Zusammenfassung:This imaging lens is constituted from: in order from an object side to an image surface side on which an imaging element is disposed, a front-group lens system having positive refractive power; and a rear-group lens system having, furthest toward the image surface side, a lens surface which is concave on the image surface side in the vicinity of the optical axis and convex on the image surface side in a peripheral part; the imaging lens satisfying the conditional expressions below. (1): 1.0 < Gun2R2(sag6 - sag10)/(TTL/2Y) < 2.8. (2): 5.0(%) < ODMAX < 20.0(%).
