Abstract
An imaging lens is constituted by, in order from the object side to the image side: a negative first lens having a concave surface toward the image side; a positive second lens having a convex surface toward the image side; a negative third lens having a concave surface toward the image side; a positive biconvex fourth lens; a positive biconvex fifth lens; and a negative sixth lens having a concave surface toward the object side. Conditional Formula (1) related to the radius of curvature R3 of the surface of the second lens toward the object side and the focal length f of the entire lens system is satisfied:3/<0  (1).
