Claim:
An imaging lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface; a second lens element with refractive power; a third lens element with positive refractive power; a fourth lens element with negative refractive power having a concave object-side surface and a convex image-side surface; to a fifth lens element with positive refractive power having a convex object-side surface, wherein the object-side surface and an image-side surface of the fifth lens element are aspheric; and a sixth lens element with refractive power having a convex object-side surface and a concave image-side surface, wherein the object-side surface and the image-side surface of the sixth lens element are aspheric, and the sixth lens element has at least one inflection point on at least one of the object-side surface and the image-side surface thereof; wherein the imaging lens assembly has a total of six lens elements with refractive power, a curvature radius of the object-side surface of the fifth lens element is R9, a curvature radius of the image-side surface of the fifth lens element is R10, an axial distance between the fifth lens element and the sixth lens element is T56, a central thickness of the fifth lens element is CT5, a central thickness of the sixth lens element is CT6, and the following relationships are satisfied: −3.0<( R 9 +R 10)/( R 9 −R 10)<0.30; and 0<( T 56 +CT 6)/ CT 5<3.0.
