Abstract: An imaging lens assembly module includes an imaging lens element set, a lens carrier and a light blocking structure. The imaging lens element set has an optical axis. At least one lens element of the lens elements is disposed in the lens carrier. The light blocking structure includes a light blocking opening. The optical axis passes through the light blocking opening, and the light blocking opening includes at least two arc portions and a shrinking portion. Each of the arc portions has a first curvature radius for defining a maximum diameter of the light blocking opening. The shrinking portion is connected to the arc portions for forming the light blocking opening into a non-circular shape. The shrinking portion includes at least one protruding arc which extends and shrinks gradually from the shrinking portion to the optical axis, and the protruding arc has a second curvature radius.
