| titleOfInvention | Imaging lens |
| abstract | The imaging lens includes, in order from the object side, a positive first lens, a negative second lens, a positive third lens, and a negative fourth lens, and the object side surface of the fourth lens is concave or flat. The image side surface is concave, and conditional expression: 0.74 ≦ f1 / f ≦ 2, 0.22 ≦ (r2A + r2B) / (r2A−r2B) ≦ 1.0 (f1: focal length of the first lens, f: The focal length of the entire imaging lens system, r2A: the radius of curvature of the object side surface of the second lens, and r2B: the radius of curvature of the image side surface of the second lens) are satisfied, and the subject image is formed on the imaging surface of the imaging device. |
