1. An optical element driving mechanism having an optical axis, comprising;
a fixed portion;
a movable portion, moving relative to the fixed portion; and
a driving assembly, driving the movable portion to move relative to the fixed portion comprising:
a piezoelectric element, having a circular plate shape extending in a second direction and a third direction;
a transmission element, connected to the piezoelectric element;
a clamping element, clamped to the transmission element, and movable relative to the transmission element;
a conversion element, connected to the clamping element two first magnetic elements, disposed on the conversion element and
a second magnetic element, disposed on the movable portion;
wherein the driving assembly moves in a first direction to move the movable portion in the second direction, and the first direction is different from the second direction,
wherein each of the first magnetic elements has a first magnetic pole direction, and the first magnetic pole direction is neither parallel nor perpendicular to the first direction, the second direction, or the third direction.
