Abstract: A camera module includes a unitary element, an optical image lens assembly, a fixed member and a driving member. The unitary element has an object-side opening. The optical image lens assembly is disposed in a containing space and has an optical axis. The fixed member is for accommodating the unitary element and includes a base and a cover, and the cover has a through hole and is connected with the base. The driving member is for driving the unitary element to move relative to the fixed member. The unitary element includes a reverse inclined structure including at least two annular concave structures. The at least two annular concave structures are arranged in order from the object-side opening to an image side, wherein a sectional surface of each of the annular concave structures passing through the optical axis includes a valley point and two concave ends.

Abstract: A camera module includes a housing, a unitary element, an optical lens assembly, an image-side light blocking assembly and a driving device. The unitary element is one-piece formed from a lens carrier and a lens barrel and movably disposed in the housing. The optical lens assembly is disposed in the unitary element. The image-side light blocking assembly includes at least one light blocking sheet, and the image-side light blocking assembly does not contact the optical lens assembly. The driving device is disposed between the housing and the unitary element. The driving device drives the unitary element, the optical lens assembly and the image-side light blocking assembly to move in an optical axis direction parallel to an optical axis of the optical lens assembly by electromagnetic force. A minimal inner opening of the unitary element is located between the optical lens assembly and the image-side light blocking assembly.
