To provide an imaging lens system, a camera module, an onboard system and a mobile entity which are reduced in size, and with which it is possible to achieve a high resolution.SOLUTION: The imaging lens system comprises, in order from the object side to the image side: a first lens L1 having negative power, with the image-side surface having its concavity directed to the image side; a second lens L2 having negative power, with the image-side surface having its concavity directed to the image side; a third lens L3 having positive power, with the object-side surface having its convexity directed to the object side; a diaphragm STOP; a fourth lens L4 having positive power, with the image-side surface having its convexity directed to the image side; and a fifth lens L5 and a sixth lens L6 constituting a cemented lens, one of which has negative power and the other has positive power. A point on the optical axis of the object-side surface of the third lens L3 is located closer to the object side than the position on the optical axis of a peripheral end that is the boundary of the optical surface and edge surface of the image-side surface of the second lens L2.SELECTED DRAWING: Figure 2
