摘要：
An imaging lens includes first to third lenses G1 to G3 arranged in order from a object side. The first lens has a biconvex shape in a vicinity of an optical axis Z1. The second lens has a concave surface facing a object side. The second lens has a negative refractive power. The third lens has a positive or negative refractive power and has a meniscus shape containing, in a vicinity of the optical axis, a convex surface facing the object side. The following conditional expression is satisfied: 0.7
