After electrically grounding by connecting with the grounding pad of the circuit board, the grounding structure connects with the metallic casing and the circuit board. With the grounding structure, the metallic casing can be grounded. Thereby, prevent external electro-magnetic waves from affecting electrical signals communicated between the camera module and the circuit board.
