An imaging device of the disclosure includes an imaging lens; an imaging element that converts an optical image formed on an image forming surface by the imaging lens, into an electric signal; and a computing device that corrects distortion aberration of an image picked up by the imaging element. The imaging lens includes, in order from object side, a front-group lens system having positive refractive power, and a rear-group lens system having negative refractive power, a lens surface on a closest side to the image of the rear-group lens system being concave on an image side near an optical axis and convex on the image side around a periphery, and the following conditional expression is satisfied:5(%)&#x3c;&#x3c;20(%)&#x2003;&#x2003;(1)

Imaging device and imaging lens

An imaging unit of the disclosure includes an imaging lens including a first lens group and a second lens group that are disposed in order from object side toward image side, and an imaging device that converts an optical image formed by the imaging lens into an electric signal. The second lens group and the imaging device are rotationally moved integrally to allow the second lens group and the imaging device to be tilted with respect to an optical axis of the first lens group.

An imaging lens according to the disclosure includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. The first lens includes a meniscus lens that has a convex surface facing object side and has positive refractive power near an optical axis. The second lens has a convex surface facing the object side and has negative refractive power near the optical axis. The third lens has positive refractive power near the optical axis. The fifth lens has positive refractive power near the optical axis. The sixth lens has negative refractive power near the optical axis and has an aspheric surface on the image plane side. The aspheric surface has an inflection point. The first lens, the second lens, the third lens, the fourth lens, the fifth lens, and the sixth lens are disposed in order from the object side toward the image plane side. The imaging lens satisfies the following conditional expressions.5&#x3c;1&#x2003;&#x2003;(1)&#x2212;0.9&#x3c;(51+52)/(51&#x2212;52)&#x3c;4&#x2003;&#x2003;(2)2/6&#x3e;1&#x2003;&#x2003;(3)
