1. An optical element driving mechanism, comprising:
a movable part, for connecting an optical element;
a fixed part, wherein the movable part is movable relative to the fixed part;
a driving assembly, comprising a driving magnetic and a drive coil, for driving the movable part to move relative to the fixed part; and
a first supporting assembly, wherein the movable part is movable relative to the fixed part through the support of the first supporting assembly,
wherein the first supporting assembly is at least partially located between the movable part and the fixed part,
wherein the first supporting assembly comprises:
a first supporting element, having an elongated shape, and extending along a first axis;
a first accommodating structure, having a recessed structure, and accommodating the first supporting element;
a fourth intermediate element, corresponding to the first supporting element;
a fourth intermediate element groove, wherein the fourth intermediate element is located in the fourth intermediate element groove;
wherein the fourth intermediate element at least partially overlaps the first supporting element when viewed along the first axis,
wherein the fourth intermediate element groove is formed in the first accommodating structure,
wherein the fourth intermediate element is in direct contact with the first supporting element,
wherein the first supporting element is movable relative to the fourth intermediate element.
