Abstract
Provided are an imaging lens that has a small amount of focus shift caused by temperature fluctuation and an imaging apparatus that has this imaging lens. The imaging lens consists of, in order from an object side: a first lens that is convex toward the object side and has a negative refractive power; a second lens that has a negative refractive power; a third lens that has a positive refractive power; a fourth lens that has a positive refractive power; a fifth lens that has a positive refractive power; and a sixth lens that has a negative refractive power. The imaging lens satisfies the following conditional expressions (1) to (4).−0.89<12<−0.53   (1)−0.19<1<−0.1   (2)−0.70<2<−0.45   (3)2.4<1/2<5.7   (4)
