Claim 16:
17. An optical element driving mechanism, comprising: a fixed portion having a main axis; a movable portion movably disposed on the fixed portion and connected to an optical element; a driving assembly driving the movable portion to move relative to the fixed portion; wherein the movable portion comprises: a first movable portion movably connected to the fixed portion; and a second movable portion movably connected to the first movable portion and connected to the optical element; wherein the driving assembly comprises a transmission element, a first resilient element, and a driving element, and the driving element drives the transmission element through the first resilient element to move in a first direction; wherein the first movable portion moves in the first direction, the second movable portion moves in a second direction that is different than the first direction, and the transmission element is movably connected to the first movable portion; and an intermediate element and a bonding element, wherein the intermediate element is positioned between the first movable portion and the second movable portion, the first movable portion comprises a first sliding surface and the second movable portion comprises a second sliding surface, wherein the first sliding surface faces the second sliding surface, and the first sliding surface and the second sliding surface are neither perpendicular nor parallel to the first direction or the second direction, wherein the intermediate element is disposed between the first sliding surface and the second sliding surface; a first recess is positioned on the first sliding surface extending in the first direction when viewed in the second direction, and the intermediate element is disposed in the first recess, a second recess is positioned on the second sliding surface extending in the first direction when viewed in the second direction, and the intermediate element is disposed in the second recess, the driving assembly is connected to the fixed portion via the bonding element, the fixed portion further comprises a base, and the driving assembly is connected to the base via the bonding element, the base comprises a first connecting surface that is parallel to the second direction, the driving assembly comprises a second connecting surface that is opposite the first connecting element, and the bonding element is disposed between the first connecting surface and the second connecting surface, the first connecting surface at least partially overlaps the transmission element when viewed in the first direction.
