OPTICAL ANTI-SHAKE APPARATUS, CAMERA MODULE, AND ELECTRONIC DEVICE

The present disclosure relates to the technical field of optical anti-shake, and specifically to an optical anti-shake apparatus, a camera module, and an electronic device. The optical anti-shake apparatus may comprise a wiring layer, a semiconductor layer, an image sensor, an electromagnetic coil, and a permanent magnet mechanism. The semiconductor layer comprises a fixed part and a movable part which are electrically connected; the fixed part is connected to the movable part by means of a conductive deformation assembly, the fixed part is electrically connected to the wiring layer, and the conductive deformation assembly is used for limiting the movable part in a direction perpendicular to the semiconductor layer. The image sensor is fixed to the movable part and located on the side of the semiconductor layer away from the wiring layer, and the image sensor is electrically connected to the movable part. The electromagnetic coil is fixed to the movable part. The permanent magnet mechanism is used for providi
