Abstract: An imaging lens consists of a front group having positive refractive power as a whole and a rear group in this order from an object side. The front group consists of three positive lenses, a negative lens with its concave surface facing an image side, a positive lens with its convex surface facing the object side, a negative lens with its concave surface facing the image side, a stop, a negative lens with its concave surface facing the object side and plural positive lenses in this order from the object side. The rear group has positive refractive power and consists of a positive lens and a negative lens in this order from the object side.

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