Abstract

A camera module includes an optical lens, a photosensitive sensor and an electrical support. The electrical support includes a circuit arrangement embedded in a support body to form an integral structure, a connecting member provided on the support body to electrically connect with the circuit arrangement, and a camera component coupled at the support body and electrically connected to the connecting member. Therefore, the electrical support not only forms a circuit board to electrically connect with the camera component but only serves as a base to support the camera component.
