Abstract: A camera module includes a mounting frame defining a first through hole, a filter installed in the first through hole, and a circuit board including a first surface and a second surface. The mounting frame is on the first surface. An air escaping channel is recessed from the second surface, an air escaping hole penetrates the first surface and the second surface and communicates with the air escaping channel. The circuit board, the mounting frame, and the filter cooperate with each other to form a first cavity, the first cavity communicates with the air escaping hole. The air escaping channel includes a first channel portion and a second channel portion, an angle is formed between the first channel portion and the second channel portion. The air escaping hole communicates with the first channel portion, the second channel portion extends to an edge of the circuit board to form an opening.
