Imaging lens assembly

An imaging lens assembly, comprising sequentially a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object side to an image side along an optical axis, and having a total effective focal length f,

• wherein the first lens has a positive refractive power, and an object-side surface of the first lens is a convex surface;
• the second lens has a negative refractive power;
• the third lens, the fourth lens, the fifth lens and the sixth lens each have a positive refractive power or a negative refractive power;
• and
• the total effective focal length f and an effective focal length of the fifth lens f5 satisfy:
• −2.0<f/f5<1.0,
• wherein the total effective focal length f and a center thickness CT6 of the sixth lens on the optical axis satisfy:
• f/CT6≥15.
