Abstract

An imaging lens is substantially constituted by five lenses, including: a first lens having a positive refractive power and 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 negative refractive power and a concave surface toward the object side; a fourth lens having a positive refractive power and is of a meniscus shape with a concave surface toward the object side; and a fifth lens having a negative refractive power and is of a meniscus shape having a convex surface toward the image side, provided in this order from the object side. The imaging lens satisfies a predetermined conditional formula.
