An imaging lens includes a first lens group having a negative refractive power, an aperture stop, and a second lens group having a positive refractive power. The first lens group, the aperture stop, and the second lens group are sequentially disposed in a direction from an object side to an image side. The first lens group includes a negative first lens and a negative second lens. The second lens group includes a positive third lens, a positive fourth lens, a negative fifth lens, and a positive sixth lens. Conditional formula (1) below is satisfied:0.16DL3/TL0.32 (1)whereDL3 is a center thickness of the third lens, andTL is distance between an object-side surface of the first lens and an image-side surface of the sixth lens along the optical axis.展开▼
