1. An optical element driving mechanism, comprising:
a holder, configured to be connected to an optical element;
a casing, having a top wall and a side wall, wherein the top wall having a plate-shaped structure is not parallel to the side wall having a plate-shaped structure;
a driving assembly, configured to drive the holder to move relative to the casing; and
wherein the top wall has an anti-twist structure extending toward the holder, a twist-proof recess corresponding to the anti-twist structure is formed on the holder, and the optical element driving mechanism further includes a first shock absorbing member directly contacting the anti-twist structure and the twist-proof recess.
