Abstract: This application provides a camera module, a motor module, an SMA motor, and an electronic device. The camera module includes a lens array, an SMA wire, a drive port of the SMA wire, and an electrical connector electrically connected between the SMA wire and the drive port of the SMA wire. The electrical connector may form a tight coupling relationship with at least one of the following: the electrical connector, the SMA wire, and another electrical connector. Solutions provided in this application help reduce a degree of magnetic interference to a magnetic sensitive electronic component in the camera module.
