  • Patent number: 11022726
    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.
