<p>[Problem] To provide: an imaging lens that has a small f-number, and achieves a reduction of the overall length and high resolution, while maintaining an image size that enables a desired resolution to be achieved; and an imaging device provided with the imaging lens. [Solution] This imaging lens essentially comprises five lenses consisting of, in order from the object side, a meniscus first lens (L1) having a positive refractive power, and a convex face facing the object side; a biconcave second lens (L2); a biconcave third lens (L3); a meniscus fourth lens (L4) having a convex face facing the image side; and a biconcave fifth lens (L5) having at least one inflection point on the image-side face. The imaging lens satisfies prescribed conditional expression (2).</p> |
