Abstract: An imaging lens module includes an imaging lens unit, an optical folding component and a sensing magnet group. The imaging lens unit has an optical axis. The optical folding component is configured to fold an incident optical path into the imaging lens unit to coincide with the optical axis. The sensing magnet group includes two sensing magnets that are sequentially disposed on the imaging lens unit along a direction in parallel with the optical axis. The sensing magnets are located at the same side with respect to a reference plane that passes through the optical axis and has a normal direction perpendicular to the optical axis. When the sensing magnets are observed from the direction in parallel with the optical axis, images of the sensing magnets are at least partially overlapped. Two adjacent magnetic poles of the sensing magnets are like poles between which there is a repulsive force.

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.
