Abstract
An optical member driving mechanism is provided. The optical member driving mechanism includes a fixed portion, a movable portion, an electromagnetic driving assembly and an elastic member. The fixed portion has a base and a frame that is disposed on the base. The movable portion is movable relative to the fixed portion, and includes a carrier for carrying an optical member with an incident optical axis. The carrier includes a body and a sidewall that extends along the edge of the body. The electromagnetic driving assembly drives the movable portion to move relative to the fixed portion. The movable portion is movably connected to the fixed portion via the elastic member, wherein as viewed along the incident optical axis, the sidewall and the elastic member at least partially overlap.
