An imaging lens substantially includes five lenses, constituted by: a first lens having a positive refractive power; a second lens having a negative refractive power; a third lens having a positive refractive power and a convex surface that faces an object side; a fourth lens having a negative refractive power and a meniscus shape with a concave surface that faces the object side; and a fifth lens having a positive refractive power, a meniscus shape with a convex surface that faces the object side, and at least one inflection point on the surface thereof toward an image side.
