Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly, and a position-sensing assembly. The movable assembly corresponds to an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The position-sensing assembly is configured to sense the movement of the movable assembly relative to the fixed assembly, and the position-sensing assembly includes a sensed unit and a sensing element. The sensing element corresponds to the sensed unit. The sensed unit has a plurality of reference magnetic elements arranged in a first direction, the sensed unit and the sensing element are arranged in an arrangement direction, and the first direction is not parallel to the arrangement direction.
