Abstract
An imaging lens substantially includes six lenses, constituted by: a first lens having a positive refractive power and a convex surface that faces an object side; a second lens having a negative refractive power; a third lens having a positive refractive power; a fourth lens having a positive refractive power; a fifth lens having a negative refractive power and a concave surface that faces the object side; and an aspherical sixth lens having a negative refractive power, the surface of which is concave toward an image side in the vicinity of an optical axis and convex toward the image side at the peripheral portion thereof. The imaging lens satisfies a predetermined conditional formula.
