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.
