Abstract: Provided are an imaging lens, which is a wide-angle imaging lens and is capable of satisfactorily correcting various aberrations, and an imaging apparatus which includes this imaging lens. The imaging lens consists of, in order from an object side: a first lens L1 that has a negative refractive power; a second lens L2 that has a negative refractive power; a third lens L3 that has a positive refractive power; a fourth lens L4 that has a negative refractive power; a fifth lens L5 that has a positive refractive power; a sixth lens L6 that has a positive refractive power; and a seventh lens L7 that has a negative refractive power. The following conditional expression (1) is satisfied. −2

Abstract: An imaging lens substantially consists of negative first lens, positive second lens, negative third lens, positive fourth lens, positive fifth lens, and negative sixth lens in this order from an object side. At least one of second lens through sixth lens satisfies the following conditional expression (1), and the imaging lens, as a whole, satisfies the following conditional expression (2): (1/τi)×(f/fi)
