1. An imaging lens assembly driving module, comprising:
a lens carrier defining an optical axis;
a first molded structure disposed correspondingly to the lens carrier and comprising a first light blocking structure;
a second molded structure coupled to the first molded structure for forming an inner space, the lens carrier accommodated in the inner space, and the second molded structure comprising a second light blocking structure;
a driving mechanism for driving the lens carrier to move along the optical axis; and
a mechanical member for connecting the lens carrier and the first molded structure;
wherein the first molded structure is coupled to the second molded structure so that the first light blocking structure and the second light blocking structure are disposed correspondingly to each other for forming a light passing hole, and the optical axis passes through the light passing hole;
wherein a cross section of the light passing hole passing through the optical axis comprises:
a valley point being a farthest point away from the optical axis in the cross section;
a first crest point being a closest point to the optical axis in the cross section; and
a second crest point being a closest point to the optical axis in another side relative to the first crest point based on a perpendicular line from the valley point to the optical axis;
wherein a distance between the valley point and the optical axis is D, a distance between the first crest point and the optical axis is d1, a distance between the second crest point and the optical axis is d2, and the following conditions are satisfied:
0.1<d1/D<0.95; and
0.1<d2/D<0.95.
