| abstract | Provided is an imaging lens that is small and includes three lenses having good optical characteristics. In order from an object, an aperture S1, a meniscus positive first lens L1 having a convex surface facing the object side, a meniscus negative power second lens L2 having a convex surface facing the image side, and toward the object side. An imaging lens LA, wherein a meniscus positive third lens L3 having a convex surface is disposed and satisfies the following conditional expressions (1) to (3). 0.20 <R1 / R2 <0.60 (1) −0.85 <f1 / f2 <−0.20 (2) 0.70 <d1 / d2 <0.95 (3) [Selection] Figure 1 |
