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