Abstract: An imaging lens is constituted of five lenses, including, in order from the object side to the image side: a first lens having a positive refractive power, which is of a meniscus shape having a convex surface toward the object side; a second lens having a negative refractive power and a concave surface toward the image side; a third lens having a positive refractive power, which is of a meniscus shape having a convex surface toward the object side; a fourth lens having a negative refractive power; and a fifth lens having a negative refractive power and at least one inflection point on the surface thereof toward the image side. Predetermined conditional formulae are satisfied.
