Image Pickup Lens And Image Pickup Device

Abstract

The present invention provides a compact and high-performance image pickup lens having a fast F-number and capable of suppressing shading by using a curved projection surface. An image pickup lens 10 includes a first lens L1 having a positive refractive power, a second lens L2 having a negative refractive power, a third lens L3 having a positive or negative refractive power, a fourth lens L4 having a positive or negative refractive power, and a fifth lens L5 having a negative refractive power. With regard to the fifth lens L5 among these lenses, at least one surface is aspherical. The above-described image pickup lens 10 satisfies a conditional expression (1): −2.50<f5/f<−0.10 . . . (1) where f5 is a focal length of the fifth lens L5 and f is a focal length of the entire system of the image pickup lens 10.
