Abstract: A camera module protection structure includes a circuit board, a case and a camera device. The case is disposed on the circuit board. At least one side of the case is formed with a securing section. The case is formed with a receiving space in a position corresponding to the securing section. The camera device is correspondingly disposed in the receiving space. According to the structural design of the camera module protection structure, the securing section of the case is able to enhance the structural strength of the entire camera module and greatly lower the damage ratio of the camera module and prevent the circuit board from being easily broken off or damaged in assembling process of the camera module.
