Abstract
An imaging lens is constituted by six 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 convex surface toward the object side; a third lens having a positive refractive power; a fourth lens having a positive refractive power; a fifth lens having a positive refractive power and a convex surface toward the object side; and a sixth lens having a negative refractive power, provided in this order from the object side. The imaging lens satisfies a predetermined conditional formula.
