The camera module is disposed on the optical image stabilization module, and the optical image stabilization module drives the camera module to perform multi-axis movement to ensure the imaging quality when the electronic device moves. Since the optical image stabilization module needs external power supply, and the internal space of the electronic device is small and the volume of the optical image stabilization module is small, the conventional circuit structure often restricts the movement of the driven module during use, and is also prone to loosening of the electrical connection structure during long-term use, resulting in circuit failures. Summary of the Invention

To this end, the present invention provides an optical image stabilization module with a simple internal circuit connection structure, which can meet the needs of multi-axis rotational movement and improve the stability and reliability of circuit connection. The present invention also provides a camera.

The X-axis flipping plate is disposed inside the substrate and is rotatably connected to the substrate in the X-axis direction. The Y-axis flipping plate is disposed inside the X-axis flipping plate and is rotatably connected to the X-axis flipping plate in the Y-axis direction.
