Abstract: An optical driving mechanism is provided, including a movable portion, a bottom plate and a biasing assembly. The movable portion is configured to sustain an optical element having an optical axis. The bottom plate has a moving member. The biasing assembly has at least one biasing element for driving the movable portion to move relative to the bottom plate. The bottom plate defines a first electrical connection portion and a second electrical connection portion, and the biasing element is connected to the first and second electrical connection portions. The first electrical connection portion has a fixed body, an insulating layer and a conductive layer, which are sequentially overlapped along the optical axis. The conductive layer is directly and electrically connected to the biasing element. When viewed along the optical axis, the insulating layer protrudes from the fixed body and the conductive layer.

Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a carrier, a base, and a first driving assembly. The carrier holds an optical element with an optical axis. The carrier is movably connected to the base. The first driving assembly drives the carrier to move relative to the base. The first driving assembly includes a driving coil disposed on the carrier, and the direction of the winding axis of the driving coil is different from the direction of the optical axis. The carrier has an abutting surface, which faces and is in direct contact with the driving coil. The maximum size of the abutting surface is greater than the maximum size of the driving coil in the direction of the optical axis.
