Abstract: There is provided an imaging lens and an imaging device with a wide angle of view capable of forming an image of an object near an optical axis with a high resolution while having a small size as a whole. The imaging lens is an imaging lens including a first lens G1 having a convex surface on an object side and having a negative refractive power, a second lens G2 having a concave surface on an object side, a third lens G3, a fourth lens G4, a fifth lens G5, and a sixth lens G6, which are sequentially arranged from the object side, and satisfies a predetermined condition. Further, an imaging device according to the present invention includes the imaging lens.

Abstract: An imaging lens and an imaging apparatus capable of acquiring a long-distance object image at high resolution and capable of acquiring a short-distance object image in a wide range while, as a whole, being configured small. In order to achieve the object, an imaging lens according to the present invention is an imaging lens consisting of n (n is a natural number equal to or larger than six) lenses including a first lens having negative refractive power and a second lens having positive refractive power in order from an object side and including an n-th lens having negative refractive power and an n−1-th lens having positive refractive power in order from an image side, the imaging lens satisfying a predetermined conditional expression.
