Abstract: An imaging lens substantially consists of, in order from an object side, five lenses of a first lens that has a positive refractive power and is convex toward the object side, a second lens that has a negative refractive power, a third lens, a fourth lens that has a positive refractive power, and a fifth lens that has a negative refractive power and has an object side surface and an image side surface which have aspheric shapes. Further, the imaging lens satisfies predetermined conditional expressions.
