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.
