An imaging lens including two lenses that are small and have good optical characteristics is provided. In order from the object side to the image surface side, a stop S1, a meniscus first lens L1 having a positive power with a convex surface facing the object side, and a negative power with a convex surface facing the image surface side When the focal length of the whole imaging lens is f, the focal length of the first lens is f1, and the focal length of the second lens is f2, the following conditional expression (1) And (2) is satisfied. −1.00 <f / f2 <−0.04 (1) −0.70 <f1 / f2 <−0.05 (2) [Selection] Figure 1 |
