1. An optical element driving module, comprising:
a fixed part;
a movable part movable relative to the fixed part, wherein the movable part holds an optical element with an optical axis;
an elastic element connected to the fixed part and the movable part;
a driving assembly driving the movable part to move relative to the fixed part, wherein the driving assembly comprises a coil and a magnetic element corresponding to the coil; and
a damping element inhibiting shake generated by the movable part,
wherein a top surface of the damping element is in direct contact with the elastic element,
wherein the fixed part comprises a fixed part recess, the fixed part recess comprises a first surface facing the damping element and not parallel with the optical axis, and a bottom surface of the damping element is in direct contact with the first surface and covers entirety of the first surface,
wherein the fixed part recess further comprises a second surface facing the damping element and not perpendicular to the optical axis and a third surface facing the damping element and not perpendicular to the optical axis,
wherein the second surface and the third surface are connected to the first surface, and a receiving space having a U-shaped profile is formed by the first surface, the second surface, and the third surface.
