An imaging lens consists of five lenses, including: a first lens having a positive refractive power and a meniscus shape with a convex surface toward the object side, a second lens having a biconcave shape with the surface having the radius of curvature with the smaller absolute value toward the image side, a third lens having a meniscus shape with a convex surface toward the object side, a fourth lens having a negative refractive power and a meniscus shape with a convex surface toward the image side, and a fifth lens having a negative refractive power and a meniscus shape with a concave surface toward the image side, the image-side surface thereof having at least one inflection point, disposed in this order from the object side.
