantially consisting of five lenses, composed of a positive first lens with a convex surface on the object side, a negative second lens with a concave surface on the object side, a third lens having a negative meniscus shape with a convex surface on the object side, a fourth lens having a positive meniscus shape with a concave surface on the object side, and a negative fifth lens with a concave surface on the image side, the image side surface having an aspherical shape with at least one inflection point located inward in a radial direction from the intersection between the image side surface and a principal ray of the maximum angle of view toward the optical axis, disposed in order from the object side, and satisfies given conditional expressions.
