Image capturing module having a built-in dustproof structure

An image capturing module having a built-in dustproof structure, comprising:

• an image sensing unit including a substrate and an image sensing chip disposed on the substrate and electrically connected to the substrate;
• a housing frame disposed on the substrate to surround the image sensing chip;
• an actuator structure disposed on the housing frame and located above the image sensing chip, wherein the actuator structure includes a lens holder disposed on the housing frame and a movable lens assembly disposed inside the lens holder, the lens holder includes a surrounding movable member movably disposed therein, the movable lens assembly is fixed inside the surrounding movable member through at least two tiny bonding glue, and the movable lens assembly is movably disposed inside the lens holder through the surrounding movable member;
• wherein the surrounding movable member of the lens holder has a first surrounding structure disposed on the inner surrounding surface thereof, and the movable lens assembly has a second surrounding structure disposed on the outer perimeter surface thereof and located above the first surrounding structure, and the first surrounding structure of the surrounding movable member and the second surrounding structure of the movable lens assembly are mated with each other to form the built-in dustproof structure.
