A camera module includes a positioning plate, a positioning frame, a spring member, a lens holder, and a piezoelectric actuator. The positioning frame is fixed to the positioning plate and defines a positioning through hole. The spring member is disposed on the positioning plate and in a compressed state. The lens holder is received in the positioning through hole and movably engaged with the positioning frame. The piezoelectric actuator is sandwiched between the compressed spring member and the lens holder. The piezoelectric actuator is operable to drive the lens holder to rotate about a central axis of the positioning frame, thereby move along the central axis relative to the positioning frame.
