Abstract

An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed part, a movable part, a driving assembly, and a sensing assembly. The fixed part has a main axis. The fixed part includes a case and a bottom. The case and the bottom are arranged along the main axis. The movable part moves relative to the fixed part. The movable part may hold an optical element with an optical axis. The driving assembly drives the movable part to move relative to the fixed part. The sensing assembly senses a movement condition of the movable part relative to the fixed part. The sensing assembly includes a sensor. The sensor is disposed on the bottom.
