Abstract: An optical member driving mechanism for driving an optical member having an optical axis is provided, including a fixed portion, a movable portion, a first elastic member, and a driving assembly. The movable portion is configured to hold the optical member, and is movably connected the fixed portion via the first elastic member. The driving assembly drives the movable portion to move along the optical axis within a range of motion. The range of motion includes a first limit moving range and a second limit moving range. The first limit moving range is the maximum distance that the movable portion can move toward the light-entering side, and the second limit moving range is the maximum distance that the movable portion can move toward the light-emitting side. When the movable portion is in a predetermined position, the first limit moving range is greater than the second limit moving range.
