Abstract: A driving module is provided. The driving module includes a fixed portion, a movable portion movably connected to the fixed portion and used to hold an optical element having an optical axis, a driving assembly for driving the movable portion to move relative to the fixed portion, and a circuit assembly electrically connected to the driving assembly. The circuit assembly includes a first segment, a second segment, and a third segment. The first segment is resilient, plate-shaped, and movable relative to the fixed portion and the movable portion. The second segment is plate-shaped and affixed on the movable portion, wherein a thickness direction of the first segment is different from a thickness direction of the second segment. The third segment is plate-shaped and affixed on the fixed portion, wherein the second segment is movably connected to the third segment through the first segment.
