A voice coil motor, a camera module, and an electronic device. The voice coil motor includes a motor housing, and a fixed assembly and a moving assembly that are disposed in the motor housing. The fixed assembly and the moving assembly are sequentially disposed in a direction from a light incident side to a backlight side at an interval. The moving assembly is connected to the fixed assembly by using suspension wires. The fixed assembly includes an annular fastening part and a magnetic element. The moving assembly includes an annular circuit board and a flexible mechanism. A coil group is disposed on one side that is of the annular circuit board and that is close to the annular fastening part. One side that is of the moving assembly and that faces the backlight side is configured to connect to an image sensor circuit board.
