Zusammenfassung:PROBLEM TO BE SOLVED: To provide an imaging lens that is bright and compact, and in particular has an excellently corrected spherical aberration.SOLUTION: An imaging lens is formed by disposing, in order from an object side to an image side, a first lens group G1 having a positive refractive power, an aperture stop S, and a second lens group G2 having a positive refractive power. The first lens group G1 is formed by disposing, in order from the object side to the image side, a positive lens L11, a positive lens L12, and a negative lens L13, and the second lens group G2 is formed by disposing, in order from the object side to the image side, a negative lens L21, a positive lens L22, and a positive lens L23. An interval Da on an optical axis between the positive lens L11 and the positive lens L12 in the first lens group, and a distance D1 on the optical axis from a lens surface closest to the object side of the first lens group to a lens surface closest to the image side thereof, satisfy a condition (1) 0.25
