    Abstract: An imaging lens, an imaging apparatus having the imaging lens, and a personal communication device having the imaging apparatus are provided to correct various aberrations satisfactorily, and to cope with an imaging device of a great number of pixels. An imaging lens(10) images light from a subject on an imaging device, and includes an aperture stop(S), a first lens(L1), a second lens(L2), a third lens(L3), and a fourth lens(L4) in order from an object. The first lens(L1) has a plus refractive force. The second lens(L2) has a minus refractive force, and a concave surface thereof faces an image side. The third lens(L3) has a plus refractive force. The fourth lens(L4) has a minus refractive force, and a concave surface thereof faces the image side. When the radius of curvature of the image side surface of the second lens(L2) is r4, and the focal distance of the imaging lens(10) is f, a formula: 0.2
