1. An imaging lens assembly module, comprising:
an imaging lens element set comprising a plurality of lens elements, and having an optical axis;
a lens carrier, wherein at least one lens element of the lens elements is disposed in the lens carrier;
a light blocking structure located on the lens carrier, and comprising:
a light blocking opening, the optical axis passing through the light blocking opening, and the light blocking opening comprising:
at least two arc portions, wherein each of the at least two arc portions has a first curvature radius, and the first curvature radius is for defining a maximum diameter of the light blocking opening; and
a shrinking portion connected to the at least two arc portions, wherein the shrinking portion comprises at least one protruding arc extending and shrinking gradually from the shrinking portion to the optical axis, and the at least one protruding arc has a second curvature radius; and
a driving device for driving the at least one lens element of the lens elements and the light blocking structure to move simultaneously along the optical axis;
wherein the maximum diameter of the light blocking opening is D, the second curvature radius of the at least one protruding arc is R, and the following condition is satisfied:
