| titleOfInvention | Imaging lens, imaging device, and portable terminal |
| abstract | There is provided a small imaging lens having a five-lens structure that has sufficient brightness of about F2 and various aberrations are favorably corrected. An imaging lens includes, in order from the object side, a first lens having a positive refractive power and having a convex surface facing the object side, and a second lens having a negative refractive power and having a concave surface facing the image side. A lens L2, a third lens L3 having positive or negative refractive power, a fourth lens L4 having positive refractive power and having a convex surface facing the image side, and a concave surface having negative refractive power and having a negative refractive power on the image side And the image side surface of the fifth lens L5 has an aspherical shape and has an inflection point at a position other than the intersection with the optical axis.
