Optical element driving mechanism

The invention provides an optical element driving mechanism which comprises a fixed part and a movable part. The movable part is movably connected with the fixed part and used for bearing the optical element, and the optical element is provided with an optical axis. The fixing part comprises an opening, a side wall and an opposite side wall. The opening corresponds to the optical element. The side wall has a first thickness and corresponds to the edge of the opening. The opposite side wall has a second thickness and corresponds to the edge of the opening. When observed along the optical axis, the center of the hole deviates from the center of the optical element driving mechanism, and the first thickness is larger than the second thickness. 提供一种光学元件驱动机构，包括：固定部以及活动部。活动部活动地连接固定部，并用以承载光学元件，其中光学元件具有一光轴。固定部包括：开孔、侧壁以及相对侧壁。开孔对应光学元件。侧壁具有第一厚度且对应开孔的边缘。相对侧壁具有第二厚度且对应开孔的边缘。沿着光轴观察时，开孔的中心偏离光学元件驱动机构的中心处，且第一厚度大于第二厚度。
