An imaging lens is constituted by, in order from the object side to the image side: a front group having a negative refractive power; and a rear group having a positive refractive power. The front group is constituted by two negative lenses. The rear group includes a cemented lens formed by cementing a negative lens and a positive lens having a smaller Abbe's number with respect to the d line (wavelength: 587.6 nm) than the negative lens, provided in this order from the object side to the image side, together.
