<p>The purpose of the present invention is to provide an image pickup lens capable of suppressing ghost light and forming a high-quality image although having a relatively large number of lenses and a low height, and an image pickup device using the same. An image pickup lens comprising a positive first lens (L1) with the convex surface thereof facing the object side to a fifth lens (L5) which are disposed in order from the object side, wherein an aperture stop (S) is located closer to the object side than the third lens (L3), antireflection films are respectively formed on an object-side optical surface and an image-side optical surface of at least the first lens (L1), and the image pickup lens being used for forming a subject image on an image pickup surface of a solid-state image pickup element. The antireflection film is configured from a plurality of layers formed by alternately stacking high refractive index layers and low refractive index layers, and the thickness of the antireflection film on the object-side optical surface is made thicker than the thickness of the antireflection film on the image-side surface on the optical axis of the first lens (L1).</p> |
