PROBLEM TO BE SOLVED: To provide an advanced and compact imaging lens that is small, uses fewer lenses, has high performance and adopts an appropriate structural shape and a plastic material. SOLUTION: The imaging lens includes: a first lens that is a meniscus having an object-oriented convex and a positive refractive power; a second lens that is a meniscus having a paraxially object-oriented concave and a negative refractive power; and a third lens that is a meniscus having a paraxially object-oriented convex and a positive refractive power.
