Abstract: A camera module includes a fixed base, a carrier, an elastic element, an imaging lens, a coil, a magnetic element, a connection wire and a light-blocking coating. The carrier is disposed opposite to the fixed base and has a bobbin. The elastic element is connected to the fixed base and the carrier so as to provide freedom of movement of the carrier with respect to the fixed base. The imaging lens is disposed on the carrier and has an optical axis. The coil is disposed on the carrier. The magnetic element is disposed corresponding to the coil so as to provide a driving force for moving the carrier. The connection wire is disposed on the bobbin and electrically connected to the elastic element and the coil, and the connection wire has at least part facing towards the optical axis where the light-blocking coating is disposed.

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.
