Abstract

An imaging lens substantially consists of five lenses of an aspheric first lens having a convex surface facing an object side and positive refractive power, an aspheric second lens having a concave surface facing the object side and negative refractive power, an aspheric third lens having a meniscus shape in which its object-side surface is convex toward the object side, and positive refractive power, an aspheric fourth lens having negative refractive power and a fifth lens having a convex surface facing the object side and positive refractive power, which are in this order from the object side. Further, the imaging lens satisfies predetermined conditional formulas.
